CRANE- Concept
The cranes represent the most important links in the network of production and are
essential for the transport of material in all the Company premises.
Represent a large capital investment, because its price is ten to fifty times that of a
standard automobile.
Thus, it is a great responsibility to operators for their safe and skillful operation of
their charges.
A good trader knows everything that relates to your bridge: capacity, speed, signal
men's floor and safety rules.

TRANSLATION OF CRANE
• CRANE MOVES FREELY AS THE TROLLEY AND, IN THE SAME WAY THAT THIS HAS NO
LIMIT KEY ENDS IN THE STRUCTURE OF TRANSLATION TO TURN OFF THE POWER TO THE
BRIDGE AND STOP.
• THE FOUR CORNERS OF CRANE ARE EQUIPPED WITH BUMPER SPRING, WHICH, IF NOT
RELY TO OPERATE THE CRANE.
• THESE BUMPERS CONSTITUTE A MEANS OF SECURITY TO PROTECT THE ENDS OF
BUILDINGS AND OTHER CRANE THAT IS THE SAME BEAMS OF TRANSLATION.
• BEFORE REACHING THE END OF BEAMS OF TRANSLATION MUST STOP THE CRANE
COMPLETELY AND THEN, WITH SHORT AND SLOW MOVEMENTS, COMPLETE THE PATH
UNTIL THE BUMPER OF CRANE AND THE STRUCTURE OF TRANSLATION IS TOUCH
LIGHTLY.
• IN SPITE OF CRANES BE PROTECTED WITH DIRECTIONAL RELAY AGAINST REVERSALS
SUDDEN, THEY, HOWEVER, DO NOT ACCEPT REVERSAL INSTANTLY.

LUBRIFICATION
PROPER LUBRICATION IS ONE OF THE MOST IMPORTANT PARTS OF
MAINTENANCE OF CRANES AND OPERATING YOUR SAFETY.
THEREFORE A GOOD LUBRICATION IS CRITICAL TO PREVENT
EXCESSIVE WEAR PARTS AND / OR FREQUENT STOPS FOR BREACH.
THE SIX MAIN FUNCTIONS OF GREASE IS:
 REDUCE WEAR;
 REDUCE FRICTION;
 MINIMIZE THE ACCUMULATION OF DUST;
 PREVENT RUST;
 ABSORB HEAT;
 IMPROVING POWER TRANSMISSION.

SAFETY STANDARDS

LUBRIFICATION
ENGINES AND REDUCING THE BOXES ARE COMPLEX AND NEED VARIETY OF SPECIAL
LUBRICANTS AND QUANTITY AND TIME CORRECT REPLACEMENT.
IN SOME CASES, GREASE OR OIL IN TOO ARE SO BAD OR EVEN WORSE THAN THE LACK OF
LUBE.
THESE SYSTEMS, EACH IN CONNECTION WITH A CYCLE IS LUBRICATED PRE-DETERMINED
AMOUNT OF GREASE.

COMMAND OR KEY LEVER
TO REALIZE THAT MECHANICAL OPERATIONS, SUCH AS START, ACCELERATION, DECELERATION,
STOP AND REVERSE IN OTHER EQUIPMENT OF A CRANE, WE SHOULD BE ABLE TO CONTROL THE
FLOW OF ELECTRICITY IN STARTER MOTOR CIRCUIT OF SUCH EQUIPMENT. THIS IS MADE THROUGH
THE USE OF LEVER, WHICH, IS DESIGNED TO PERFORM AS DESIRED CHANGES IN THE CIRCUIT
ELECTRIC MOTOR (USUALLY CALLED CIRCUIT POWER). OPERATION OF CONTROL EQUIPMENT (TIMER)
CAN BE DESCRIBED AS FOLLOWS SIMPLIFIED:

Power
Line

Control
Panel

Key Switch

MOVE KEY CONTROL (LEVER) ENTAILS OPERATION ELECTRO DEVICES (RELAYS AND
CONTACTORS) CONTROL PANEL .. THESE DEVICES INTERRUPT THE FLOW, REVERSE
DIRECTION OF FLOW OR CHANGE THE AMOUNT OF ELECTRICITY THAT GOES TO THE ENGINE,
CHANGE THROUGH THE QUANTITY OF RESISTANCE IN THE CIRCUIT POWER. THEREFORE,
THE ENGINE STOPS, REVERSES THE DIRECTION OF ROTATION, REDUCE OR INCREASE YOUR
SPEED IN RESPONSE TO THESE CHANGES POWER.
BEYOND THE FUNCTIONS OF STARTING, REVERSE THE DIRECTION OF ROTATION, THE
SPEED CONTROL AND STOP THE ENGINE, THE CONTROL EQUIPMENT STILL HAS THE
PURPOSE OF PROTECTING THE ENGINE. BUT, LET'S SEE:
THE DEPARTURE DUE TO COAST, THE ENGINE THAT REQUESTS A HIGH CURRENT, IF NOT
LIMITED THROUGH RESISTANCE INCLUDED IN THE CIRCUIT, DAMAGE THE WINDING THROUGH
THE ENGINE (CASE WOULD, FOR EXAMPLE, IF THE LEAD TO SUDDENLY LEVER FOR MAXIMUM

SPEED POINT WHERE ALL THE STRENGTH CIRCUIT IS ELIMINATED). WHAT THIS DOES NOT
OCCUR, THE CONTROL EQUIPMENT CONSISTS OF CONTROL DEVICES timed THAT THE
WITHDRAWAL OF RESISTANCE BY STEP, CONTROLLING ALSO, THEREFORE, THE POWER OF
THE ENGINE WHEN THE LEVER IS SUDDENLY TAKEN BEYOND THE SECOND POINT.

ANOTHER HIGH CURRENT SITUATION THAT ENTAILS THE ENGINE IS THE REVERSAL OF
QUICK APPLY, BECAUSE HOW CAN CONCLUDE: IF REQUESTED BY THE CURRENT ENGINE IS
STOPPED WHEN IT IS HIGH. WHEN APPLYING REVERSE, A CRANE IS RUNNING TOWARDS THE
CONTRARY TO WHAT IS ON THE ENGINE, MECHANICAL INERTIA DRIVEN BY ASKING, SO
CURRENT HIGHEST. IN THIS CASE, NOT ONLY CAN DAMAGE THE ENGINE ITSELF, AS THE
MECHANICAL COMPONENTS, SUCH AS GEARS, SHAFTS, CONNECTORS ETC. TIMER EVITA
OCCUR THROUGH SUCH DEVICES THAT KEEP ALL THE STRENGTH CIRCUIT, LIMITED
CURRENT SPEED TO GET TO ZERO AND THE ENGINE STARTS TO TURN TOWARDS WHICH IS
ON GIVING HOME TO CONTROLLED ACCELERATION.
SYSTEM CURRENT CONTROL DURING THE PERIOD OF ACCELERATION AND REVERSAL OF
CRANE, IS NOT SUFFICIENT TO GIVE PROTECTION TO TOTAL ENGINE, AS IT IS ONLY ACTIVE
SYSTEM DURING THAT PERIOD. IN CASE OF MISFIT RELAY TIMED, GRABBING THE
MECHANICAL PARTS OF CRANE OR SHORT CIRCUIT IN RESISTANCE, THE ENGINE WOULD BE
SEVERELY BURNED IN EXCESSIVE CURRENT IF THE CONTROL SYSTEM WERE NOT GIFTED
OVERCURRENT RELAYS ABSCHALTEN THAT WHEN THE ENGINE CURRENT EXCEEDS THE
LIMIT PRE-DETERMINED.

 ELECTROMAGNETIC BRAKE
ALL ELECTRIC BRAKES ARE DESIGNED IN ORDER TO BE RELEASED WHEN
CIRCULAR ELECTRIC CURRENT ON HIS WINDING. IN OTHER WORDS, THEY ARE
ACTUATED BY SPRING AND ELECTRICALLY RELEASED. SO, WHEN APPLIED IN AN
ELECTRIC CURRENT BRAKE COIL, MAGNETIC FIELD IS ESTABLISHED A STRONG
ENOUGH TO WIN THE STRENGTH OF SPRING AND ATTRACT A PISTON OR STEEL

MECHANICAL LOAD BRAKE
BRAKE IS A LOCK THAT ONLY WORKS ON DESCENT OF CHARGE. WHEN THIS UP,
BRAKE IS LOOSE SO THERE'S NO "entrainment" NO MOTOR.

REVERSAL
IS THE MOVEMENT CONTROL IN OPPOSITE DIRECTION TO THAT ON WHICH THE
CHARGE OR THE CRANE IS JOGGING. THIS IS A CHAIN REVERSE THAT STOPS THE

MOVEMENT OF FRONT LOAD OR MOTOR. WHEN THE LOAD IS STILL, THE LEVER
MUST STAY IN CONTROL CENTER, IN THE "OFF", OTHERWISE, WILL VERIFY AN
ENGINE ACCELERATION IN OPPOSITE DIRECTION.

OBLIQUITY
APPLIES, GENERALLY, THE MOVEMENT OF THE CRANE.
IS A CONDITION THAT TAKE PLACE WHEN THE BEAMS ARE NOT PERPENDICULARS
CRANE RAILS TO INDICATE THE STRUCTURE OF TRANSLATION, SO THAT ONE OF
EDGES OF CRANE IS MORE ADVANCED THAN THE OTHER, WHAT CONSTITUTES AN
ERROR THAT SHOULD BE CORRECTED WITHOUT LOSS TIME.

TORQUE
WORDS THAT TERM IS THE CAPACITY OF A MOTOR TO PROVIDE OR FORCE TO
TURN AROUND AXLE AND PRODUCE YOUR WORK. TORQUE OF A MOTOR CAN BE
CHANGED BY MEANS OF A CONTROL IN ACCORDANCE WITH THE REQUIREMENTS
OF CHARGE.

STOPS
MOST OF CRANES IS NOT PROVIDED FOR LIMIT SWITCH IN THE END, TO TURN OFF
THE POWER TO STOP THE ENGINE AND THE TROLLEY. TROLLEY OF THE RAILS ARE
EQUIPPED WITH STOPS IN THE END, AND SHOULD BE TAKEN VERY CAREFULLY TO
AVOID THAT THEY ARE AFFECTED BY TROLLEY TO HIGH SPEED, WHICH MAY RESULT IN
HAZARDOUS DERAILMENT.
TO MAKE THE TROLLEY STOPS IN TOUCH IN ORDER TO RAISE OR LOWER A LOAD OF
CRANE IN THE END, IT IS RECOMMENDED THAT THE TROLLEY BE TAKEN TO A SHORT
DISTANCE OF STOPS AND THEN STOP. THEN THROUGH SHORT MOVES, MOVES UP THE
TROLLEY TO TOUCH THE STOPS, SETTING UP, THEN THE LEVER CONTROL CENTER, IN

INTRODUCTION
 MOVES ARE COMMANDED BY THE TOW COMMAND KEY (LEVER) CORRESPONDENT AND
CONTROLLED ELECTRICAL CIRCUITS SPECIALLY DESIGNED FOR THIS PURPOSE. THE
MOVEMENT IN THE DIRECTION OF THE TOW UP, OBVIOUSLY, ALWAYS ASKS POWER MOTOR,
WITH OR WITHOUT CHARGE SLING. IN DIRECTION DOWN, THIS POWER IS REQUIRED WHEN
THE TOW DOWN LOAD AND LOADS WITH LIGHT SLINGS, BUT WHEN THE HOIST DOWN WITH A
HEAVY LOAD, THIS TEND TO DRAG THE ENGINE, REQUIRING THIS EVENT OF A BRAKE FOR
SPEED CONTROL.

LIFTING
ADVANCING THE KEY COMMAND (LEVER) FOR THE FIRST POINT TO CLIMB, THE BRAKE IS
RELEASED AND UPWARD MOVEMENT OF WINCH IS STARTED SLOWLY DUE TO LOW TORQUE
MOTOR CAUSED BY THE LARGE AMOUNT OF RESISTANCE IN EXISTING CIRCUIT. INCREASED
VALUES OF TORQUE AND SPEED OF SURVEY IS DONE IN POINTS AFTER THE KEY COMMAND
(LEVER), UP GRADUALLY DECREASING THE AMOUNT OF RESISTANCE OF THE MOTOR
CIRCUIT. LAST POINT, THE ENGINE IS DIRECTLY ON THE LINE, THAT IS, WITHOUT ANY
RESISTANCE IN THE CIRCUIT AND TOW ACHIEVE YOUR MAXIMUM RAMP. TOW IN ANY
POSITION, KEY CONTROL (LEVER) CAN BE CENTERED TO APPLY THE BRAKE AND STOP THE
UPWARD MOVEMENT.

DEFINITIONS
WHEN READY TO LIFT A LOAD, USA UP THE FIRST POINT OF CONTROL TO TAKE THE
CLEARANCE OF WARE ROPE. THIS PREVENTS STRID AND DEFORMATION OF CABLE. WHEN
IS STRETCHED CABLE, START UP A LEVER CONTROL SLOWLY BACK UNTIL THE LOAD
START MOVING. THEN MOVE THE SAME STEP BY STEP, TO ACHIEVE MAXIMUM SPEED. TO
SUSPEND A LOAD, THE ENGINE HAS TOW RISING IA ACTION AGAINST GRAVITY, WILL HAVE
TO EXPEND MORE EFFORT TO MOVE A HEAVY LOAD THAN A LIGHT, AND, YOU WILL START
WITH A SLOWER THAN HEAVY LOAD WITH A LIGHT LOAD. BRAKE WINCH IS LOOSE WHEN
THE ENGINE IS DRIVEN AND OPERATES. TO SUSTAIN LOAD IN ANY POSITION, WHEN THE

•

•

Devices, for the most part optical transmission, which aims to define a
security distance between two or more cranes which share the same
translation beam or are in another collision situation, for example crane
beam with translation of and under one another.
This safety distance aims to avoid the collision between the cranes or eg
preventing two or more cranes will access the same beam translation at

In a study of deactivation. It makes no sense to set boundaries and
limit anti collision using this button. It is a source of accidents,
especially collision.

GENERAL SAFETY
 LOCK HOOK

GENERAL SAFETY
 LIMIT SWITCH
IS A SAFETY DEVICE THAT LIMITS THE SPACE CRANE LIFTING AND IS NOT TO
BE USED CONTINUOUSLY.
 TO AVOID THE HOOK OF CRANE EXCEED THE NORMAL COURSE TO RAISE, THE CRANES

ARE EQUIPPED WITH A KEY LIMIT. ONE OF THE KEY TYPES OF LIMIT MORE COMMON IS THAT
WHICH IS OPERATED BY OWN HOOK. OTHERWISE, IS WHAT IS ON THE DRUM AND IS ALWAYS
READY TO DROP AFTER A CERTAIN NUMBER OF TURNS OR THE DRUM SPINS.
 KEYS LIMITS ARE INSTALLED IN ORDER TO TURN OFF THE POWER ENGINE WHICH

AUTOMATICALLY, ACT DOES DYNAMIC BRAKE. WHEN IS OPERATED LIMIT SWITCH, REVERSES
UP CONTROL TO LOWER THE HOOK; THIS OPERATION MUST BE DONE "GIVING HITS" IN
CONTROL TO GET THAT LIMIT SWITCH REPLACEMENT. SOME KEYS NO LIMIT ONLY
ABSCHALTEN ENGINE LINE ALSO HOW DO YOU STOP QUICKLY THROUGH AN ELECTRIC
BRAKE. AVOID THIS ONE "entrainment" EXCESSIVE AND ALLOW THE LIMIT SWITCH IS SET WITH
A MINIMUM CLEARANCE BETWEEN THE HOOK DRUM AND, THUS LEAVING A COURSE THAT
ELIMINATES MOST FREQUENT OPERATION OF THE SAME.

GENERAL SAFETY
 CHAVE LIMITE
 ALTHOUGH ONE STOP UP, YOU SHOULD KEEP IN MIND THAT

HER DOWN THERE. IF THE ENGINE THEN CONTINUE ON THE
HOOK TO TOUCH THE FLOOR, THE CABLE WILL LEAVE YOUR
POSITION AND DRUM ROLL ON BEGIN IF COUNTER. WHEN
OCCURS, IMMEDIATELY STOP THE OPERATION OF CRANE, AND
COMMUNICATE TO CALL MAINTENANCE SUPERVISOR WITHOUT
LOSS OF TIME, BECAUSE THE WINDING CABLE IN OPPOSITE
DIRECTION CAN CAUSE SERIOUS DAMAGE TO THE CRANE.
 ALSO LIMIT THE KEY GOES DEAD. IF YOU CONTINUE IF
CABLE ROLL IN OPPOSITE DIRECTION, THE HOOK CAN strike
the DRUM, WARE FROM THE ROPE AND DROP THE LOAD,
DAMAGING THE BRIDGE AND CAUSING SERIOUS ACCIDENT
WITH MEN'S FLOOR.

determining when the coil is centered hole. That is, the close command will only be
allowed if the sensor detects the alignment of the arms of the central hole of the coil,
in order not to damage the edges of the coil.

•

Sensors edges
One located in each gripper, has the purpose of determining the lateral edges of the
coil, that is, the close command is interrupted when both edge sensors detect the
presence of the edges of the coil, in order not to leave knead them or damaging them
.

RECOMENDATIONS
NOT WORK WITH A CRANE WITHOUT KNOWING HOW ARE
THE CONDITIONS OF ITS COMPONENTS.
TO WORK WITH A CRANE, YOU SHOULD MAKE AN
INSPECTION:
- KEY EMERGENCY OFF:
1- CHECK IN PANELS OR IF THERE PADLOCKS SAFETY LABELS IN THE KEYS OR PREY IN
BREAKERS.
2- CHECK IN GENERAL KEY, IF THE SAME IS OFF OR BLOCKED.
3- CHECK THAT THE COMPONENTS OF TRANSLATION OF RP IS IN GOOD CONDITIONS;
4- CHECK THAT THE INGREDIENTS ARE IN GOOD CONDITIONS TROLLEY;
5- CHECK THAT THE SYSTEM COMPONENTS LIFTING ARE IN GOOD CONDITION;
6- CHECK THE BAR MAIN POWER SUPPLY;
7- CHECK IF SOMETHING CAN STOP THE WHEELS OF TROLLEY OR CRANE MOVE
AROUND ON RAILS;
8- CHECK THAT THE WARE ROPE ARE IN GOOD CONDITIONS;
9- CHECK THE BOUNDARY CONDITIONS OF TOW;

RECOMENDATIONS
NOT WORK WITH A CRANE WITHOUT KNOWING HOW ARE
THE CONDITIONS OF ITS COMPONENTS.
TO WORK WITH A CRANE, YOU SHOULD MAKE AN
INSPECTION:
- KEY EMERGENCY OFF:
10- VERIFY THE EXISTENCE OF PARA-SHOCK THE TROLLEY AND CRANE;
11- VERIFY THE EXISTENCE OF THE STOPS AND TROLLEY CRANE;
12- CHECK THE CONDITIONS OF LEVER AND BRAKE PEDAL.

BEING ALL IN GOOD CONDITION:
ON A CRANE AND MAKE TESTS WITH
ALL CARE AND TRAVELING CRANE:
TROLLEY, TOW, LIMIT SWITCH AND SIREN.

THEN YOU MUST INITIATE THE WORK.

IMPORTANT
 NEVER

LEAVE YOUR CRANE EXCEPT WHEN ABSOLUTELY
NECESSARY. WAIT IN THE CABIN OF YOUR ARRIVAL SUBSTITUTE
AUTHORIZED BY SUPERVISOR;

 TRANSPORT NOT OXYGEN CYLINDER ACETYLENE OR FULL OR
EMPTY AND DEVICE ELECTROMAGNETIC LIFTING BY ORDER OF
WHOEVER IS;

 SUDDENLY NOT APPLY THE BRAKE FOOT,. OS "corns" WHEELS
SKATING RESULTING FROM THE CRANE;

 REMEMBER:
- AFTER ALL, THE SAFE OPERATION OF THE CRANE IS YOUR
RESPONSIBILITY;
- THE LIFE OF A LOT DEPENDS ON YOUR CONSTANT CARE AND ITS
COMMON SENSE.

IMPORTANT
LIGHTING:
CRANE HAS SHED THAT SHOULD HAVE REFLECTORS HUNG CEILING IN ANY
EXTENSION;
IN SECTORS WHERE ARE PERFORMED MAINTENANCE SERVICES, YOU SHOULD
INCREASE THE NUMBER OF REFLECTORS;
WAREHOUSE IN THE CLOSED SIDE REFLECTORS MUST OWN THE OPPOSITE SIDE OF
CABIN PR, NO CAUSE FOR REFLECTIONS AND SHADOWS THAT UNDERMINE VISIBILITY OF
OPERATORS;
WELLS AND GALLERIES WITH REFLECTORS MUST HAVE DIRECTED TO FOCUS IN OR
FOR THE OPENING OF WELL;
WELDING SERVICES, OR TORCHES REFLECTIONS OF LIGHT COME OF WATER WELLS,
MIRRORS ETC, SHOULD BE ELIMINATED OR, IF YOU CAN NOT, MUST BE PROTECTED WITH
SCREENS;
THE WINDOWS OF CABINS CRANE SHOULD BE DESIGNED WITH REFLEX TO BREAK OUT
OF CABIN;
GLASSES OF BOOTHS ARE NOT TO BE DESIGNED, ONE IN FRONT OF THE OTHER, THE
VERTICAL POSITION TO PREVENT FALSE IMAGES.

IMPORTANT
ALL CRANE HAVE TO OWN THE SIREN FUNCTIONING. THE OPERATOR SHALL USE IT
EVERY TIME WORKING WITH CRANE.
THERE ARE SEVERAL TYPES OF SIREN, CRANE IS USED FOR TYPE PATTERN, MUST NOT
CHANGE THE TYPE OF SIREN CRANE BECAUSE THAT'S THAT SOUND STAFF AREA HAS
HABIT TO HEAR;
ACTIVITIES THAT OFFERS GREAT RISK, THE SIREN WILL BE DRIVEN INSISTENTLY;
PEOPLE WORKING IN AREAS WHERE HAVE CRANE, BE TARGETED AS THE RISKS OF
SUSPENDED LOAD;
PEOPLE WHO USE CRANE, BE TRAINED TO SIGNAL OPERATOR USING SLINGS, HAVING
KNOWLEDGE OF SAFETY RULES.
IMPORTANT:
BEFORE ENTERING AN AREA THAT HAS CRANE, PEOPLE SHOULD STOP AT THE
ENTRANCE OF THE SHED AND LOOK UP, CHECK THE POSITIONING OF AVOIDING CRANE
SO PASS UNDER LOAD SUSPENDED.

"SAFETY IS A MATTER OF
ATTITUDE!"

IMPORTANT
AIR CONDITIONING
THE CRANE THAT TEEM AIR CONDITIONING, THE OPERATOR MUST GIVE ATTENTION
TO:
• KEEPING CLEAN FILTERS INCREASE THE LIFE OF AIR CONDITIONING;
• CABIN SHALL HAVE CHINKS IN WINDOWS FOR THE CLIMATE IS NOT IMPAIRED TO AIR
OUT. DOORS MUST BE CLOSED AND SEALED WITH RUBBER;
• THE THERMOSTAT ADJUSTMENT SHALL BE IN ACCORDANCE WITH THE CLIMATE OF
SEASONS. SUMMER IS VERY SOUGHT. THE OPERATOR MUST TURN OFF THE AIR AT
LEAST ONE TIME, TWO TIMES A DAY, AND WHEN YOU DO NOT HAVE TO BE OFF THE
CABIN AIR;
• IRREGULARITIES SHOULD BE AS NOTED IN REPORT OF INSPECTION AND SERVICE IN
CHARGE SCHEDULED MAINTENANCE AND ROUNDS SCHEDULED.
•IMPORTANT:
MAINTENANCE SHOULD BE AVAILABLE IN WORKSHOP SOBRESSLENTES GOOD
QUALITY, PERFORMANCE MONITORING, GIVE IMMEDIATE ASSISTANCE IN EMERGENCY
ISSUES ELIMINATE NOT LEAVING ACCUMULATE, SEEK EMERGENCY ZERO AND GIVE THE
CRANE OPERATIONAL AVAILABILITY

IMPORTANT
LIGHT SIGNAL
ALL CRANE SHOULD SIGNAL LIGHTS ON THE STRUCTURE OF THE CABIN AND
OUTSIDE:
- RED ON - INDICATES THAT THE CRANE IS ON.
- GREEN ON - INDICATES THAT THE CRANE IS OFF.
PERSONNEL WORKING AT AREA SHOULD HAVE KNOWN THAT, WITH A RED SIGNAL
LIGHT ON, YOU MAY NOT GO UNDER THE CRANE BECAUSE SHE COULD MOVE ANYTIME.
THE CRANE LIFTING DEVICE USING ELECTROMAGNETIC ALSO USE RED SIGNAL LIGHT.
BEING THE SAME ON, INDICATES THAT THE PANEL IS ON AND THE ELECTROMAGNETIC
LIFTING DEVICE IS BEING USED.
IMPORTANT: THE OPERATOR OF FLOOR SHALL NOT CONNECT AND DISCONNECT THE
PLUG'S LIFTING DEVICE ELECTROMAGNETIC SIGNAL WHEN THE LIGHT IS LIT EVEN BEING
OFF, WAIT FOR APPROVAL OF THE CRANE OPERATOR SIGN IN CONVENTIONAL (OPENING
ARMS).

IMPORTANT
REVOLVING SIGN LIGHT AND SOUND:
THE EQUIPMENT THAT EVERYWHERE THE FLOOR WHERE HAS CRANE, SHOULD SIGNAL
LIGHT AND SOUND TO AWAKEN THE ATTENTION OF OPERATOR AND PERSONNEL WORKING
IN AREA.
STATIONARY EQUIPMENT LOCATED IN THE AREA AND THAT MAY BE FOR LOADS RAMMED
HOISTED BY CRANE ALSO SHOULD SIGNAL LIGHT / SOUND.

FIRE EXTINGUISHERS :
IT IS RECOMMENDED TYPE CO2, DUE TO ELECTRICAL COMPONENTS IN EXISTING CRANE.
MUST HAVE AN ENTRY IN OR INTO THE CABIN AND ONE ON THE CATWALK TO THE SIDE
PANELS OF THE GENERAL KEY.
OBS.: CRANE BEING A LARGE AND WITH MANY COMPONENTS SHOULD HAVE ANOTHER
EXTINGUISHER. MUST HAVE YET ANOTHER EXTINGUISHER NO TRICK, SIDE CABIN TO MEET
THE ENGINES AND TOW TROLLEY.
IMPORTANT:
ACCORDING TO THE SIZE AND NUMBER OF EXISTING ELECTRICAL COMPONENTS, THE
AMOUNT OF EXTINGUISHERS MUST INCREASE IN PROPORTION TO REQUIREMENTS
OPERATING PROCEDURE.
