REMARK
Weight of component whose weight is heavier than 25 kg is shown with symbol
in "DISASSEMBLY AND
ASSEMBLY".
• Before starting work, check the wire ropes, brake, clutch, controller, rails, over winding prevention device,
ground fault circuit interrupter for electric shock prevention, crane collision prevention device, and energiz-
ing caution lamp, and check the following safety items.
• Observe the signals for sling work.
• Operate the hoist at a safe place.
• Be sure to check the directions of the direction indication plate (north, south, east and west) and the
operating button.
• Do not sling a load at an angle. Do not move the crane while the slung load is swinging.
• Do not raise or lower a load while the crane is moving longitudinally or laterally.
• Do not drag a sling.
• When lifting up a load, stop it just after it becomes off the ground, check the safety, and then lift it up.
• Consider the travel route in advance and lift up a load to a safe height.
• Place the control switch in a position where it is not an obstacle to work and passage.
• After operating the hoist, do not swing the control switch.
• Remember the position of the main switch so that you can turn off the power immediately in an emer-
gency.
• If the hoist stops because of a power failure, turn off the main switch. When turning on a switch after it
is turned off by the ground fault circuit interrupter, check that the devices related to that switch are not
in operating condition.
• If you find an obstacle around the hoist, stop the operation.
• After finishing the work, stop the hoist at the specified position and raise the hook to at least 2 m above
the floor. Do not leave the sling installed to the hook.
Selecting wire ropes
Select adequate ropes depending on the weight of the parts to be hoisted referring to the table below.
REMARK
The allowable load is calculated with one sixth (safety factor 6) of the breaking load of the rope.
Wire rope (JIS G3525 6x37-A type) (Standard Z twist wire ropes without galvanizing)
