16 IMT Electric-Hydraulic Crane Operation & Safety Manual # 99903618
2 If operational aids are inoperative or malfunctioning, do not use the crane to lift any loads.
Warning Sign
If there is a warning sign on the crane controls, do not operate the crane until the warning sign
has been removed by an appointed person.
Attaching the Load
1 Do not wrap the hoist rope around the load.
2 Attach the load to the hook using slings or other devices of sufficient capacity.
Holding the Load
1 Test crane controls at the start of a new shift. If any controls fail to operate properly, they
must be adjusted or repaired before operations are begun.
2 Do not leave the controls while the load is suspended.
3 Do not allow anyone to stand or pass under a suspended load.
Moving the Load
1 Make sure:
a) The crane is level and blocked, where necessary.
b) The load is well secured and balanced in the sling or lifting device before it is lifted more
than a few inches.
c) The lift and swing path is clear of obstructions.
2 Before starting the lift, make sure:
a) The hoist rope is not kinked.
b) Multiple–part lines are not twisted around each other.
c) The hook is secured to the load in such a manner as to minimize swinging.
d) In case of a slack rope condition, the rope must be seated on the drum and in the
sheaves as the slack is removed.
e) The effect of ambient wind on the load and on crane stability is taken into consideration.
3 During the lifting operations, make sure:
a) There is no sudden acceleration or deceleration of the moving load.
b) The load, boom or other parts of the machine do not contact any obstruction.
4 Limit boom side loading to freely suspended loads. The crane must not be used for dragging
loads sideways.
5 Do not move loads over people.
6 Keep more than five full wraps of rope on the winch drum.
7 While in transit, take the following additional precautions:
a) Position the crane boom in line with the direction of motion of the truck.
