OPERATING INSTRUCTIONS (Page 2 of 3)
21. When loads which are not accurately known, are to be lifted, the person responsible for the job lift shall
ascertain that the weight of the load does not exceed the crane ratings at the maximum radius at which the
load is to be handled.
22. Always adjust the rotation handbrake.
23. The hoist rope shall not be wrapped around the load.
24. The load shall be attached to the hook by means of slings or other devices of sufficient capacity.
25. The operator shall not leave the controls while the load is suspended.
26. No person should be permitted to stand or pass under a suspended load.
27. Position end of boom directly over load. Do not attempt to drag a load; this may result in severe damage to
the crane.
28. Keep tension on the hoist line at all times to prevent the line from fouling on the drum.
29. Never place a chain link on the tip of the hook in order to lift a load with the winch.
30. Make sure the safety latch on the hook is closed before lifting a load.
31. Before starting to lift, the following conditions should be noted:
a. The hoist rope shall not be kinked.
b. Part lines shall not be twisted around each other.
c. The hook shall be brought over the load in such a manner as to minimize swinging.
d. The effect of ambient wind on the load and on crane stability.
