Safety Guidelines
Operator’s Manual for Crawler Crane
3.7 Snow and ice
(1) Danger of accidents (due to chunks of ice breaking off and falling down).
(2) Increased danger of damage due to frozen height limit switches on main boom and
jib.
Precautions:
– Lay down the boom and carefully knock off the ice that has collected.
– Carefully remove the ice from all sensitive parts, such as limit switches, guides, etc.
Snow and ice deposits on the boom:
(1) Increase the boom weight
(2) Increase the surface area the wind blows on.
These factors can lead to a premature shutdown of the movement of the crane. Work
can continue, but definitely not at the maximum permitted load.
The load moment limiter (usually abbreviated to LMI)
(1) Must only be triggered in an emergency.
(2) Cannot be used in normal operations as a device shutting down the crane.
(3) Is not a substitute for judgment of the crane operator.
