Chapter 8 Crane operation
In case of emergency
In case of emergency stop all crane movements immediately (refer to chapter 5, 'Emergency cut-off
button').
Lowering the load
Danger! In cranes without overload protection system, the load
lowers uncontrollably when the permissible load moment is exceeded.
Refer to chapter 5, 'Capacity indicator'.
Don't increase the outreach when lowering the load.
If you increase the outreach when lowering the load, the load may lower uncontrollably.
Monitor the capacity indicator.
Landing the load
The landing area must be free of obstacles.
Don't land the load on ice or snow.
Don't land the load on drop offs, bumps, slopes, holes, ditches, etc.
Land the load only on solid level ground; if necessary use suitable blocks or boards.
When the load is put down, the load on the main boom must not be relieved suddenly.
Warning! If the load on the main boom is relieved suddenly, bulk
materials are emptied quickly (grab application) or the load is put
down quickly with the cable winch, the main boom may snap upwards.
Always put loads down slowly.
Before detaching the load lifting gear make sure the load sits properly and stable.
