5 WORKING WITH THE CRANE
5.1
GENERAL INFORMATION
The safe and effective use of the device requires good knowledge of the device and extensive
practical experience. Each crane model has different trajectory, speed and characteristics, so even
experienced users are encouraged to thoroughly acquaint themselves with the operation of the
new crane before its actual commissioning.
5.1.1 Safety instructions
Please read and understand the operation, maintenance, and safety in-
structions before operating or servicing the cranes. Operation, mainte-
nance and adjustment may only be carried out by people qualified for
operating and servicing the specified device. Lack of information on the
device's operation and characteristics can cause serious injury or death.
The user must always wear safety equipment
such as a safety helmet, protective clothing, safety footwear,
hearing protection, safety glasses and other protective equipment.
It is forbidden to use the crane unless the use and safety instructions have been studied!
* Always apply parking brakes for the time of loading. If necessary, place blocks in front of wheels.
* Check that the rear mounting bracket has been locked to the vehicle with a chain
* Stabilizer legs are operated from a valve attached to the base or from the control position by re-
mote control.
* Spread out the stabilizer legs as wide as possible to achieve good standing stability. If this is not
possible, start loading with small loads.
* Make sure that the ground under the stabilizer legs is strong enough. If necessary, use additional
plates.
* The stabilizer legs are fitted with lock valves, so they hold in case of a possible overload or hose
failure. The stabilizer legs are prevented from turning by pin locking, if necessary. (For example, a
stand-mounted crane is removed from the truck to its stabilizer legs). Pin locking cannot be used
during working.
* Please note that when the load increases, most of the weight goes to the stabilizer legs because
the truck springs have been lightened by stabilizer legs. As a result, it is recommended to shorten
the stabilizer legs in the mid of loading, in which case the weight shifts to the truck wheels.
* Avoid loading on a sloping surface. If this is not possible, use extreme caution and lift small loads.
When loading uphill, please remember that the pressure relief valve of reversing cylinders can be-
come overloaded and the load can escape downhill and cause an incident.
