Truck crane
Operating Manual GMK6300L
The number of reeved rope lines must be selected such that the load on the
hoist rope does not exceed 50% of the rope pull. At the same time, the total
weight of the lifted load must be considered, consisting of the weights of the
hook block, the lifting gear and the equipment for lifting persons including
the maximum payload.
When transporting persons, the crane operator must maintain the safe dis-
tances from overhead power lines applicable in the country in which he is
working. The distances are normally greater than the distances for lifting
loads specified in the Safe distance from overhead power lines section.
The person being transported must be in radio contact with the crane
operator.
When used for transporting persons, the truck crane must not be used for
other tasks.
The crane operator is not permitted to exceed the maximum permissible
wind speeds and wind loads for transporting persons applicable in the
country in which he is working. These values are normally lower than those
for lifting loads specified in the lifting capacity table .
When the equipment for lifting persons is being used and is in a stationary
position, then the slewing gear, hoist, derricking gear and telescoping
mechanism must be secured against accidental use by being switched off.
The truck crane must be equipped (e.g. with hydraulic emergency opera-
tion) so that the equipment for lifting persons can be set down and the per-
sons being transported can safely leave it even if there is a failure of the
drive or crane controls.
The hook that holds the lifting gear for the equipment for lifting persons
must be fitted with a lockable latch that completely seals the hook opening.
The truck crane must be serviced as prescribed, regularly inspected and
repaired, if required. All safety stickers must be affixed in their appropriate
places and be legible.
