The 53 K with its benefits
Flexible is efficient
 Fast climbing up to 3 tower sections
 7 different horizontal hook heights
 4-way adjustable jib from 28.0 to 40.0 m
 20° raised jib position

MICROMOVE:
Millimetre precise positioning
With MICROMOVE, at the push of a button on the control
lever, lowering speed is reduced to micro levels. Even the
heaviest loads can be precisely suspended and positioned
without using the hoist gear brake.
Pure rope erection
The complete erection process is
completed using a well designed,
low maintenance erection kinematics
system with rope.
Wind load control
The control reacts automatically to the
counter torque on the jib for safe working
in the wind.
Fast climbing
Up to 3 tower sections can be inserted to
reach hook heights of up to 43.1 metres.
Current collector
No restrictions with slewing,
no wound cables.
Load swing damping
Automatic compensation of jib move-
ments for static load.
Automatic reeving device
Adjustment from 2 to 4-line mode
with no complicated resetting.
