Mobile crane
Product advantages
Max. load capacity: 220 t
Max. height under hook: 101 m
Max. radius: 88 m
Electronic SPS crane control with test system
• Control of the winches, slewing gear and the luffing and
telescoping motions by the LICCON computer system (PLC
control)
• Four working motions can be performed independently of one
another
• Speeds for lifting/lowering, luffing and slewing are pre-selectable
in 5 steps
• Very short response rates at the activation of crane motions
• Hoist gear and slewing gear operate within a "closed oil
circuit". This enables very sensitive lifting/lowering of loads,
or slewing. Moreover, during lowering of the load, the potential
energy generated is not converted into heat but can be re-
employed for a second motion. This saves fuel and the oil
does not reach as high a temperature as during operation
within an open circuit.
• Functional test of all essential components by means of the
LICCON test system
