HIGH PERFORMANCE
Comansa luffing-jib cranes are in demand, for high rise buildings on congested sites. To obtain the necessary high performance in material handling for high rise buildings, the new LCL-500 uses frequency controlled drives rated at 110 kW on both luffing and hoist movement.
With the Comansa frequency control, not only the maximum speed with any permissible load is possible, but also ultra-low speeds in the positioning mode. In this mode the frequency controlled system can drive thru the zero point, without applying the brake. Furthermore, for more efficiency of the system and a comfortable “feel” of the load, the control lever will adapt automatically its full control range to the given loads.
For high-rise buildings, the drum of our new 110 kW hoist winch has a standard cable capacity of 940m (3,083ft.). Optionally under consultation, a bigger drum is available with a cable capacity of 1,400m (4,593ft.). This capacity drum has been engineered for special high projects.
