The new Linden Comansa 21 LC 750

The new model also tops out its LC2100 Series, whose jibs and mast sections are fully compatible with those used on the new 21 LC 750. The 21 LC 750 tower can, for example, be used on smaller models to achieve greater freestanding heights. An example of this is that the 21 LC 550 can be climbed up to 85.8 meters with fixing angles, instead of reaching 71.1 with the standard tower sections.

One of the main advantages of the new model is its simplicity of erection, as the “cat-head” has been removed. Due to this special design, the jib and counter-jib are joined together on the turntable, without any apex section. This way, assembly is easier and faster, saving money every time the crane is erected.

All versions of the 21 LC 750, feature the 110 kW hoist motor, with hoist-drum rope storage capacity of 1.400 metres. The difference between the various versions is mainly limited to the trolleys and the reeving; The 24 tonne version having two or four falls, the 36 tonne version a two or six-part reeving system, whilst the 48 ton version has four or eight part line. The reeving-change is automatic, controlled from the cabin, by means of a double trolley system.

The first two units of the 21 LC 750 have already been sold to Rentakran Ukraine, Linden Comansa’s distributor.
