The lower flange trolley (U):

─     The hoist trolley travels on the lower flange of the main girder and is preset for different flange widths. The flange width can only be adapted to a slight extent (a few mm).

─     The wire rope hoist has eight wheels on which the entire load is distributed. This enables a larger load capacity than with a single girder travelling crane with a smaller span.

─     The wire rope hoist has four directly driven wheels and four non-driven wheels.

─     The panel is located on the side opposite to the hoist drive and serves as a counterweight.

─     The wire rope hoist covers a load capacity range of 6.3 t to 25 t.

The trolley drive:

─     The drives are designed as pole-variable rotary current motors with electromagnetic brakes and gear units.

─     The drives have a low and a high speed. The ratio of the two speeds is 1:4.

─     The drive's gear unit is a maintenance-free, two-stage or three-stage planetary gear.

The hoist drive with pole-variable hoist motor:

─     The hoist drive is powered by a pole-variable 2/12-pole hoist motor with gear unit.

─     The hoist motor features an electro-magnetically actuated spring-loaded brake.

─     The hoist drive has a slow lifting speed and a fast lifting speed. The ratio of the two lifting speeds is 1:6.

─     Using plug-in connections in the connector housing directly on the hoist drive, the hoist drive can be quickly separated from the rest of the crane’s electrics.

─     The hoisting gear features a multi-stage, helical spur gear in an alloy housing. The gear wheels run in a sealed oil bath, which ensures they remain lubricated over their full service life.

─     For further details on the pole-variable hoist drive, see the product manual “Pole-variable, modular ABUS hoist drive for wire rope hoists”.

The hoist:

─     The wire rope of the hoist is a special wire rope with a very high breaking strength. This gives it a considerably longer service life than a normal steel rope.

─     The cable guide guarantees flawless winding and unwinding of the wire rope on the cable drum. It is made of wearproof, low-friction plastic.
