General Purpose gantry hook crane (KK)

The general purpose gantry hook crane is characterized by a flexible suspension of the load-gripping device. The load-gripping device used is hooks according to GOST 6627, GOST 6628 and GOST 6619, as well as special hooks in accordance with the customer's design documentation.

The gantry crane is designed as a span structure in which the span structures move along rails laid on a concrete foundation. The design of the gantry crane consists of a single-girder or double-girder bridge with one or two consoles, or without consoles. Single-girder bridges of triangular and tetrahedral cross-section with a driving monorail are widely used. The span beams of double-girder bridges are similar in design to the beams of overhead cranes.

The spatial pillars of rigid supports of gantry cranes are made triangular or tetrahedral, while their belts are connected with diaphragms or gratings to ensure rigidity. The mechanisms of movement of general-purpose gantry cranes are made with separate support drives.

The drive of the cargo lifting and trolley movement mechanisms can be installed directly on the cargo trolley (self-propelled trolleys) or permanently on the bridge (trolleys with rope traction). If necessary, the cargo trolley is equipped with a hook traverse and an electric hoist for auxiliary lifting.

In cranes with higher lifting capacity, monorail or double-rail, rope and self-propelled trolleys are used. Double-rail trolleys can be suspended or supported, moving along rails laid on the upper chords of the bridge beams.

All crane mechanisms are controlled from the control cabin, and all crane mechanisms operate using individual drives for all working elements. For large spans, when the operator's observation of the crane's operation is difficult, the cabin is made to move together with the cargo trolley.

The control system using starting and control electrical equipment allows for control of the speed of crane operations, in particular: crane movement, movement of the cargo trolley, and raising and lowering of the hook.

When assembling crane units, we take into account the technological specifics of the customer's production, as well as individual requirements reflected in the technical specifications for the crane. When producing a general-purpose gantry hook crane, we use components from leading manufacturers and trusted suppliers.
