Description

Single-beam crane

Technical Field

The utility model relates to a hoist and mount mechanical equipment technical field especially relates to a monospar hoist.

Background

In the technical field of hoisting mechanical equipment, the single-beam crane is widely applied to hoisting goods in different occasions such as workshops, factories, warehouses, stock yards and the like.

Currently, single beam cranes in the market are generally divided into two types: the first one is old single beam crane, the main beam is cut with angle, the end is connected with the end beam side by flange; the second type is the European style single beam crane, which puts the main beam above the end beam, supports the main beam by the end beam, and connects the main beam and the end beam by high strength bolt and positioning pin.

The single-beam cranes of the two structural forms have certain defects, wherein the old single-beam crane has a diagonal web plate of the main beam, and the hoist can interfere with the upper cover plate of the main beam when running to the extreme position of the end part of the main beam, so that the structural form can increase the left and right limits of the hoist, namely the blind area of the crane. The older single-beam crane of the European style single-beam crane has a simple structure, and simultaneously solves the problem that the traveling blind area of the older single-beam crane is larger, so that the crane is widely applied, but the whole vehicle height of the crane is increased, and in order to meet the use requirement, the height of a factory building is required to be increased, so that the construction cost of the factory building is increased.

And when the customer used the hoist of bigger rated load-lifting capacity according to actual demand, if use european style hoist can lead to headroom to increase to the height of original factory building can't satisfy the user demand.
