Lifting appliance and front handling mobile crane with same

Abstract

The invention provides a lifting appliance and a front handling mobile crane with the same. The lifting appliance comprises an upper rotary table, a lower rotary table, a lateral displacement bracket, a telescopic main beam and a longitudinal inclination drive device, wherein the lower rotary table is pivoted to the upper rotary table, the lateral displacement bracket is connected with the lower rotary table, the telescopic main beam is in sliding connection with the lateral displacement bracket, and the longitudinal inclination drive device is arranged between a boom and the upper rotary table and is used for enabling the spreader to swing in a longitudinal swinging surface located by the boom surrounding a first pin shaft. The lifting appliance is in pivoted connection to the boom of a crane through a first pin shaft. The invention also provides the front handling mobile crane which comprises the lifting appliance.

Description

technical field [0001] The invention relates to a hoisting device, in particular to a sling and a front hanger with the sling. Background technique [0002] The existing reachstacker generally adopts such as figure 1 and figure 2 The shown spreader includes: an upper turntable 11', which is used to connect with the boom; a lower turntable 12', and an upper turntable 11' are pivoted through a rotary shaft whose axial direction is perpendicular to the ground, and under the action of a rotary motor It can rotate around the rotary axis; the side shift bracket is fixedly connected with the lower turntable; the telescopic beam includes the main beam 15' slidingly connected with the side shift bracket and the left telescopic beam and the right telescopic beam located on the left and right sides of the main beam 15'. Both ends of the beam 16' have locking devices 60' which can be locked and connected with the container. The spreader in the prior art is suitable for lifting and t...

AI Technical Summary

Problems solved by technology

[0003] However, for non-standard containers manufactured without reference to ISO standards, the length, width, and height dimensions of non-standard containers are different from those of ISO standard containers.

The spreader of the prior art is just not suitable for the lifting work of this type of non-standard container

And in some comparatively special logistic places, when field work is needed, because the field field is uneven, there are different inclinations, ground protrusions and depressions, like this, the spreader in the prior art can not adapt to field work site requirements

To sum up, the spreader in the prior art cannot be flexibly applied to different packing conditions, and the scope of use is small
