Problems solved by technology

The hoisting mechanism is generally installed above the running trolley. Due to the neglect of the height limit of the top space in some factories, when installing the crane, they encountered the problem of interference between the crane trolley frame and the steel structure of the factory building, which could not meet the installation needs; if lowered The installation of the track height of the double-girder crane will cause a large loss in the lifting height of the double-girder crane used, which will bring great inconvenience to the user enterprise
[0003] It is difficult to modify the structure of the factory building, and the workload is heavy. Therefore, the height of the whole machine can be reduced by installing the lifting mechanism on the lower part of the trolley frame, but this method makes the space for the hoisting mechanism in the trolley frame smaller, giving Inconvenience caused by maintenance

Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing:

[0012] A double-girder crane, comprising a trolley (1), a lifting mechanism (2), the hoisting mechanism (2) is installed on the lower part of the trolley (1), and is characterized in that a telescopic hydraulic cylinder (3 ), the lifting mechanism (2) is set on the telescopic hydraulic cylinder (3).

[0013] Adjust the position of the lifting mechanism through the telescopic hydraulic cylinder so that its height is lower than the height of the factory building, and adjust the lifting mechanism as high as possible to facilitate maintenance.

[0014] The height of the whole machine is reduced in the present invention, which can be applied to various workshop environments and reduces the limitation on the height of workshops.

Abstract

The invention provides a two-beam bridge crane which is not easily limited by the plant height and is convenient to maintain. In order to solve the technical problems, the two-beam crane provided by the invention comprises a trolley and a hoisting mechanism, wherein the hoisting mechanism is mounted at the lower part of the trolley; a telescopic hydraulic cylinder is arranged on the lower end surface of the trolley; and the hoisting mechanism is arranged on the telescopic hydraulic cylinder. The position of the hoisting mechanism is adjusted through the telescopic hydraulic cylinder so that the hoisting mechanism is lower than a plant; and the hoisting mechanism is elevated as much as possible to facilitate maintenance. With reduced overall height, the two-beam crane provided by the invention can adapt to multiple plant environments, and the limit of plant height is reduced.

Description

technical field [0001] The invention relates to a crane, in particular to a double-girder bridge crane. Background technique [0002] Universal bridge cranes are widely used in various types of workshops, workshops and warehouses due to their large carrying capacity and good stability. The hoisting mechanism is generally installed above the running trolley. Due to ignoring the height limit of the head space in some factories, when installing the crane, they encountered the problem of interference between the crane trolley frame and the steel structure of the factory building, which could not meet the needs of installation; if lowered The track height of the double-girder crane is installed, and the lifting height of the double-girder crane used is greatly lost, which brings great inconvenience to the user enterprise. [0003] It is difficult to modify the structure of the factory building, and the workload is heavy. Therefore, the height of the whole machine can be reduced ...
