Abstract

The invention relates to hoisting equipment, in particular to a rubber-tyred gantry crane with a suspension crane and a construction method thereof. The crane consists of a gantry and a hoisting device arranged on the gantry, wherein a walking mechanism is arranged at the lower part of the gantry; a balancing weight block is arranged at the rear end of the gantry which is also provided with a generating unit and an electric control device which are connected with the hoisting device and the walking mechanism; the rubber-tyred crane is novel hoisting equipment which combines cranes of tyre type, gantry type and suspension arm type; the rubber-tyred walking mechanism ensures that an LTD10 type crane has more flexible forward, backward and steering and wide running range and is not limited by tracks; the steering mechanism adopts an electric push rod as steering power, has sensitive reaction and is beneficial to improving the operation efficiency; a gantry structure has favorable stable performance, small volume, can be integrally transported and is convenient to install on site; and in a winch mechanism of the rubber-tyred crane, an electric hoist with mature technology is used, so that the manufacturing construction period and the cost can be saved.

Description

technical field

[0001] The invention relates to a lifting device, in particular to a rubber-tyred gantry crane with a cantilever crane and a construction method thereof. Background technique

[0002] At present, the lifting equipment often used in the field of construction machinery is tire type, gantry type, cantilever type, etc. Among them, although tire type cranes are convenient in transportation and flexible in steering, they are not flexible enough when lifting heavy objects. And the load capacity is not large enough; while the gantry crane has good stability, but it has a big defect in the flexibility of transportation; due to the limitations of its installation, the cantilever crane is not flexible enough in construction, especially in the installation of construction frames. To sum up, these kinds of lifting equipment bring different degrees of problems to construction in different fields, which need to be solved urgently. Contents of the invention
