Embodiment Construction

[0023] The present invention is further described below in conjunction with embodiment:

[0024] The invention discloses a dual-purpose crane, which can realize the replacement of two different cranes by only changing the jib unit and sharing the turntable and getting off the vehicle. The dual-purpose crane can save a lot of purchasing costs and create considerable economic benefits.

[0025] Specifically, the dual-purpose crane includes a crawler telescopic boom crane boom unit, a crawler crane boom unit, a turntable, and an alighting vehicle;

[0026] The turntable is connected to the vehicle through a slewing support; the structure of the vehicle is as follows figure 1 As shown, including frame, track frame, track, drive wheel, track roller, guide wheel and drag chain wheel. The boom unit of the crawler telescopic boom crane includes a telescopic main boom, a main boom luffing cylinder, and an auxiliary hoisting winch. The boom unit of the crawler crane includes the main...

Abstract

The invention provides a double-purpose crane. The crane comprises a caterpillar band telescopic arm crane arm rest unit, a caterpillar band crane arm rest unit, a rotary table and a lower crane. The rotary table is connected with the lower crane through a rotary support, and hinge points which are matched with the caterpillar band telescopic arm crane arm rest unit and the caterpillar band crane arm rest unit are arranged on a rotary table frame; and function replacement of the double-purpose crane can be achieved through replacement of the caterpillar band telescopic arm crane arm rest unit and the caterpillar band crane arm rest unit. The double-purpose crane is simple in structure, reasonable and compact. The rotary table and the lower crane are used in common, a user only needs to replace an arm rest unit, and rapid replacement of two different cranes can be achieved.

Description

technical field [0001] The invention relates to engineering hoisting machinery technology, in particular to a dual-purpose crane. Background technique [0002] In the construction crane industry, in order to meet the needs of different harsh working conditions, people usually buy crawler cranes or crawler telescopic boom cranes for hoisting operations. Both models have their own advantages. Both purchases require considerable capital. The crawler telescopic boom crane is similar to the crawler crane in the form of getting off the car, the layout of the turntable is slightly different, and the form of the jib is completely different. Whether the two types of cranes of equivalent tonnage can share the turntable and the unloading part, the customer only needs to replace the jib to realize the functions of the two types of cranes. Contents of the invention [0003] The purpose of the present invention is to propose a dual-purpose crane for the high cost of purchasing crawle...
