Abstract

The utility model discloses a hoisting equipment, especially a crawler crane with crawler-type super balance weight dolly. Including with the super mast that rises of host computer revolving stage round pin hub connection and with surpass the super counter weight arm-tie that rises mast top and meet, its characterized in that: the lower end of the super-lift counterweight pulling plate is connected with a crawler-type super-lift counterweight trolley with a counterweight block. Because the balancing weight is arranged on the crawler-type super-lift balancing weight trolley, the crawler-type super-lift balancing weight trolley not only can conveniently walk along with the whole crawler-type super-lift balancing weight trolley, but also greatly reduces the grounding specific pressure, enhances the practicability and further improves the operation and operating environment of the crawler crane.

Description

Crawler crane with crawler superlift counterweight trolley

technical field

The utility model relates to a lifting device, in particular to a crawler crane with a crawler-type super-lifting counterweight trolley.

Background technique

With the development of crawler crane technology, the conventional superlift counterweight as a key component brings inconvenience to the whole machine. At present, there are two main forms of superlift counterweight, one is the suspended superlift counterweight, that is, in the superlift counterweight The top of the mast is connected with a superlift counterweight pull plate, and the bottom of the super lift counterweight pull plate is connected with a counterweight. The counterweight is located on the ground during normal lifting. If it is necessary to walk, the counterweight must be lifted to use Only when it leaves the ground can the whole machine walk, which is troublesome to operate and inconvenient to walk. The other is to place the counterweight on the tire-type trolley. This super-lifting counterweight has the disadvantages of high ground specific pressure and a large vertical load on the tires.

Contents of the invention

The purpose of the utility model is to provide a crawler crane with a crawler-type superlift counterweight trolley which has a small grounding specific pressure of the superlift counterweight, is simple to operate, and is convenient to walk, so as to overcome the deficiencies of the prior art.

The crawler crane with crawler-type super-lifting counterweight trolley of the utility model comprises a super-lifting mast connected with the pin shaft of the main engine turntable and a super-lifting counterweight drawing plate connected with the top of the super-lifting mast, and is characterized in that: The lower end of the heavy-drawing plate is connected with a crawler-type super-lifting counterweight trolley with a counterweight.

The utility model is a crawler crane with a crawler-type super-lifting counterweight trolley, wherein there is a connecting frame connected by a pin shaft above the crawler-type super-lifting counterweight trolley, and the described counterweight is arranged above the connecting frame.

The crawler crane with crawler-type super-lifting counterweight trolley of the utility model, because the counterweight block is placed on the crawler-type super-lifting counterweight trolley, not only can walk with the whole machine conveniently, but also greatly reduce the grounding specific pressure, The enhanced practicability further improves the working and operating environment of the crawler crane.

Description of drawings

Fig. 1 is a schematic structural view of a specific embodiment of the utility model.

Detailed ways

As shown in Figure 1: 1 is the super-lifting mast whose pin shaft is connected on the turntable of the crawler crane, the super-lifting counterweight pull plate 2 is connected above the super-lifting mast 1, and the bottom of the super-lifting counterweight pull plate 2 is connected with a belt The crawler-type super-lifting counterweight trolley 3 of the counterweight 5, the specific connection structure is: the ordinary crawler walking mechanism is selected, and the connecting frame 4 welded by metal section steel is connected to the top of the frame body through the pin shaft, and the top of the connecting frame 4 is according to Several counterweights 5 need to be stacked on top of each other. The super lifting counterweight pull plate 2 can be connected with the frame body above the connecting frame 4 or the crawler track traveling mechanism by a pin shaft. In order to simplify the structure, the drive of the crawler walking mechanism can be driven by an engine, and the power of the engine can be used to drive the walking through a coupling and a hydraulic mechanism, etc., and remote control can also be realized.
