Problems solved by technology

The crawler crane with this structure has the disadvantage of small lifting capacity, especially in the wind power industry, it is difficult for crawler cranes to meet the requirements of long arm length, small amplitude, and large lifting capacity. Therefore, only larger types of lifting equipment can be used, which not only increases the installation cost, but also causes a waste of resources

Embodiment Construction

[0009] Such as figure 1 Shown: 8 is the main engine part of crawler crane, and main arm 7 is connected with main engine 8 pin shaft, and the upper end pin shaft of main arm 7 is connected with fixed auxiliary arm 1. The junction of the fixed jib 1 and the main jib 7 is connected with one end of the fixed jib strut 3 with a pin shaft, and the pin shaft between the other end of the fixed jib strut 3 and the upper end of the fixed jib 1 is connected with a fixed jib front pull plate 2. The upper end of the main arm 7 is connected with the main arm pull plate 6 with the pin shaft at one end of the mast 9, and the other end of the mast 9 is connected with the main machine 8 with the pin shaft. The junction of the fixed jib strut 3 and the fixed jib front pull plate 2 and the main jib pull plate 6 are pin-connected with the fixed jib rear pull plate 4 . After the auxiliary arm is fixed, the pull plate 4 is connected to the middle position of the upper half of the main arm pull pla...

Abstract

The invention discloses a crawler crane, comprising a main engine (8), a main arm (7) in pin connection with the main engine (8) and a fixed assistant arm (1) in pin connection with the main arm (7), wherein one end of a fixed assistant arm brace (3) is in pin connection with the junctional part of the fixed assistant arm (1) and the main arm (7); the upper end of the fixed assistant arm (1) and the other end of the fixed assistant arm brace (3) are in pin connection with a fixed assistant arm pulling-forward plate (2); the upper end of the main arm (7) and one end of a mast (9) are in pin connection with a main arm pulling plate (6); and the other end of the mast (6) is in pin connection with the main engine (8). The invention is characterized in that a fixed assistant arm pulling-backward plate (4) is pin connection on the position which is between the junctional part of the fixed assistant arm pulling-forward plate (2) and the fixed assistant arm brace (3) and the main arm pulling plate (6). Compared with the prior art, the invention has the advantages of large arm length and huge hoisting capacity, improves hoisting capacity and lowers usage cost on the condition of the same arm length.

Description

technical field [0001] The invention relates to a crane, especially a crawler crane. Background technique [0002] The structure of the existing conventional crawler crane is that the main arm is connected with the main arm by the pin shaft, the fixed jib is connected with the pin shaft at the upper end of the main arm, and the joint of the fixed jib and the main arm is connected with the pin shaft at one end of the fixed jib strut. The pin shaft between the other end of the jib strut and the upper end of the fixed jib is connected with the front pull plate of the fixed jib, the upper end of the main arm is connected with the main arm pull plate with a pin shaft at one end of the mast, and the other end of the mast is connected with the main engine. The pin shaft is connected, and the fixed jib rear pull plate is connected with the pin shaft between the junction of the fixed jib strut and the fixed jib front pull plate and the main arm, and the above-mentioned pull plates ar...
