Embodiment Construction

[0028] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.

[0029] An embodiment of the present invention provides a method for controlling self-loading and unloading of a crawler crane, such as figure 1 As shown, the method includes:

[0030] Step S100: judging whether the actual working condition of the crane is a self-loading and unloading working condition;

[0031] The self-loading and unloading working condition refers to the process in which the crane directly installs the track frame by hoisting on the vehicle after the outriggers are opened. Heavy refers to the weight that maintains balance by increasing its own weight. Adding m...

Abstract

The embodiment of the invention provides a self-loading and self-unloading control method and system for a crawler crane and the crawler crane, and belongs to the technical field of crawler cranes. The self-loading and self-unloading control method of the crawler crane comprises the following steps: judging whether the actual working condition of the crane is a self-loading and self-unloading working condition; and under the condition that the actual working condition of the crane is the self-loading and self-unloading working condition, performing controlling to execute self-loading and self-unloading operation. According to the technical scheme, the safety of the self-loading and self-unloading process of the crawler crane can be guaranteed, human errors are prevented, and safety accidents are reduced.

Description

technical field [0001] The invention relates to the technical field of crawler cranes, in particular to a crawler crane self-loading and unloading control method and system and the crawler crane. Background technique [0002] As a kind of lifting and handling equipment, crawler crane is widely used in construction industry, manufacturing industry and port transportation industry. Each crawler crane needs to be installed with two walking crawler frames, and the process of directly installing the crawler frames by hoisting on the vehicle is the self-loading and unloading working condition of the crane. [0003] When the crane is self-loading and unloading the crawler frame, in order to make the self-loading and unloading cylinder provide horizontal tension, the boom needs to operate at a large elevation angle, even exceeding the maximum allowable angle for normal operation. Therefore, safety accidents such as overturning may occur. [0004] In the prior art, crawler cranes do...
