With the development of economy and the continuous progress of science and technology, the crawler technology in China is continuously developed forward. The crawler type construction machine has a larger contact area between the crawler and the ground than the tire type construction machine, and thus has a smaller average pressure on the ground. About 0.05-0.25 MPa can be used for working on soft and muddy ground. The traction coefficient of the wheel-type engineering machinery is high, about 1.5 times of that of the wheel-type engineering machinery, the climbing gradient is large, and the wheel-type engineering machinery can run on rugged fields. Because the crawler-type engineering machinery has wide bearing surface, the stability is good, and a supporting leg device is not required to be arranged on the crawler-type engineering machinery like a wheel mussel type engineering machinery. For large-scale crawler-type engineering machinery, in order to improve the stability during operation, the crawler device is designed to be transversely extendable so as to enlarge the supporting width, which is not sufficient for the wheel-type engineering machinery. Therefore, the crawler belt is continuously applied to engineering machinery and military products.
How to install the crawler belt on a production line is investigated, and paving and installing the crawler belt by various crawler belt manufacturers are carried out by means of commands of traveling cranes and field operators. The method specifically comprises the following steps: the final procedure of the crawler-type engineering machinery on a general assembly line is to install a crawler. At present, when a crawler is installed by various crawler engineering machinery manufacturers, a crawler with the length of several meters is hoisted by a crane, and a crane responsible person moves the crane according to gestures of ground operators to flatly lay the crawler on a crawler installation lifting platform. And moving the production line to enable the machine to be placed on the crawler belt, and finally installing the crawler belt by means of the travelling crane and a crawler belt installation tool.
This process not only has unsafe factors but also requires a specially-assigned person to operate the vehicle and the cooperation of the vehicle operator and the ground operator. For example, after a crawler with the length of several meters is hoisted by a high crane, the proper position for paving the crawler is realized by the feeling and experience of field operators, and great unsafe factors and uncertainty exist.
