Title
(EN) Telescopic Crawler Chassis and Engineering Machinery Having the Same
Abstract
(EN)

The present invention relates to a telescopic crawler chassis and engineering machinery having the telescopic crawler chassis, comprising a left crawler frame, a right crawler frame and a base, further comprising at least one hollow left sliding beam and at least one right sliding beam. One end of the hollow left sliding beam is fixedly connected with the left crawler frame, and one end of the right sliding beam is fixedly connected with the right crawler frame. At least one hollow sliding seat is arranged on the base, one end of the hollow left sliding beam is movably inserted into an hollow sliding seat from the left end of the hollow sliding seat, and one end of the right sliding beam is movably inserted into an hollow sliding seat and also into the hollow part of the hollow left sliding beam from the right end of the hollow sliding seat. The change or conversion of the state of the engineering machinery can be more convenient, and the whole machine walks and operates more stably, safely and reliably.
