Abstract

The invention relates to an installation method and a device of caterpillar crane mast. The installation method comprises the following steps: connecting the bottom end of a mast with the pivot of a crane platform; respectively installing a standing block and a running block on the crane platform and the mast; arranging a hoister on the platform; fixedly connecting the hoister with one end of a steel wire, and fixedly connecting the other end of the steel wire with the platform by orderly winding around the standing block and the running block; pulling the mast up around the pivot by the hoister through the driving of the standing block and the running block, and successively fixing an anti-slantwise oil cylinder and a mast bracket on the mast at installation positions on the platform during the process of pulling so as to finish mast installation. The invention has the advantages of rapid and effective installation, no need of the hoisting operation of a crane, safe and controllable operation and time saving.

Description

technical field [0001] The invention relates to the field of crawler cranes, in particular to a method and device for installing an upper mast of a crawler crane. Background technique [0002] The current crawler cranes are large in size and heavy in weight, so it is very inconvenient to install the mast on the crane platform in place. Usually, the installation method of the mast is: lift the mast assembled on the ground to the top of the platform by a crane, and use another The crane adjusts the angle of the mast, and then installs it in place. The whole installation process requires high operation and is time-consuming, so a safe, convenient and effective installation method is needed. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method and device for installing a crawler crane mast, which makes the installation of the crawler crane mast more convenient, effective and safe. [0004] In order to achieve the ab...
