Problems solved by technology

[0002] The centerline of the main platform of the traditional crawler crane main engine generally coincides with the centerline of the slewing mechanism. In order to ensure the stability of the whole machine, the width direction of the main engine of the crane is designed to be larger. In this way, the transportation cost will be increased virtually.

Embodiment Construction

[0011] The present invention will be further described below in combination with principle diagrams and specific operation examples.

[0012] Such as figure 1 As shown, the eccentric layout structure of the crawler crane platform of the present invention is applied to the crane host 0, including the main platform 5, the slewing mechanism 9, the front counterweight and the rear counterweight 2, wherein the center of the main platform 0 The line 00 is offset from the centerline 99 of the slewing mechanism 9, and the center of gravity of the whole machine is controlled to fall on the centerline 99 of the slewing mechanism 9 through the offset between the centerline 22 of the rear counterweight 2 and the centerline 00 of the main platform 0. In this way, the stability of the whole machine can be guaranteed to be improved.

[0013] Specifically, the main engine 0 also includes a left platform 8 and a right platform 3 respectively connected to the left and right sides of the main p...

Abstract

The invention discloses a crawler crane platform eccentric arrangement structure, which is applied to a main machine of a crane. The crawler crane platform eccentric arrangement structure is characterized in that: the structure comprises a main platform, a swing mechanism, a front weight, and a rear weight; a central line of the main platform deviates from the central line of the swing mechanism; a whole crane center of gravity is controlled to fall on the central line of the swing mechanism through deviations of the central lines of the rear weight and the main platform; and the width of the main machine is equal to or less than 3 m. In the invention, the width of the main machine is limited to a certain range, so the transportation cost is reduced and the transportation reliability is improved.

Description

technical field [0001] The invention relates to the technical field of crane manufacturing, in particular to an eccentric arrangement structure of a crawler crane platform and a crane including the structure. Background technique [0002] The centerline of the main platform of the traditional crawler crane main engine generally coincides with the centerline of the slewing mechanism. In order to ensure the stability of the whole machine, the width dimension of the main engine of the crane is designed to be larger, which will increase the transportation cost virtually. Contents of the invention [0003] In view of the above existing problems, the purpose of the present invention is to provide an eccentric arrangement structure of the crawler crane platform, which reduces the width of the main engine, reduces the transportation cost, and improves the stability of the whole machine. Another object of the present invention is to provide a crane comprising the above-mentioned ec...
