Embodiment Construction

[0032] It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict. Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0033] The basic idea of ​​the present invention is: in order to solve the problems of inconvenient installation and disassembly of the mobile counterweight device of a crawler crane, cannot be matched with conventional counterweights, and cannot be used with super-lifting counterweights, the present invention provides a crawler crane mobile counterweight. The device and the crawler crane equipped with the mobile configuration device. The crawler crane mobile counterweight device uses a connecting device to connect with the free end of the crawler crane platform to facilitate the disassembly and installation of the mobile counterweight device; the mobile counterweight device is insta...

Abstract

The invention discloses a crawler crane mobile counterweight device and a crawler crane with the same. The mobile counterweight device comprises a mobile counterweight unit, a first connecting device and a second connecting device, wherein one end of the first connecting device is connected with the mobile counterweight unit, while the other end is used for being detachably connected with a platform beam of a free end of a crane platform; and one end of the second connecting device is connected with the mobile counterweight unit, while the other end is used for being detachably and respectively connected with a platform left longitudinal beam and a platform right longitudinal beam of the platform, which are close to the free end. According the invention, the mobile counterweight device is connected with the platform and is convenient for disassembly and assembly; the mobile counterweight device is arranged at the outer side of the free end of the platform, and a conventional counterweight hanging point can be reserved so as to realize the selective matching of the mobile counterweight device and a conventional counterweight; and the mobile counterweight device is completely arranged on the platform without influencing super-up counterweight mounting and can be simultaneously used with a super-up counterweight to provide a larger stable moment.

Description

Technical field [0001] The invention relates to the field of engineering machinery, and in particular to a mobile counterweight device and a crawler crane equipped with the mobile counterweight device. Background technique [0002] The rear counterweight of a traditional crawler crane is bound at the tail of the platform to provide a fixed and stable torque value to the whole machine. When the whole machine is working or the boom is lowered, the larger the torque, the more stable the whole machine; when the whole machine is installed or disassembled, too much torque will cause When the whole machine is tilted backward, the smaller the torque, the more stable the whole machine is. Therefore, for the whole machine, the torque provided by the fixed counterweight is double-sided and cannot be adjusted in time as required. [0003] At present, in order to meet the stability of the whole machine under different working conditions, crawler cranes generally use mobile counterweight device...
