A counterweight device and operation machinery. The counterweight device comprises a main counterweight (2) and a secondary counterweight (3), which are independently arranged, wherein the main counterweight and the secondary counterweight are both connected to a rotary table (1), and the secondary counterweight is located on the side of the main counterweight facing the rotation center (12) of the rotary table. The hoisting capacity of a crane can be fully guaranteed by means of the main counterweight and secondary counterweight; and the secondary counterweight is separately mounted on an inner side of the main counterweight, such that the main counterweight can be separately detached, and the secondary counterweight cannot go beyond the crane during transferring, and therefore the problem of there being great difficulty in terms of detachment of the overall counterweight is avoided, road transportation requirements are satisfied, the operation is convenient, and performing transferring is facilitated.

    Dispositif de contrepoids et machine d'exploitation. Le dispositif de contrepoids comprend un contrepoids principal (2) et un contrepoids secondaire (3), qui sont agencés indépendamment, le contrepoids principal et le contrepoids secondaire étant tous deux reliés à une table de rotation (1), le contrepoids secondaire étant situé sur le côté du contrepoids principal faisant face au centre de rotation (12) de la table de rotation. La capacité de levage d'une grue peut être complètement garantie au moyen du contrepoids principal et du contrepoids secondaire ; et le contrepoids secondaire est monté séparément sur un côté interne du contrepoids principal, de sorte que le contrepoids principal peut être détaché séparément, et le contrepoids secondaire ne peut pas dépasser la grue pendant le transfert. Par conséquent, le problème d'une grande difficulté en termes de détachement du contrepoids global est évité, les exigences de transport routier sont satisfaites, l'exploitation est pratique et la réalisation d'un transfert est facilitée.

    一种配重装置及作业机械,配重装置包括相互独立设置的主配重(2)和副配重(3),主配重和副配重均与转台(1)相连接,且副配重位于主配重朝向转台回转中心(12)的一侧。通过主副配重能够充分保证起重机的吊载能力,同时将副配重单独置于主配重内侧安装,主配重可单独拆下,副配重在转运时不会超出车外,避免配重整体拆除难度大的问题,满足道路运输要求,操作便捷,便于转运。
