摘要： A control system for a super-lifting device of a crane comprises a pressure-detecting element (21) for detecting the pressure of a variable amplitude oil cylinder and obtaining a measured pressure value, and a control element (22) for comparing the measured pressure value with the predetermined pressure value. When the measured pressure value is larger than or equal to the predetermined pressure value, the tensioning oil cylinder (23) is shortened, therefore increasing the tensioning pressure of the tensioning oil cylinder (23), reinforcing the tension of the super-lifting cable wire in the super-lifting device, and increasing the super-lifting moment applied to the main arm by the super-lifting device, which can effectively balance the pressure of the variable amplitude oil cylinder. A control method and a super-lifting device with the above control system are disclosed.
摘要翻译：一种用于起重机的超升降装置的控制系统包括用于检测可变振幅油缸的压力并获得测量的压力值的压力检测元件（21）和用于将所测量的压力进行比较的控制元件（22）值与预定压力值。当测量压力值大于或等于预定压力值时，张紧油缸（23）被缩短，从而增加张紧油缸（23）的张紧压力，增强超提升电缆线的张力在超升降装置中，通过超升降装置增加施加在主臂上的超提升力矩，可以有效平衡变幅油缸的压力。公开了一种具有上述控制系统的控制方法和超提升装置。

摘要： A crane transition assisting device, a transport trailer with the assisting device and a crane disassembling/assembling method by use of the assisting device are disclosed. The crane transition assisting device comprises a bearing frame (130) and supporting legs (110) which are mounted on the bearing frame and are equipped with a hydraulic cylinder (111) telescoping in a vertical direction. The bearing frame (130) is provided with at least two suspension arm brackets (120) arranged along the longitudinal direction of a horizontal plane and used for supporting a suspension arm. The assisting device realizes separation or combination of the suspension arm and a rotary table without an assistant lifting mechanism while disassembling/assembling a large-tonnage wheel crane so as to conveniently realize disassembling/assembling a large-tonnage wheel crane. The transport trailer with the assisting device can provides convenience for carrying a suspension arm, and the crane disassembling/assembling method by use of the assisting device can provides convenience for large-tonnage wheel crane transition.
摘要翻译：公开了一种起重机过渡辅助装置，具有辅助装置的运输拖车和使用辅助装置的起重机拆卸/组装方法。起重机过渡辅助装置包括轴承架（130）和安装在轴承架上的支撑腿（110），并配备有沿垂直方向伸缩的液压缸（111）。轴承框架（130）设置有沿着水平面的纵向方向布置的至少两个悬挂臂支架（120），用于支撑悬架臂。辅助装置在拆卸/组装大吨位轮式起重机的同时实现悬架臂和旋转台的分离或组合，而不需要辅助提升机构，从而方便地实现拆卸/组装大吨位轮式起重机。具有辅助装置的运输拖车可以为携带悬臂提供便利，并且通过使用辅助装置的起重机拆卸/组装方法可以为大吨位轮式起重机过渡提供便利。

摘要： A counterweight loading and unloading device and a movable crane have a freestanding pallet (10) with two ends whose upper end faces are used for holding a counterweight (61). The two ends of the freestanding pallet (10) are both equipped with a cavity, and at least one telescopic oil cylinder (11, 12, 13, and 14) is provided in the cavity. A fixed end of the telescopic oil cylinder is fixed with the freestanding pallet (10), and a telescopic end of the telescopic oil cylinder is coupled with a pallet lifting mechanism for lifting the freestanding pallet. The device is not limited by a planar space of a vehicle frame and a turntable height of the movable crane. An integral dimension of the movable crane is not increased, thus preventing integral dimension of the movable crane from exceeding a road traveling standard. The structure of the device is more compact, and the telescopic oil cylinder plays a role of the counterweight, thus enabling stress of the turntable to be more reasonable.
摘要翻译：配重装卸装置和可移动起重机具有独立的托盘（10），其两端的上端面用于保持配重（61）。独立托盘（10）的两端均配有空腔，并且在空腔中提供至少一个伸缩油缸（11,12,13和14）。伸缩油缸的固定端与独立的托盘（10）固定，伸缩油缸的伸缩端与用于提升独立托盘的托盘提升机构联接。该装置不受车架的平面空间和可移动起重机的转盘高度的限制。可移动式起重机的整体尺寸不增加，从而防止可动起重机的整体尺寸超过道路行驶标准。该装置的结构更紧凑，伸缩油缸起平衡的作用，使转台的应力更加合理。
