多功能限制器是用于控制塔式起重机额定起重量、起重力矩和变幅幅度的装置。它容易实现力矩、重量及幅度的综合控制 ,便于同主机分离加工 ,实现配件的标准化、商品化。但目前广泛使用的多功能力矩限制器存在下述缺点 :①采用固定的曲线板 ,其曲线难以修正 ,批量生产的曲线板不
Multi-function limiter is used to control the tower crane rated lifting capacity, lifting torque and amplitude range of the device. It is easy to achieve a comprehensive control of torque, weight and range, easy to separate with the host processing, to achieve the standardization of parts, commercialization. But currently widely used multi-function torque limiter has the following disadvantages: ① using a fixed curve plate, the curve is difficult to amend, the mass production of the curve plate is not
