The invention discloses a light hoisting machinery weight limiting device which is a safety protection device special for a light crane and is small in size, light in weight, convenient to install and low in cost. The device is mainly used for electric hoist cranes of various models and specifications. The device realizes weight control by controlling the magnitude of current through the current transformer and the hoisting capacity limiter, has the functions of overweight alarm and cutting off a crane overweight loop power supply, and can avoid equipment and human injury accidents caused by overload of hoisting equipment. The device is simple and reliable in structure, and can be transformed on the basis of the existing light hoisting machinery, so that the existing light hoisting machinery meets the requirement that the national hoisting machinery must be provided with a limited weight, and the cost is effectively saved for enterprises.

    本发明公开了一种轻型起重机械限重装置,是轻型起重机专用的一种安全保护装置,它体积小,重量轻、安装方便、成本费用低。主要用于各种型号规格的电动葫芦起重机。该装置通过电流互感器、起重量限制器控制电流的大小来实现重量控制,具有超重报警、切断起重机超重回路电源的功能,可避免起重设备因过负荷超载造成的设备和人身事故。该装置结构简单、可靠,可在现有轻型起重机械上进行改造,使其达到国家起重机械必须设置限重的要求,有效为企业节约成本。
