Overload limiter introduction

Overload limiter for material handling equipment is the necessary device to prevent crane accidents caused by dangerous operation of lifting weight exceeding the rated lifting capacity of the material handling equipment. The overload limiter contributes greatly to the safety of lifting equipment and operation staffs.5YIHenan Dongqi Machinery Co., Ltd

Components of overload limiter

The weight overload limiter is mainly consisted of sensor, computing amplifier, controlling actuator and load editor etc. And also the weight overload limiter is equipped with displayer, controller, and alarm for the sake of convenient operation.5YIHenan Dongqi Machinery Co., Ltd

Work principle of overload limiter

How does the weight overload limiter work? Generally, during crane operation, the sensor deformation transforms loads weight into electric signal which will be amplified through computing, and then the loads weight will be calculated out and displayed. When the loads weight reached 90% of the rated weight, warning signal will be emitted. And the power source of material handling equipment will be cut off when loads weight exceeds that of the rated to ensure the safety operation of the equipment and operators.5YIHenan Dongqi Machinery Co., Ltd

Applications of overload limiter

Overload limiter is widely used on cranes and hoists. Generally, the overload limiter takes force from crane lifting mechanism, sends feedbacks to the instrument by collecting, calculating, contrasting and judging and finally displays the current weight and indicates the corresponding condition. When the load exceeds the rated weight, lifting circuit of crane hook will be cut off immediately to keep the crane and operator from dangers.5YIHenan Dongqi Machinery Co., Ltd
