JW-LS系列双向拉绳急停开关

Wuhan Junwei· JW-LS series bidirectional rope emergency stop switch

JW-LS series two-way pull rope emergency stop switch

Special device for emergency stop protection of conveyor and safety protection of on-site personnel

Wuhan Junwei JW-LS series two-way rope emergency stop switch is specially developed for belt conveyor systems and is used for emergency shutdown scenarios on the conveyor site. When an emergency such as equipment failure and personnel safety risks occurs on site, the wire rope can be pulled anywhere along the line. The switch can be triggered to realize emergency shutdown across the conveyor line and ensure the safety of on-site personnel and equipment.

The product meets the special requirements of industrial safety regulations. It adopts a two-way trigger design. The left and right sides can be pulled and triggered. It is suitable for fixed installation and mobile transportation equipment. It has a high level of protection and can be used in harsh industrial environments such as mines, ports, steel, building materials. Long-term stable operation is an essential safety protection device for belt conveyors.

The product adopts cast aluminum shell + fully sealed waterproof design, built-in high-quality microswitch, action status indicator, manual reset design, convenient installation, simple operation and maintenance, and can be seamlessly connected with the conveyor control system. It is the core guarantee device for safe production of industrial conveying systems.

core technology advantages

Two-way trigger full-line emergency stop protection

The two-way pull trigger design is adopted. The left and right sides of the switch can be connected to plastic-coated steel wire ropes. The steel wire ropes are arranged along the entire line on both sides of the conveyor. The switch can be triggered by pulling the steel wire rope anywhere on site, realizing emergency shutdown of the conveyor without protective blind areas, and comprehensively ensuring the emergency safety of on-site personnel and equipment.

Visualize action status and convenient operation and maintenance

Comes with a red action sign, which automatically stands up after the switch is triggered, which can visually display the action status of the switch, allowing on-site personnel to quickly locate the fault point; after troubleshooting, press the reset handle to complete the switch reset. The operation is simple and no complex debugging is required., greatly reducing the difficulty of on-site operation and maintenance.

Fully sealed and highly protective design

The product adopts cast aluminum shell + fully sealed waterproof structure, with a protection level of IP67. It can operate stably for a long time in a wide temperature environment of-20℃~+60℃, harsh industrial scenarios such as high dust, humidity and corrosion. It has built-in high-quality micro switch, long mechanical life, stable and reliable action, and long trouble-free operation cycle.

Flexible installation for all working conditions

Belt conveyors suitable for various bandwidths and groove angles can be installed on both sides of the conveyor frame. Fixed installation and mobile conveying equipment can be adapted. It is equipped with a complete set of accessories such as special tensioners, support rings, and plastic-coated steel wire ropes. The installation method is flexible, and the number of switches can be flexibly arranged according to the length of the conveyor, which is extremely adaptable.
