Belt Conveyor Protection Equipment
PULLSTOP
Compliant with International Safety standard

PULLSTOP is a switch for emergency stop when an accident occurs around belt conveyors and transport machines, similar to Pull Cord Switch. Mainly used for belt conveyors that transport raw materials (ore, coal, lime, gravel, etc.) at production sites. Furthermore, safety is ensured with four functions that consider risk assessment.

1. It can be used as an emergency stop device required by occupational safety and health regulations to prevent accidents resulting in injury or death to workers.
    
2. By pulling the wire rope from anywhere on the conveyor, the facility can be stopped immediately, minimizing damage.
    
3. It is also effective for safety measures before work. Activating the pull stop while working around the conveyor prevents the conveyor from being started by mistake. Serious accidents can be avoided.

The main features of the PULLSTOP are:

In addition to the basic function of PULLSTOP, four functions have been added in consideration of risks to increase safety.

1. Rope cut detection
    
2. With emergency stop push button
    
3. It can be stopped even if either of double limit switches
   fails.
    
4. Forced Separation Mechanism
   When the switch is welded, the weld is forcibly peeled off by a mechanical mechanism.

One unit can cover about 100m. You can reduce work load during installation and in event of an emergency.

Some emergency stop switches that use wire rope may malfunction due to the wire rope expanding and contracting due to the difference in temperature between summer and winter.

PULLSTOP has structure that pulls the wire rope from both sides of main body, which cancels out  expansion and contraction and prevents malfunction.

*For details, see the catalog and instruction manual.

If you connect wire ropes to both sides of PULLSTOP lever and attach wire ropes along belt conveyor, you can pull the wire rope from anywhere on the belt conveyor to activate the PULLSTOP and stop the equipment in an emergency. .

Decide on an installation location that avoids falling ore from conveyor or location subject to large vibrations or shocks.

Provide installation base for the PULLSTOP. It is recommended to install a cover in case of falling mines. The length of the wire rope for operation is up to 50m on one side.

The contact signal is a dry contact. Avoid direct input to motors and sequencers. In addition, "Control Category 4" can be ensured by using safety relay units instead of magnet conductors and relays.

After the ropes are stretched on both sides, fine-tune the operation levers with the included turnbuckles so that they are in the neutral position.

*For details, please refer to the instruction manual.
