Pull wire switch for safe mining conveyor systems

Electric Control Products offers the SAFE-T-PULL pull wire switch, which has been tested to the requirements of AS 1755-2000. Tripping occurs if one or both trip wires are removed, overtensioned or activated, or a manual trip can be triggered via the reset knob.

The SAFE-T-PULL pull wire switch provides absolute simplicity in initial set-up and adjustment, and has the following design features:

• Robust non-metallic enclosure
• Low-maintenance design
• Stainless-steel internal compression type springs
• 316 stainless-steel pull rods
• Pull rods have external dust-protecting boots for seal protection
• Double-lip oil seals on pull rods and reset operator for secure dust and weather protection to IP 67
• Non-metallic pull rod bushings
• Positive drive action from cams through to switching contacts provides mechanical forcing of the trip contacts
• Internal switch connections are fully shrouded for added safety during inspection
• Cam design compensates for pull wire expansion / contraction up to 30mm either side of the set point; eliminates nuisance tripping due to vibration

Mining conveyor belt misalignment switch

Electric Control Products offers the heavy-duty SAFE-T-DRIFT conveyor belt misalignment switch for customers requiring a unit that caters for high-speed belt applications, having a pre-warn trip contact and a final trip contact.

Dual operation (right hand / left hand) is also available with SAFE-T-DRIFT. Its unique spring / cam operator ensures long, trouble-free operation in the most severe environmental situations.

Robust conveyor belt misalignment switch unit

The conveyor belt misalignment switch unit is made from a robust, glass-filled nylon 66 non-corrosive enclosure according to IP67, and all external fixings are constructed from 316 stainless steel.

In addition it has mineral-filled nylon operating shaft bearings for long maintenance-free operation, operating shaft sealing via a double lip oil seal, with external dust protecting boot, and 90° full movement of operating arm with easily adjustable switching points from 5° to 75°.

The switch has solid or sprung shaft roller mounting arms, available either vertical or horizontal. The roller arms are made from 50mm diameter stainless-steel with high-speed sealed ball bearings. Arms are fully adjustable through 360°.

Conveyor belt tear detector

Electric Control Products offers the SAFE-T-RIP heavy-duty belt tear / rip detector, which is magnetically operated, utilising the inherent reliability of Reed switches. The Reed switches are encapsulated in a robust, non-metallic enclosure.

Features of the conveyor belt tear detector include:

• Robust glass-filled nylon 66 non-corrosive enclosure to IP67
• 316 stainless-steel external fixings
• Dust boot on socket assembly
• Socket mounted on either side, top or rear of enclosure
• Two 20mm stainless-steel armoured cable glands available
• Two 20mm conduit entries
• Label attachment lug on lid
• Switches pre-wired to terminals

Mining conveyor lanyard emergency-stop pull wire signs

The SAFE-T-PULL SIGN is a highly reflective emergency-stop sign for conveyor lanyard switches and pull wires. It is manufactured from a high-grade 3M reflective product, which has a ten-year guarantee and is mounted to a specially designed mounting bracket, angled to give the operator a view of the sign at all angles.

The angle is designed so that when mounted as per the Australian standard AS1755-2000 (every 30m), they can be seen at every 15m point. The Australian standard AS1755-2000's clause 2.9.4 (c) states that signs shall be provided at each end and every 30m along a conveyor where a pull wire is used, e.g. for an emergency stop. The PULL SAFE pull wire switch complies with the requirements of AS4024 Parts 1 and 2.

Lanyard pull wire guide

The SAFE-T-GUIDE (STG-200) is made from UV-stabilised polypropylene, non-corrosive material mounted on a M10, 200mm long galvanised steel support rod P/N STG-200. A stainless-steel support rod for the lanyard pull wire guide is also available.

The STG-200 has a 50mm long rope guide surface and a 24.5mm diameter tunnel with belled ends. The STG-200 is suitable for pull wires from standard 3mm PVC-coated wire rope, through to larger communication cables.
