In today’s quarrying industry, trained engineering resource is costly and faults on a conveyor pullkey system can result in extended and unnecessary stand time. By integrating WiPAN technology into the pullkey, the condition of the emergency stop system is transmitted wirelessly to the main control
The Minewatch HT 800 Series pull key range is designed for use in safety critical systems for controlling conveyors. Each key can therefore be used as either a Stop Switch or as a Category 2 or Category 3 Emergency Stop Switch as defined in BS EN ISO13849-I PLe.
Effective for emergency situations and routine operations alike, Davis Derby's MineWATCH range of pull cable / pull wire operated safety switches are the ideal stopping devices for all conveyor systems.
This robust belt alignment switch unit is designed to give consistent and reliable operation when used in the most demanding of environments such as the conditions encountered in mines and quarries.
The Blocked Chute Probe is a versatile sensing device with a wide range of applications in mining and the materials and bulk handling industries.
The Heavy Duty Back Spillage Detector is designed to prevent spillage of conveyed mineral around transfer points and chutes.
The Belt Alignment and Tear unit is deemed intrinsically safe to the ATEX standard. The complete transducer comprises of two identical units, one positioned each side of the conveyor to be protected.
Davis Derby MineWATCH technicians designed the Digital Belt Sequence and Slip Roller to make conveyor sequencing easy and detect belt slip. As well as preventing spillages from your conveyor system, this module can also give early warning of potential belt fires.
Flameproof/ Dual Intrinsically Safe (2x12Vdc @ 500mA each) Power Supply with 120/240v ac input (other input voltages available).
As per MINEWATCH PS21-D but including 6 Intrinsically Safe to Flameproof Interposing Relays for the control of mining flameproof switchgear.
As per MineWatch PS21-D but including an 8A/Hr battery packs to create an uninterruptible Power Supply Unit.
