Product description

Exhibitor Profile

Floor Plan

4B's Touchswitch is an electro-mechanical limit switch with no moving parts, which detects tracking and misalignment problems on bucket elevators and conveyors. When a belt misaligns or a pulley moves over and contacts the sensor, the built in solid-state electronic circuitry detects the lateral force of the belt or pulley and activates a voltage free solid state relay output. This output signal is used to immediately alarm and ultimately shutdown the machine.

The face of the sensor is made from hardened and annealed stainless steel, not soft brass or aluminium, so wear life is longer when a belt contacts it. The Touchswitch is not affected by dust or material build up and will still work when completely covered by material. An external test wheel allows for quick and simple sensor/system testing. The sensors are usually installed in pairs on opposite sides of the machine. The sensors can be connected directly to a PLC input, or for greater safety, to a central independent monitoring system, such as Watchdog Super Elite or IE-Node.

An international market leader in the field of bucket elevator and conveyor components and electronic monitoring equipment, 4B has a long history in serving the bulk material handling industries.

4B Group has the world’s largest range of steel and plastic elevator buckets, from the popular low-profile (Super) Starco and CC-S elevator buckets, to the bottomless Spidex buckets, the traditional range of deep drawn elevator buckets, through to AA and MF Nylathane industrial duty elevator buckets.
4B offers a free design service for bucket elevators to help customers with the design of new bucket elevators or to increase the capacity of their existing elevator.
4B is also the leading supplier of elevator bolts; all the original Ref 70 Bolts, Euro Bolts (Din15237), Easifit bolts and Fang bolts are manufactured at the company’s UK headquarters. 4B’s high stock volumes mean quick delivery times.
4B’s range of elevator buckets and bolts is complemented by a complete range of elevator belting, which can be supplied slit and punched to customer specifications. 4B’s NBR and SBR low-stretch elevator belts are popular with a lot of industrial customers and elevator manufacturers for their high quality. 4B also supplies specialised elevator belting such as FDA belts and steel web elevator belting for heavy duty applications.

4B also manufactures its own range of forged conveyor chains for chain conveyors. 4B’s forged chains are suitable even for heavy duty and highly abrasive applications. 4B's superior heat treatment technique provides the optimum forged chain link with a more resilient ductile core for shock resistance, and an extremely hard exterior surface for superior wear resistance.
4B’s Bolt-N-Go system for drop forged and round link conveyor chains is becoming ever more popular with customers for its flexibility, reliability and low maintenance. The Bolt-N-Go system uses bolt-on flights instead of welding. The chain no longer needs to be removed from the conveyor for repairs, thus reducing maintenance costs and down time

4B’s electronic division specializes in level controls, electric sensors and safety control systems that prevent costly downtime and reduce the risks of explosions in hazardous areas. With an extensive range of ATEX/IECEx/CSA-approved hazard monitoring systems, misalignment switches, bearing temperature monitors, speed switches, blocked chute detectors and level indicators, 4B can offer anything from a replacement sensor to a fully integrated hazard monitoring system, that can be operated either as a stand-alone system or connected to a PLC.

4B engineers can recommend the right sensors and monitoring systems to protect any bulk handling facility, no matter if it is just a single elevator or a complete installation consisting of many elevators and conveyors. Offering a scalable solution starting with correctly chosen equipment and systems that can be expanded at a later date to encompass other machines in the plant.
4B also provides installation service and after-sales technical support to help customers overcome any technical problems with their monitoring equipment.

With over 1,000,000 sensors installed worldwide, 4B components have become an integral part of conveying systems throughout the bulk handling industry and many of its products are well known: e.g. the Watchdog Elite bucket elevator / conveyor monitoring system, the Touchswitch belt and pulley alignment sensor, the Whirligig universal shaft sensor mount, to name just a few.

With over 130 years of engineering experience in the bulk handling industry and subsidiaries on all continents along with a worldwide network of distributors, 4B can provide practical solutions for any application no matter the location, improving the safety and efficiency of bulk handling applications all over the world.
