CONVEYORS & MATERIALS HANDLING

Improve your efficiency using an overhead conveyor

The Railtechniek van Herwijnen Group of companies , which Stewart Gill Conveyors Ltd have been a long time member of , provides complete solutions for complex requirements in the field of materials handling . They produce a wide range of overhead conveyors and materials handling products , such as manual conveyors , chain conveyors , power and free conveyors and crane systems . For the surface finishing industry the most frequently delivered systems are Power and Free conveyors . P & F conveying systems offer a high degree of flexibility and they can be completely automated .
P & F systems are equipped with load bars to attach the products . The products can be transported through the complete process ( Power ) or stopped for buffering or treatment ( Free ) without stopping the complete system . Stewart Gill Conveyors Ltd offer a wide range of P & F systems , suitable for carrying capacities up to 9.000 kg per load bar . They specialise in systems for wet paint and powder coating lines , blasting installations , assembly lines , logistic and storage systems . A system that they offer specially for the surface-treatment industry is a dipping tank crane system . Dipping cranes transport metal products in and out of a series of pretreatment tanks .
Advantages of a Power & Free Conveyor
Compact and save design with movable parts inside the tack
Modular system with standard parts Flexible design for optimal lay-out planning
Advanced automatic control system with touch screen user interface and remote access .
Components
Different standard components are available to design the most optimal conveyor lay-out . The track sections are available as Power & Free , Free or only Power in standard or cut-to-length sections .
Bends can be horizontal or vertical . The radius of the bends is often standard . Non standard bends can be made on request .
The power chain comes in standard chain link pitches and can be fitted with open or closed bearings .
Depending on product dimensions and the conveyor lay-out the product carrier can have different trolley configurations . Using multiple trolleys the load capacity of carrier can be increased .
A Power & Free system needs a drive system . Depending on system parameters the drive mechanism can be a caterpillar drive or a screw drive unit . For safety all drive units are utilised with a torque limiter that disconnects the drive force between the drive unit and gear motor .
Stop stations are available as standard design , ATEX or high temperature for curing ovens . Stop stations are controlled and monitored by the PLC / PC control system .
Switches are installed at the position where carriers must divert to other directions . Pneumatic cylinders with position sensors are used to actuate the switches . Depending on the position in the lay-out switches can also be self-switching . Switches are also controlled and monitored by the main control system .
To avoid as much as possible wear of the chain and trolleys a lubrication unit can be used . This automatic controlled device lubricates parts such as the chain links and bearings on a pre-set interval .
Special parts are available such as lift- and drop sections , transfer chains , pneumatic pushers and product rotation units .
There are also solutions to have a dipping tank crane system take over the products from the carriers and after the dipping process hang them back onto the carriers .
