The Tolsma-Grisnich conveyor belt is constructed with a stable frame composed of flat sections. The rubber or plastic belt is enclosed within this frame, and is fully supported by trough rollers and/or idlers. The trough rollers and/or idlers are fitted at a 500mm centre distance by means of a maintenance-friendly bolt/pitch connection.
The return rollers with rubber rings are fitted at a centre-to-centre distance of 2000mm. The drive drum is crowned and coated with a 6mm chequered rubber profile. The tension roller is also crowned and fitted with a continuous shaft. Crowning of the drums improves the tracking of the rubber belts, as well as reducing belt wear and tear.
Both the driving and tightening side can be adjusted by means of a simple turning movement using the unique tensioners.
