Solutions for special situations
The right extras for your special task
Changes in direction via turning stations, variable emptying systems for optimum discharge, or cleaning systems for viscous material – Schrage has already thoroughly conquered many problems. We are all too happy to receive new challenges from our clients – whether it involves building an entire new plant or delivering an essential spare part as fast as possible
Depending on the properties of the bulk material, different shut-off systems are available. The highest priority is given to optimum residual discharging and a design that is free of dead space.
Several options, such as vibration, spray, or rinsing systems are available for forced discharge.
A part of the tube opens toward the bottom. Optionally, the chain can be exposed to spray, vibration, or rinsing systems from above.
This is the most inexpensive solution if dead space above the slide plate is tolerated. Different types, round or rectangular designs, are available. The valves can be operated manually, pneumatically, or electrically.
Tube slide valves reduce or shut off the flow of material, depending on the position of the slide. The slide plate in this case is a tube section that closes in the direction of the conveying. Unlike the slide valve, this design has hardly any dead space. Optional equipment such as vibrators and spray nozzles are also available.
This is an integrated sensor which indicates the tension of the conveyor chain to ensure uniform chain tension.
Weight tensioning is used for high temperature products as well as for systems conveying abrasive products. It compensates for any kind of chain elongation and requires less maintenance than spring spindle tensioning.
The electromechanical chain tensioning device regulates the difference in chain elongation and shortening fully automatically. It is mainly used where long conveyors are operated under varying conditions or whenever small spaces inhibit the use of conventional weight tensioning.
Any kind of change in direction, depending on the conveyed medium, will cause increased friction, noise, and wear. In some cases, turn stations with rims or chain wheels provide a good solution.

The turn station type P with 45° redirection is designed for changing the direction in the return run of tall, vertical systems.
Adhesive products can easily be removed by means of scraping sprockets, cleaning discs, or brush cleaning systems.
Plungers are mounted to the tooth flanks of the drive sprocket, which push out adhesive or non-free flowing bulk materials stuck between the discs (forced discharge).
Oversized discs or brush discs, elastic seal discs or scraping discs clean the tubes of the conveying run and return run from the inside and prevent adherence.
Brush cleaning stations are used for forced discharge or cleaning. The plastic brushes are driven by small worm gear motors.
With this type of station, the bulk material can detach itself from the chain. Just before the chain enters the return run, two brushes clean off any possible residues.
This station has been especially designed for upright tube chain conveyors. Its operation is very similar to that of the brush drive station for vertical conveyors.
With this module, an inner brush kicks in as soon as the conveyor chain enters the discharge area (drive station). Therefore, the sprocket can operate free of any product already. Then, the outside brush clears the outside of the conveyor chain of any product residues.
Tube supports help to support the tube chain conveyor at regular intervals. For rough terrain, our height-adjustable hollow profile supports are the measure of all things.
Our versatile solutions are used to connect two tube chain conveyors or as a transition to a subsequent unit.
As the infeed element of every tube chain conveyor, we offer a wide variety of infeed variants, whether square, round for serving as a hopper or with an infeed aid.
We are happy to offer you a suitable control system for your conveyor system.The control unit is used to electronically control the tube chain conveyor and/or additional components.The most frequently used controls are PLCs.
