  • Pull-off force up to 2000 N up to 450 Pounds force (lb.)
  • Machine dimensions (LxWxH) 950 x 580 x 1400mm ~ 3 x 2 x 4.5 ft.

 

SAFETY FIRST

Who does not know it? Safety devices on machines often interfere with the ease of operation. Belt pullers in particular are often equipped with safety devices that make it difficult for the operator to thread the material. True to the motto “necessity is the mother of invention”, machine operators sometimes make do by dismantling or bridging safety devices. All of this leads to unacceptable safety risks.

This safety and ease of use were central elements during development. That is why our caterpillar puller was developed around the safety concept. Thus, the belt puller offers a new type of security concept that guarantees the highest level of security and does not restrict operation.

Safety features and protective equipment are not a nuisance but incorporated into functionality and ease of use.

The automatic pressure monitoring offers particular ease of use. After specifying the speed setpoint and pressing the “green button” (fig. 1), the puller starts automatically; further steps are not required by the operator.

A characteristic feature of the Gerlach caterpillar puller is the automatic pressure monitoring system. This automatic pressure monitoring assures that the product is not compressed in an uncontrolled manner, which can lead to permanent material damage and deformation of the product. As soon as the required friction between the upper and lower belt and the product has been achieved, the puller starts with a minimally required contact pressure that is continuously monitored.

In the standard version, extrudate heights of up to 60mm can be processed; alternative material dimensions can, of course, be realized according to customer requirements.

Permanent material stress, extrudate deformation and shrinkage due to high tensile forces are a well-known problem in quality assurance. The Gerlach puller BA 400 offers a special feature to counteract this problem. The machine is equipped with a “force control” function. With “force control” you can permanently measure the pull-off force and regulate the pull-off speed.

In continuous extrusion processes, ensuring material continuation and removal is an essential component in production lines.

Of course, the function of continuous material movement is integrated into many machines. However, it is not possible without a specialist who exclusively ensures this task! This refers to the caterpillar puller!

The requirements on the machine result from the production process, the product quality and the interaction between man and machine, as well as the demand to consider the highest safety standards.

The Gerlach belt puller sets new standards in the continuous pulling of profiles, hoses, pipes, or cables.
