Haver & Boecker introduce Zip Guard for screen wear protection

Zip Guard

New polyurethane liner designed to reduce impact of passing material in Tyler vibrating screens

HAVER & Boecker have expanded their product portfolio with the addition of Zip Guard – a half-inch thick polyurethane liner for installation on the cross-beams of Tyler vibrating screens to reduce the impact of passing material.

‘Cross-beams take the brunt of the impact in vibrating screens and most machines do not come as standard with protective liners, which means they experience wear from day one,’ said Markus Kopper, general manager of Haver & Boecker Rocky Mountains.


Installed by certified Haver & Boecker technicians, Zip Guard is available for all Tyler vibrating screens and offers easy access to the beam as it uses industrial-strength ties to attach the liner to the beam.

Alternative protective methods include rubber, which adheres directly on to the cross-beams. However, the glue removal process can be a time-consuming process, resulting in increased downtime for repairs.

According to Haver & Boecker, Zip Guard’s polyurethane barrier not only lasts longer and provides less wear, but inspecting the cross-beams for deterioration or cracking is much simpler than the glue alternative, as the liners are simply installed using industrial-strength ties.

Cross-beams and liners should be inspected regularly and when customers notice wear, they can purchase a replacement and install Zip Guard to keep their machines up and running.

‘In this industry, operations don’t have time for lengthy maintenance downtime,’ said Mr Kopper. ‘This dilemma led us to develop Zip Guard, to ensure customers’ machines can take the impact and run efficiently for longer intervals with minimal wear.’

Cross-beams, side plates, feed boxes, discharge lips, bar rails and shaft housings are all structural components that provide rigidity in a vibrating screen. Over time, regular wear reduces the engineered rigidity required for the longevity of the machine.

To combat wear, Haver & Boecker carry a full line of Tyrethane bar rail liners to protect the entire screen deck and maximize the life of both the vibrating screen and screen media. Customers can upgrade any new or existing Tyler vibrating screen with these protective liners.
