Haver & Boecker Canada launch Zip Guard to protect vibrating screen’s cross beams

Equipment manufacturer Haver & Boecker Canada (H&B) has developed a 1/2-inch-thick polyurethane liner to be installed on the cross beams of a vibrating screen to reduce the impact of passing material.

The Zip Guard is used to support equipment longevity and minimise downtime for maintenance. It is installed by a certified H&B technician and 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.


Haver & Boecker’s new polyurethane liner, Zip Guard, provides a protective barrier on vibrating screens’ cross beams, reducing wear and extending service life.

Cross beams, feed boxes, side plates, discharge lips, bar rails and shaft housing are structural components that provide rigidity in a vibrating screen, however, wear sacrifices the engineered rigidity and reduces the machine’s longevity. To combat this, H&B carries a full line of Tyrethane bar rail liners to protect the entire screen deck and increase the life of both the vibrating screen and the screen media.

Markus Kopper, Haver & Boecker Rocky Mountains general manager, said, “Alternative protective methods use rubber, which adheres directly onto the cross beam. The glue removal process is time-consuming, resulting in increased downtime for repairs. Zip Guard’s polyurethane barrier not only lasts longer and experiences less wear, but inspecting the cross beams for deterioration or cracking is 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 a customer notices wear, they can purchase a replacement and install Zip Guard to keep their machine up and running.”


Haver & Boecker engineers designed Zip Guard to support equipment longevity and minimize downtime for maintenance.


Customers can upgrade any new or existing Tyler vibrating screen with the protective liners.

A representative at H&B can also help determine the compatibility of the Zip Guard for non-Tyler vibrating screens. More information can be found on the website.
