Prevent excess wear on the track and trolley—only the wheels of these push trolleys come in contact with the beam. Trolleys can be installed anywhere along the beam.

Open and close almost any hand-wheel operated overhead valve from the floor. These wheels can also be used to operate hatches, skylights, and other overhead components. Use these wheels with galvanized steel lock-link chain (not included).

Made of high-strength ductile iron, these wheels withstand impact better than other wheels to open and close large or stubborn overhead valves from the floor. They can also be used to operate hatches, skylights, and other overhead components. Use these wheels with galvanized steel lock-link chain (not included).

Push to move material along the conveyor.

Height is measured from the bottom of the track to the center of the connection holes.

Tensioners take up slack and allow you to adjust tension on your roller chain or belt. Position the adjustment arm to control tension in a 360° arc. They are for use with idler sprockets or pulleys.

Designed for large belt and chain drives, these tensioners maintain correct drive tension for smooth operation, maximum power, and a long service life. They're spring loaded, which keeps constant tension on a belt or chain and automatically adjusts for changes in loads. An idler shaft (sold separately) is required.
