HRLK – Levelling caster series
With foot pedal or adjustment screw
The HRLK levelling caster series is available in four different versions. The caster uses a pressed steel swivel rig with top plate fitting, a fixed operating lever and an integrated truck lock. The height of the truck lock is adjusted using the operating lever. The HRLK levelling caster with the suffix ...HN at the end of the product code has a top plate fitting and a swivelling rear operating and release lever which extends and releases the truck lock. Due to its mobility, the lever can also be pivoted under the edge of the trolley for improved safety. In contrast to the levelling casters in the HRLK and HRLK...HN series, the HRLK...F series adjusts the height of the wheel with the swivelling operating lever rather than the truck lock. The truck lock remains in place for stability and safety. The HRLK...VS height adjustment caster does not have a truck lock. An adjustment screw is used to make height adjustments while the unit is stable and fix the wheel in place.
