HRP / HRIG – Levelling caster series

with integrated truck lock, with top plate fitting or bolt hole female thread

The HRP and HRIG rigs are made from die-cast aluminum and have an integrated hard rubber truck lock and an adjustment wheel. The levelling caster can be attached to the application using a steel top plate fitting (HRP series) or a bolt hole female thread (HRIG series). The adjustment wheel integrated into the caster is used to make height adjustments.
The HRSP series is recommended if casters with a higher load capacity are required.
