In addition to the HRP series with an integrated truck lock and adjustment screw, Blickle’s standard range includes the HRSP heavy duty design. The HRSP bracket of the HRSP series is made of die-cast aluminium with an integrated aluminium truck lock. The height can be adjusted using a spanner. The product is fitted using the steel top plate fitting. The levelling castors in this series are frequently used for applications which require a relatively low level of mobility, e.g. trade fair construction.
