YLZ Series Hydraulic Wheel Brakes For Large Cranes And Traveling Machinery

YLZ series hydraulic wheel brakes are normally‑closed, hydraulically released wheel brakes, mainly used for wheel‑side braking, anti‑wind, anti‑sliding and safety parking of port cranes, gantry cranes, shipyard cranes and other large outdoor traveling machinery.

Basic Information

Model: YLZ series

Type: Hydraulic wheel brake (wheel‑mounted brake)

Actuation: Hydraulic release, spring applied (normally closed)

Function: Travel braking, parking braking, windproof anti‑sliding

Working Principle

Brake state (power / hydraulic off):Built‑in heavy‑duty springs press the brake pads against the wheel tread, providing stable braking force.

Release state (hydraulic on):Hydraulic pressure drives the piston to retract the brake arms and open the brake pads.

Fail‑safe: Automatically locks the wheels when hydraulic pressure is lost, ensuring safety in storms or emergencies.
