YLZ25 Hydraulic Wheel Brake, Reliable Parking Holding Brake For Port Cranes

YLZ25 Hydraulic Wheel Brake, Reliable Parking Holding Brake for Port Cranes

YLZ25 Series Hydraulic Wheel Brake is a heavy‑duty spring‑applied hydraulic‑release safety holding brake specially designed for rail‑mounted port cranes. Under pressure‑loss condition, powerful springs push brake pads to clamp the crane wheel tread firmly for reliable parking and anti‑wind braking. When hydraulic oil pressure is supplied, hydraulic force overcomes spring force to retract the brake pads and release the wheel, allowing normal crane travelling.

This wheel brake provides dependable fail‑safe protection against strong wind, effectively avoiding crane drifting and run‑away accidents in open‑air port yards. Equipped with high wear‑resistant brake pads, it maintains stable clamping performance under long‑term cyclic operation. The robust cast‑steel main body adapts to heavy‑load and corrosive outdoor working conditions. Brake pads can be replaced without full disassembly, reducing equipment downtime.

YLZ25 Series Hydraulic Wheel Brake is a heavy‑duty spring‑applied hydraulic‑release holding brake, specially developed for large‑scale rail‑mounted port cranes. It follows the working principle of spring‑applied braking and hydraulic release. When the hydraulic system loses pressure, powerful compression springs push the brake pads to tightly clamp the tread of crane travelling wheels, generating stable braking torque to realize parking and anti‑wind holding function. When sufficient hydraulic pressure is supplied, hydraulic cylinder overcomes spring force to pull back the brake pads and release the wheels, so that the crane can complete normal travelling operation.

Adopting fail‑safe design, the brake automatically engages braking once hydraulic pressure fails, which greatly improves the safety of outdoor equipment. It can effectively prevent crane drifting and run‑away accidents caused by strong wind in open‑air port yards. Fitted with high‑performance wear‑resistant brake pads, the brake maintains stable friction coefficient and reliable clamping capacity under heavy‑load and frequent working cycles.

The main body adopts high‑strength cast‑steel structure, featuring outstanding impact resistance and corrosion resistance, adapting to harsh outdoor working environments such as ports and container terminals. The clearance between brake pads and wheel tread can be adjusted conveniently on‑site to meet assembly requirements of different wheel sizes. With modular structural layout, brake pads can be quickly replaced without disassembling the whole brake unit, shortening maintenance cycle and reducing operating costs. All transmission hinge points are precisely processed to ensure sensitive and stable action response.

As an essential safety protection component for port lifting machinery, YLZ25 series hydraulic wheel brake is widely equipped on gantry cranes, container cranes and other rail‑mounted large‑size lifting equipment for long‑term parking and storm‑proof anti‑creep protection.
