DLZ25 Power‑Driven Wheel Brake, Reliable Parking Holding Brake For Port Cranes

DLZ25 Power‑Driven Wheel Brake, Reliable Parking Holding Brake for Port Cranes

DLZ25 Series Power‑Driven Wheel Brake is a heavy‑duty spring‑applied electric‑release safety holding brake for rail‑mounted port cranes. Under power‑off condition, powerful compression springs push brake pads to firmly clamp the crane wheel tread for stable parking and anti‑wind braking. When powered on, the electric driving unit overcomes spring force to retract brake pads and release wheels, enabling normal crane travelling.

Adopting fail‑safe safety concept, the brake engages braking automatically once power supply is cut off, effectively avoiding crane drifting and run‑away accidents in open‑air port yards. Equipped with high wear‑resistant brake pads, it maintains consistent clamping performance under long‑term frequent operation. The rugged cast‑steel main body adapts to heavy‑load and corrosive outdoor working conditions. Brake pads can be replaced without full unit disassembly, minimizing equipment downtime.

DLZ25 Series Power‑Driven Wheel Brake is a heavy‑duty spring‑applied electric‑release holding brake specially designed for large rail‑mounted port cranes. It follows the working principle of spring‑applied braking and electric release. When power supply is cut off, high‑power compression springs push the brake pads to tightly clamp the tread of crane travelling wheels, generating stable braking torque to achieve parking and anti‑wind holding function. When energized, the electric actuator overcomes spring force to pull back the brake pads and release the wheels, so that the crane can perform normal travelling movements.

Benefiting from fail‑safe design, the brake automatically applies braking once power fails, greatly enhancing safety for outdoor field equipment. It effectively prevents crane drifting and run‑away accidents caused by strong wind in open‑air port and container yards. Equipped with high‑performance wear‑resistant brake pads, the brake maintains stable friction coefficient and reliable clamping capacity under heavy‑load and frequent cyclic working conditions.

The main body adopts high‑strength cast‑steel structure with outstanding impact resistance and environmental adaptability, suitable for harsh outdoor working scenarios such as ports and container terminals. The clearance between brake pads and wheel tread can be conveniently adjusted on‑site to match different wheel assembly requirements. Thanks to modular layout, brake pads can be quickly replaced without complete disassembly of the brake unit, shortening maintenance cycles and reducing operating costs. All hinge transmission parts are precisely machined to guarantee sensitive and stable action response.

As an essential safety protection component for port lifting machinery, DLZ25 series power‑driven wheel brake is widely installed on gantry cranes, container cranes and other large‑size rail‑mounted lifting equipment for long‑term parking and storm‑proof anti‑creep protection.
