Overhead Crane Industrial brake
Core performance highlights

YWZ4 is a power-hydraulic drum brake specially designed for heavy loads. It operates based on the principle of spring braking and hydraulic release, mainly providing strong "braking" for the lifting mechanism of cranes to prevent heavy objects from accidentally sliding down.
- Super strong braking force: The braking torque ranges from 40 to 12500 N·m, and it can grip brake wheels with a diameter of 800mm. It is applicable to various heavy lifting scenarios.
- Power-off stop: With a normally-closed design, it will automatically lock the brakes upon power loss or failure, preventing the hook from sliding, ensuring extremely high safety.
- Later maintenance is hassle-free: The key moving parts are equipped with self-lubricating bearings, so no lubrication is required during daily use. The brake pads are of the snap-in type, and if damaged, they can be replaced directly, which can be done in just a few minutes, making maintenance convenient and fast.
Standards Compliant
The dimensions and braking torque parameters of Overhead Crane Industrial brake series brakes comply with JB/ZQ4388-2006 standard, technology requirements comply with JB/T6406-2006 standard.
Main Feature
- Safe and reliable performance, smooth braking, high action frequency.
- Main hinge points are equipped with self-lubricating bearing, making high efficiency of transmission, long ser vice life.Lubricating is unnecessary during operation.
- Interlocking shoe clearance balancing device and shoe auto-aligning device constantly equalize the clearance of brake shoes on both sides and make adjustment unnecessary,completely avoiding brake lining one side sticking to brake wheel.
- The non asbestos brake pad and the brake pad adopt the clamping plug-in type. It is safe and reliable, convenient and quick to replace.
Operating Condition
- Ambient temperature:-20℃~+40℃
- Flammable, explosive and corrosive gases are not allowed in the surrounding working environment,otherwise anti-corrosion products should be used.
- Relative humidity:the relative humidity of the air is not more than 90%
- The altitude of the place of use shall not exceed 2000m
- Operating duty:intermittent (S3-60%) and continuous(S1).
- Voltages: three-phase AC, rated voltage is 380V~460V,frequency is 50Hz/60Hz.
- Special requirements can be discussed before production.

Daily maintenance of YWZ4 brake
Brake pad and brake drum alignment: Ensure that the contact area between the brake pad and the brake drum is ≥ 70% to 80%, and there is no uneven wear.
Friction plate thickness: Measured visually or by measurement. If the wear reaches the minimum allowable thickness specified on the nameplate, it should be replaced immediately.
Oil level of the propeller: The oil level of the Ed series electric hydraulic propeller should be no lower than the lower limit of the viewing window. If the oil is insufficient, add hydraulic oil in time.
Propeller operation: When powered on, it should be opened immediately; when power is cut off, the brake should engage smoothly without any jamming, with no abnormal noise or violent vibration.
Brake wheel surface: No oil stains, water marks, deep grooves or cracks. If there are oil stains, they must be thoroughly removed to prevent slipping.
Each locking nut: Ensure that the anti-loosening components such as the brake torque adjustment nut and the retraction distance adjusting bolt are not loose.
