YWZ2, YWZ4, YWZB, YWZD series electric hydraulic drum brakes are widely used for deceleration and parking (maintenance) braking of various mechanisms in lifting and transportation, port loading and unloading, metallurgical equipment, mining machinery, and engineering machinery.

Main Features

• The interlocking distance equalization device and automatic tile positioning device can always maintain equal distance between the tiles on both sides without adjustment, completely avoiding the phenomenon of one side of the brake pad floating against the brake wheel due to uneven distance.
• The brake pad is a card type integral molding structure, which is very convenient and fast to replace. It is available in different materials such as semi metal (asbestos free) hard and semi hard, soft (asbestos free), etc. for users to choose from.
• The main swing hinge points are equipped with self-lubricating bearings, which have high transmission efficiency and long service life.
• The brake spring is arranged inside the square tube and equipped with a ruler, making it very convenient for users to read the braking torque value, eliminating the trouble of measurement and calculation.
• The supporting series of thruster products have sensitive movements and long service life.

accessory

• Manual release device.
• Pad wear limit switch, which can display the signal when the brake pad wear reaches the limit (note: applied to brakes with automatic compensation devices)
• Release (open) the limit switch to display the signal indicating whether the brake is released normally.
• When using a thruster with a descent delay valve, it is possible to achieve delayed closure of the brake to meet the needs of certain specific situations.
