review

The BYWZ5 series explosion-proof electric hydraulic drum brake is widely used for deceleration and parking (maintenance) braking of various mechanisms in lifting and transportation, belt transportation, port loading and unloading, metallurgy, and construction machinery with explosion-proof requirements.

main features

• The brake pad is an explosion-proof pad with a card type integral molding structure, which is very convenient and fast to replace;
• Chain type equal clearance device, always maintain equal clearance between the two side tiles during use, to avoid the phenomenon of one side of the brake pad floating against the brake wheel due to uneven clearance;
• The main swing hinge points are equipped with self-lubricating bearings, which have high transmission efficiency, long service life, and do not require lubrication during use;
• The brake spring is arranged inside the square tube and equipped with a ruler to protect the spring from damage and contamination;
• Equipped with Ed series explosion-proof thrusters, it has sensitive action and long service life;
• Normally closed design, (power-off) spring brake, (powered on) thruster release.

Conditions of Use
