Application: ZWZA and ZWZ3 series DC electromagnetic drum brakes are mainly used for electromagnetic cranes, various DC drives or DC power grid lifting, port loading and unloading, and deceleration and parking braking of various mechanisms in metallurgical machinery. It is not recommended to use various AC driven lifting, port loading and unloading, and metallurgical machinery
Compliance with standards:
The connection dimensions and braking torque parameters of ZWZA and ZWZ3 series brakes comply with JB/ZQ4386-86, and the technical requirements comply with JB/T7685-2006 standards.
. This series is mainly used to replace the old ZWZ series productsThe connection dimensions and braking torque parameters of the ZWZA series brake comply with the GB6334-86 standard. The technical requirements comply with the JB/T7685-2006 standard. This series is mainly used to replace the old ZWZ3 and ZWZ □ series products
Main features:
▲ Interlocking distance equalization device and tile automatic follow-up device, which can always maintain equal distance between the two tile blocks without adjustment, completely avoiding the phenomenon of one side brake pad floating against the brake wheel due to uneven distance.
The main swing hinge points are equipped with self-lubricating bearings, which have good transmission efficiency, long service life, and no need for lubrication during use▲ The brake spring is arranged inside the square tube and equipped with a ruler, allowing users to easily read the braking force torque value, eliminating the hassle of measurement and calculation
▲ The brake pad is a (with card slot) card mounted integral molding structure, which is easy and fast to replace. There are different materials of brake pads available for users to choose from, including semi metal (asbestos free) hard and semi hard, soft (asbestos free) brake pads.
▲ The new type of armature follower device can always maintain a good fit between the armature and the magnetic yoke
▲ Normally closed design, (power off) spring brake, (power on) electromagnetic release
