-feature

(1) Perfect oil leakage blocking

      The upper level 5 and lower level 2 seals are installed, and the seals are sensitive to various variables such as external dust and internal pressure of internal dust oil for each characteristic.

      It is configured to be able to seal.

(2) Efficient and reliable

      Even under severe conditions such as continuous operation or high-frequency use, it can be used with confidence.

      (Operation times: 600 times/hour)

      Protection level: IP65

(3) Meet various installation conditions

      The existing propeller can only be realized when the brake is installed horizontally, while the newly developed TB-HN brake has a completely sealed structure and

      Can operate normally.

(4) Lightweight

      The propeller material is made of aluminum die-casting, which is 54% lighter than the existing propeller. The thermal conductivity is 3 times higher than that of ordinary steel. The surface temperature is frequently kept below 60°C during use.

      The brake frame material is also made of high-quality castings (spheroidal graphite castings), with beautiful appearance, small and light structure.

(5) Structure

      The new single-column thruster mounted on the brake is divided into a cylinder part and a motor part. When the 4 bolts are removed, the motor and the cylinder

      It is separated for easy maintenance and simple maintenance, and is manufactured with a compact and sturdy structure to minimize the cause of defects.

      Because the lower part of the propeller is a prefabricated structure, it is easy to replace the TB Box of the propeller to the desired position and connect it to the crane's wiring.

      It can be easily rotated to fit.

(6) Fall time adjustment device

      The action time of the propeller can be adjusted from 0.3 to 6 seconds, which can be used for lifting motions that require sudden braking and main/traversal motions that require buffer braking.

      All available. An operating time of 6 seconds or longer can also be selected when ordering.

(7) No oil stains

      The internal structure of the propeller is made with a special coating, which eliminates the cause of internal pollution during the operation of the propeller and prolongs the service life of the product.

(8) Rotating friction parts do not need to be lubricated

    Since each dynamic friction part (connecting pin) of the brake is made of dry metal, there is no need to inject grease and it is easy to maintain

Any braking system has the following four basic components:

1) energy supply device, including various components that supply, adjust the energy required for braking and improve the state of energy transmission medium.

2) control device, including various parts that produce braking action and control braking effect.

3) transmission device, including the parts that transmit braking energy to the brake

4) brake, a component that produces a force (braking force) that impedes the movement or tendency of a vehicle, including a deceleration device in the auxiliary braking system.
