Safe use of crane brakes

 

  • After the brake is adjusted, the braking distance, braking torque and lifting load must be tested before the use of the brake, and the work can be done after the normal operation is confirmed.
  • After the brake is closed, the suspension object or car body should have a sliding distance within the unit time, that is, the inertia stroke.
  • The inertial travel is called braking distance when lifting rated load.
  • Operating mechanism: the braking distance is about 7% of the running speed (m/min).
  • Lifting mechanism: braking distance is about 1% of the lifting speed (m/min).
  • The brake must be able to reliably withstand 1.25 times the rated load.
  • Before each job, the object should be lifted away from the ground 100~200 mm, to observe whether the brake work is normal. After confirmation of the normal, you can start the operation.

Manual Chain Hoist Structure

图片
  CB type hand chain hoist When Manual chain hoists lifting weights upward, hands and pulled clockwise chains, bracelets wheel rotates counterclockwise when pulling hands to pull the chain down the stopper with separate brakes, ratchet pawl still under the effect of the five tooth long axis lifting sprocket drive runs in the opposite direction, so that the weight steady decline. Chain hoists generally use one-way ratchet friction disc brake, brake in the load on their own, with the ratchet pawl engages under the action of the spring, the brake safety. It is safe, reliable, easy maintenance, high mechanical efficiency, bracelets pull small, light weight and portability, smaller size and beautiful appearance, durable and suitable for factories, mines, construction sites, wharves, docks and warehouses for installation of equipment, lifting goods, especially for open and no power supply, but also shows its superiority. Selection of main parts chain hoists steel materials, the use...

Bridge Crane and Overhead Crane Systems

图片
  Bridge Crane = Overhead Crane = Overhead Bridge Crane This issue may be too elementary for many of you, please kindly note that Bridge Crane, Overhead Crane System and Overhead Bridge Crane are different titles for the exact same thing. This results in the customer meaning one thing while the design engineer is thinking of something entirely different.   The main travelling structure which spans the width of the bay is the Overhead Bridge Crane. The bridge consists of two end trucks and a bridge beam (bridging between the two end trucks).   End carriages/trucks: Located on either end of the bridge beam are the end trucks. They provide a connection point between the bridge beam and the house the wheels on which the entire crane travels. These wheels ride on the runway beam allowing access to the entire length of the building. Bridge Girders/Crane beams: The horizontal beam of the crane bridge supports the hoist. There can be either one or two bridge beams, but we’l...
