Safe use of overhead crane brakes

 The reliability of the brake is critical. First, the structure and performance of the brake must be mastered. The fault and its causes must be very clear. It needs to regular inspection and maintenance.

Common faults and causes

a.Insufficient braking torque:

  • Brake belt or brake wheel worn seriously or partially damaged;
  • There is oil stain or loose main spring between brake belt and brake wheel;
  • Some parts are stuck, worn, loose and so on, such as movable hinge clamping, locking nut loose, resulting in adjustment lever loose;
  • The drive system of the slack brake is inflexible.

b.The brakes suddenly failed:

  • Severe wear or damage of brake belt;
  • The long stroke electromagnet is stuck or the rod is dropped between the armature and the horizontal lever.
  • Brake main parts damaged or main spring failure;
  • Hydraulic push rod or hydraulic electromagnetic push rod do not move;
  • Electrical failure and so on.

  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.

  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...
