Features of electric hoist double girder overhead crane

 

  1. Double girder structure makes the overhead crane bridge have sufficient strength, rigidity, and stability.
  2. Rail-in-middle box girder design of the double girder overhead crane thoroughly meets the requirement to strength, rigidity and stability.
  3. End beams of the double girder overhead crane is designed with simple structure which can be easily installed with main beam by high-strength bolts.
  4. CD or MD high quality wire rope electric hoist is used as lifting mechanism of the double girder overhead crane.
  5. Soft starting motors with light current is used on the double girder overhead crane. And also ground control can be used with the double girder overhead crane.
  6. Dual-motor independent drive device is adopted to reduce the wear of rail gnawing and reduce the possibility of wheel climb off track fault, etc.
  7. Motor of the double girder overhead crane is directly controlled by contactor, which can make the motor achieve single and double speed and reversing control.
  8. Frequency converter is used on the double girder overhead crane to change the frequency and voltage of motor power to realize the function of speed adjustment control of motor.
  9. Multiple safety protection system is adopted by the double girder overhead crane, including short circuit protection, no-voltage protection, emergency power off switch protection, overload limit protection, travel limit protection, zero and chain protection, ground protection, etc.

  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...
