10T-100T Heavy Duty Industrial Double Girder High Speed Overhead Crane

The main components of the double girder high speed overhead crane:

1. Hook group: It is a take-up device. Note: there must be no cracks on the surface of the hook;

Wear and breakage of the pulley rim.

2, pulley block: divided into moving pulley group and fixed pulley group. Note: Is there a crack on the surface; work.

Whether the pulley is flexible or not, and whether the pulley rim is broken. After the pulley is broken, the user often uses

Brazing (brass water soldering) or electric welding repair for continued use. Due to uneven heating,

The pulley is deformed and the hardness is not uniform, which will cause the wire rope to wear abnormally and the welding quality is not good. Easy to guarantee, so welding is not allowed.

3, wire rope: Note: broken wire, broken strands, knotted, rust, pitting. Apply a lithium grease to the roll to lubricate.

4. Reel set: It is the part used to wrap the wire rope in the hoisting mechanism. Gear coupling

The reel group is a closed transmission with good grouping.

5, reducer: is to reduce the high speed of the motor to the work required by various agencies

Rotating speed. Commonly used horizontal reducer ZQ, vertical reducer ZSC. Note: check the oil level; slow down

The device runs smoothly, there should be no beating, impact and severe or intermittent noise, the sound is even;

The fastening and joints must not be loose.

6. Coupling: used to connect two coaxial lines or substantially parallel shafts to transmit torque

At the same time compensate for a small angle and radial offset. Commonly used CL gear couplings, CLZ teeth

Wheel coupling, brake wheel gear coupling. Note: lubrication, tooth wear.

7. Brake: It is usually mounted on the high speed shaft of the mechanism to reduce the braking torque. Electric hydraulic

The block brake model is YWZ. Note: Lubricate the rotating shaft pin; observe whether the brake pad is burnt or has a burnt smell; whether the friction surface of the brake wheel is oily.

8. Wheel set: The wheel and the angular bearing box are assembled together to form a wheel set. Wheel by rim

Points: double rim wheel, single rim wheel; note: wear of the rim. The rim is less than 10 millimeters

Time should be reported in time and closely observed.

9. Buffer: used to absorb crane (or trolley) and block (or meet) or the same span

The energy produced by the collision of adjacent cranes. Divided into: rubber bumper and spring type

buffer. Note: Check that it is intact.

10. Resistor: An appliance used to limit the motor current. The mechanism starts smoothly and reduces shocks.

11. Conductive device: power conductive device and trolley conductive device. Safety slip line collectors cable pulley

12, travel switch: according to the use can be divided into the end switch (limit switch) and safety switch (guarantee

Protection switch). The end switch is used to limit the operating range of the working mechanism and is installed at the end of the stroke. Commonly used models: LX10-11, LX7-1; Safety switch is used to protect personal safety, often

Model: LX19A-111.
