Production Process of 320t Overhead Crane for Casting Use

Brake - Crane Accessory

1. Application scope: Moving parts deceleration.

2. There are two types: friction brake and non-friction brake.

3. Crane brake is mainly constituted by brake pad, brake arm, brake wheel and brake releaser.

4. To reduce the braking torque and the size of brake frame, the brake is usually installed on the high-speed shaft. To meet the needs of high safety for large machinery, like mine hoist and elevator, the brake should be installed on the low-speed shaft which next to the working parts the large machinery.

Bearings used on Cranes

Bearings used on Cranes

1. There are two types: rolling bearing and sliding bearing. Rolling bearing has various standards and series, but its radial dimension, vibration and noise is bigger and its price is higher than the sliding bearing.

2. Rolling bearing is mainly constituted by outer ring, inner ring, rolling elements, bearing cage, seal and lubricant. Basing on the shape of rolling elements, rolling bearing is divided into two kinds: ball bearing and roller bearing.

Coupling on Crane

Pairs of Gear Coupling

1. Application scope:  Connecting different mechanism

2. It’s constituted by two parts. One connects the drive shaft, another connects the driven shaft.

3.  It’s the most used connecting components in shafting transmission of machinery.

4. There are two types: Fixed coupling and movable coupling.

5. In high-speed and heavy-load power transmission, some couplings could buffer and absorb shock to improve the dynamic performance of shafting.

Gantry Crane and Overhead Crane in Marble Processing Factory and Workshop

Weihua Crane Accessory - HOIST PULLEY

1. Application scope: Electric hoist

2. It’s simply constituted by some fixed pulleys and movable pulleys.

3. It’s widely used in cranes, winches and elevators.

Hoist Pulley

For light and medium duty overhead crane, its pulley could be cast by gray cast iron HT15-33 and ductile iron QT-10; for heavy duty overhead crane, the material could be cast steel ZG25 or ZG35; and for big-diameter (D＞800mm) pulley, it could be welded by carbon steel Q235-A.

Weihua Crane Accessory - Crane Hooks

1. Application scope: Electric hoist and winch

2. Two shapes: single hook and double hook. Single hook is easy to make and convenient to use, and its lifting capacity is usually under 80t. When the lifting weight is large, double hook is a better choose for its load-bearing is symmetric.

3.  It’s lifting capacity is 5t to 500t.

Crane Hooks

Hooks can be casting hook and laminated hook. Laminated hook is safer, and its dead weight is larger. It’s usually used to lift large weights and steel ladle.

Wheels of Overhead Crane and Gantry Crane

1. Application scope: Sustaining the crane running on the rails

2. Adopt ZG430-640 cast steel, and thermal treatment on surface.

3. Surface hardness is HB 300-350, and depth of quenching is more than 20mm.

Crane wheels are for sustaining the crane. Surface hardness is HB 300-350, and depth of quenching is more than 20mm.

Crane Wheels

Reducers used on overhead crane and gantry crane

1. Application scope: Electric hoist traveling.

2. Widely used in transmission equipment of mining, metallurgy, chemical industry, building material and light industry, etc.

3. The reducer should meet the mechanical strength needs when it’s used in cranes.

4. Crane reducer mainly used in mechanism of lifting, traveling, rotating and amplitude.

5. The needs of suspension-suit-type three-in-one reducer which is installed in traveling mechanism are small volume, light weight and compact structure; and its output end should be Internal spline which is directly installed in wheel shaft, input end should pass through a coupling and be connected with brake motor by flange; and its top should have holes for pin shaft and buffer device to fix on frame.

6. Crane motor and converter-speed-regulating motor for metallurgy are squirrel-cage rotor motor. Squirrel-cage rotor motor could meet the needs of different working conditions, such as frequent starting, braking, overload, reversing, over speed, collision and vibrating. And it also could meet the need of working under invert control, to realize soft start and four-quadrant operation.
