Flexible Clamshell Grab Bucket 360 Degree Rotating For Coal Loading

Flexible Design Clamshell Grab Bucket 360 Degree Rotating For Coal Loading

Description

Clamshell bucket includes rotary type and non-rotary type. Non-rotary type uses excavator bucket cylinder oil pathway, unnecessary to add hydraulic valve and pipeline, rotary type needs to add one set of hydraulic valve and pipeline to control. Cylinders are with piston protective device.

It also contains hydraulic type. Hydraulic clamshell bucket is designed to be attached onto an excavator .The dual hydraulic cylinders/ rams mounted on the outer rim of the bucket provides excellent digging force. The inner side of the bucket has a smooth surface for easy unloading of high viscosity material such as mud and clay, while the outer layer is reinforce with additional layer of wear strips. The bowl's radius has been optimized to match with the locus of the hydraulic cylinder/ram to deliver consistence full load for maximum productivity.

Hydraulic designs are meant for attaching to an excavator while the mechanical cable operated are designed to work with a broad range of canes. Ours grab are constructed with high tensile steel and wear resistant steel with capacity starting from 1 cubic meter and upward.

Characteristics and advantages

1. Clamshell bucket can be divided into 360-degree rotating type and non-rotary type.

2. Material is Q460 and NM360,

3. Driven by double cylinder synchronously

4. Bucket volume size is 0.2 to 5.0 CBM

5. Connecting part adopts direction activity joints, easy adjustment

6. Flexible design , easy installation, improve work efficiency

Performance

The clamshell most common and is used in silty, clayey and sandy materials. In mud the yaws in general have flat plates without teeth. In sand, clay and gravel, the yaws are fitted with in each other grabbing teeth, the two halves, shells, rotate around a hinge in the lower sheave block and re connected with the upper sheave block by rods. The closure/hoist cable is reefed several times between the head and the disc block to generate enough closing force. In mud the yaws are fitted with in each other grabbing teeth. For the removal of contaminated soil closed clamshells are used to avoid spillage.

For crane

Hand dumping clamshell single rope dual scoop grab is a kind of efficient tool for loading and unloading granular, small-block bulk cargo, such as coal, sand, mineral and bulk chemical fertilizer, which is suitable to the crane with single drum used on the working site such as port, yard. The characteristic of grab is simple structure, novel opening and closing mechanism, opening of grab is controlled by pulling the towing string at any place, light and convenient operation, exact and efficient action. The lifting capacity of crane is normally 5t-25t.

Application

For digging holes of construction ground work, chasm digging and mud, sand, coal, gravel loading . Especially for digging and loading in limited spaces like channel etc. Loading and unloading vessels, trains, cars.
