Crane fitting, coiling block

The material is ductile iron or steel

Used by mining fittings

We can produce parts based on clients' samples or drawings and arrange special engineers to inspect the quality of products

Reel material generally can be used when using iron need special steel or use steel plate welding manufacturing

Product Instruction

The drum is the part used to wind the wire rope in the hoisting mechanism. Reel and reel shaft, flanged ring gear, Roller hub, bearing and bearing seat etc. make up the drum group. When one end of the reel shaft is equipped with a rotary lift limit position limiter When the switch of the brake is turned on, it must be ensured that the reel shaft rotates synchronously with the rotating shaft of the upward limit switch. Scroll material – general made of cast iron. If necessary, it can be made of cast steel or rolled and welded with steel plates.

Technical Features

The drum is an important part of the drum group and requires regular safety inspections to prevent problems with components and cause the entire equipment to fail.

Due to the accident that the wire rope has cracks in the drum group, the cracked drum group should be scrapped and cannot be used.

When the wear depth exceeds the allowable center of gravity, the wall thickness of the drum shall not be less than 80% of the original wall thickness.

There should be no cracks on the wheel bolts, and other connecting screws should be tightened.

Cast Iron Type Grooved Crane Rope Drum

Crane drum is the component to wind wire rope in the lifting mechanism.

We are a professional crane manufacturer. Accessories as an important part of the crane, we mainly have hooks, wheels, grabs and so on. Can quickly choose the right spare parts for your equipment.

Feature:

The material of this kind of crane drum is cast iron HT200.

Cast iron type crane drum is more prevalent than the other two as follows.

Centrifugal casting is used in the process of production.

The wire rope can be better protected owing to the material of cast iron.

Steel Plate Type Grooved Crane Rope Drum

Crane drum is the component to wind wire rope in the lifting mechanism.

We are a professional crane manufacturer. Accessories as an important part of the crane, we mainly have hooks, wheels, grabs and so on. Can quickly choose the right spare parts for your equipment.

Feature:

The material of this kind of crane drum is steel plate, Q235, Q345.

It is more common than cast steel type crane drum.

Welding is used in the production process of steel platetype crane drum.

It is easy and convenient to produce.
