Feed system component kit

Doofor offers a set of supporting components for customers, which wish to build their own drill feed. Base machines for such drill feed would be excavators, mini-loaders and skid steer loaders.

The component kit includes an anodized aluminum profile designed, carriage plate for the rock drill, feed motor, feed chain and housings for the feed chain. The ground support module, valve block and its casing and hoses are also pre-designed for convenient drill system construction. Protective cover for the drill steel is also available.

The feed system component kit may be used as a back bone of a hydraulic drill system, and it should be installed and further constructed by a professional company. The component kits scope of delivery doesn’t include any kind of power unit, dust control system or safety features required that may be required by law and these features remain as a responsibility of the installing party.

Aluminum profile

Doofor offers an aluminum profile for rock drill feed constructors.

The profile material is aluminum alloy AlSi1Mg / AW-6005A-T6. The profile weights 10.6 kg / meter. It is recommended for rock drills with a mass of 100 kg or less. The aluminum profile stock length is 4.8 meters and other lengths are available on request. Feed beams are anodized to minimize corrosion.

 

Carriage plates

Universal carriage plates

Doofor supplies universal carriage plates for all Doofor rock drill models.

The universal carriage plate has the connections to attach a Doofor rock drill. A universal carriage plate has a flat lower surface for customization to match the requirements of the feed beam. Universal carriage plates can be equipped with a frame for a steel retainer. Universal carriage plates are often used when retrofitting a Doofor rock drill to an existing drill rig.
