Drill Jumbo catalogue

HD220 Hydraulic DrifterFURUKAWA Hydraulic Jumbo series is equipped with the high-performance HD220 hydraulic drifter. A new dual damper mechanism attains the extremely high drilling performance and prolongs the service life of drilling tools such as bits and rods. Experience how smooth and speedy drilling can be.

The improved efficiency and power of the impact mechanism and the newly developed dual damper mechanism significantly increase the impact energy transfer efficiency. The drilling speed is improved by 15% over our previous model. Thanks to the dual damper mechanism, the HD220 requires less thrust for rock drilling. For use on everything from extremely hard rocks to fissured soft rocks, the HD220 can drill holes with a minimum hole deviation and maximum hole smoothness.

Optimized impact piston shapeAt Furukawa, we have conducted model analysis for energy transfer efficiency (rock breaking efficiency) on tens of thousands different piston shapes to find the shape that performs the best over a wide range of rock types, from extremely hard rocks to fissured soft rocks.

Dual damper (shock absorber)The dual damper is a shock absorber with a unique mechanism. It is equipped with a damping piston to absorb the reaction force and a pushing piston to give the proper thrust force to rods and bits (patent has been obtained in the USA and is pending in Japan, the EU, and other countries). The dual damper firmly holds the bits on the rock and transfers the shock wave from the impact piston to the tips of the bits to break the rocks. This makes it possible to drill with appropriate thrust, reducing unnecessary movement of the hydraulic drifter, the possibility of idle blows, and the deviation in the drilled hole. It also significantly increases the service life of bits and rods.

Compact valveThe use of small, lightweight valve for the impact piston significantly improves the response of the piston and the efficiency of the impact output.

The following functions are added to enable the breaker to be more durable even under the harsher operating conditions peculiar to tunneling:

1. The T-BOX type frame has been designed to especially realize sound suppression and vibration isolation, as well as extended durability.

2. Air compressor piping design prevents water/dust/earth/sand from entering the breaker main unit.

3. A water sprinkling nozzle is provided at the end of the frame, which helps prevent fine rock particles from scattering within the mining pit.

4. Auto grease piping automatically delivers lubrication to the front section, thus helping to further improve durability of the front section.

*Prepare an air compressor.
