LD-4 Machine

special drilling machine for marble and granite for holes 

Another kind of rock drill, called the drifter drill, is used for horizontal holes in mining operations and tunnel driving. It is mounted on some type of rig or frame and is mechanically fed into the work. Stoper drills are used primarily on up-hole or overhead drilling because of the automatic-feed characteristics. The usual stoper is a hammer drill with a self-rotating drill bit and an automatic feed by means of an air piston. Large air-operated earth drills, mounted on motor trucks on trailers, are utilized for digging water wells and blast holes for quarry operations.

The add-on vibrator is installed at the dipper stick boom of a hydraulic excavator and driven by its hydraulic system. Apart from characteristics like very short starting and stopping times, high revolutions, small noise level as well as low weight and high centrifugal forces, it is characterized by a low design height. This advantage appears particularly in buildings, under bridges, or power lines. Little usable length is lost due to its small design height. The add-on vibrator is used for piling and extracting sheet piles, trench sheet piles, steel beams and girders, pipes and casings, and full displacement sections.

The LD4 Drilling Machine is commonly used for quarry digging. It's a masterpiece that can drill vertically and horizontally up to 130 meters. The ball joint between the feed beam and the anchoring frame allows for 15 degrees of flexibility while digging in any direction. We produce and sell a wide variety of LD4 Machines to our clients. Our clientele from all over the world praises our LD4 machines.

Specifications:

• Lightweight, single-person operational, and easy to dock, dismantle, and transport.
• The required hole in horizontal mode is 50 mm, and it allows for 15 degrees of flexibility by using a ball joint between the feed beam and the anchoring frame.
• We also have machines for a variety of diameter sizes - 3.5", 4.5", and 7".
• In addition, we manufacture the LD4 slotter machine.

We make two distinct kinds of LD-4 machines.

• LD-4 with Grease Gearbox: The LD4 Drilling Machine, which works on grease, is simple to use and maintain. There is a gearing box and orbital grease system, and there is no need to replace oil on a regular basis. With grease, this can work for a long period. It has two-way hardened and ground handlers. For convenient operation, the control unit panel features a pressure regulator.
• LD-4 with Oil Gear Box: The fire-resistant hydraulic fluid technique is included in our LD-4 with oil gearbox to address valve erosion and thermal stability difficulties. It uses phosphate ester technology to slow down the spread of fire while protecting its components.
