Audited Supplier The D440 series drilling rigs are one of the most compact and lightweight closed cabin drilling rigs available. Small dimensions and a weight of 15,000 kg allow you to confidently work in limited areas with difficult terrain. The maneuverable tracked chassis ensures movement and operation on longitudinal slopes of up to 30° and transverse slopes of up to 10°. Despite its small size, the D440+ is seriously equipped: a 4" diameter hammer allows drilling wells with a diameter of 130 mm and a depth of up to 28 meters.
The spacious cabin of the D440+ model is the same as that of the "older" D460 and D480 models. All drilling operations are automated and do not require the driller to leave the cabin during operation. This makes this drilling rig ideal for Russian weather conditions. Convenient control joysticks, thoughtful ergonomics of the workplace and excellent visibility allow the operator to work for a long time and with minimal fatigue. The cabin is protected from external influences (FOPS).
The supply and replacement of drill rods from the drum mechanism occurs automatically (RHS); when equipped, the installation carries 7 rods, each 4 meters long. To protect drill rods from destruction, the D440+, like other models, is equipped with an anti-jamming system.
The hydraulic rotator transmits a torque of 2800 Nm to the drill string. The lifting force of 31 kN is sufficient to confidently lift the drill string even in fractured rocks or soft formations.
• Automatic drill rod extension system (RHS)
• Large capacity fuel tank of 350 liters
• Fully enclosed cabin with air conditioning and heater
• Independent air intake filter system for engine and air compressor
