TR300D Rotary Drilling Rig Drilling depth 95m,Drilling diameter 2500mm,Torque 310kN.m

New design with advanced technology, composed of advantages based on ORIGINAL Caterpillar undercarriage.

We can design and manufacture drilling rigs and piling machine according to customers requirements.

New design with advanced technology, composed of advantages based on ORIGINAL Caterpillar undercarriage.
They are the most versatile and used for deep foundation, such as construction of railway, highway, bridge and skyscraper.
The rotary drilling rigs can be specially equipped with telescopic friction & interlocking Kelly bar, and casing oscillator for suiting the following applications:
Cased bore piles with casing driven adapter through rotary head or optionally by casing oscillator powered by the base carrier itself;
Deep bored piles stabilized by drilling fluid or dry hole;
Soil Displacement Piling System

Mast triangle supporting structure reduced the turning radius and increased the stability of the whole machine during the operation.

Main features:
Maximum drilling diameter is 2500m, maximum drilling depth is 90m.
Adopt retractable CAT336D chassis.
The key components of hydraulic system and power system imported from Rexroth and Linder, or Brevini.
Innovative improvements and design ensures the structures of the whole machine simple, reliability and flexibility.
Advanced electronic control system match with Import electronic parts to bring a good interface of human and machine.
Applicable for different kinds of stratum, such as hard rock, frozen soil layer, clay layer, sandy gravel layer, strong and weak weathered rock, pebble layer, boulder layer, backfill layer etc.
