TR220 Rotary Drilling Rigs Max drilling depth 60-66m Whole machine
weight 65T
Designed and manufactured to ISO9001 standards and CE certificate.
Hydraulic piling rig 220 is composed of a Caterpillar base unit on
crawlers and of a drilling application module for:
a. Drilling with telescopic friction or interlocking Kelly
bars – standard supply
b. Optional casing oscillator application - optional
Main Features
1. Retractable original CAT 336D chassis with EFI turbocharged
engine ensures the stability of the whole machine meet the
performance on various applications and construction environment.
Advanced main pump adopted negative ow constant power variable
automatic control, which can realize the optimal matching in the
load and the output power of engine. Width of crawler can be
adjusted between 3000 and 4300mm.
Counterweight moved back wards increases the stability and
reliability
2. The system circuit is using Caterpillar hydraulic system as the
main control circuit and the pilot control circuit. With the
advanced loading back technology, the system achieves optimum
matching in negative flow constant power hydraulic pump and output
power of engine.Pilot control makes the operation exible,
comfortable, exact and safe. Various kinds of hydraulic elements
adopted world famous brand, such as Rexroth, Parker, etc. ensure
the hydraulic system high reliability.
3. Electric systems are from Pal-Fin auto-control, optimal design
of electric control system improves the control accuracy and the
feed back speed. Equipped advanced automatic switch of manual
control and auto control, the electronic leveling device can
monitor and adjust the mast automatically, and guarantee a
verticality condition during operation.
4. TR220D has separated auxiliary winch collocated on the mast from
triangle parts, good view and maintenance more convenient. The main
winch has highlights of touch-bottom protection, priority control
and fast line speed,which can greatly increase main winch releasing
speed and decrease ineective working time.
5. Compacted Parallelogram structure reduces the length and height
of the whole machine, thus reduce the machine's requirement on the
work space, easy transportation.
6. The newest designed winch drum structure is to avoid steel wire
rope tangling and lengthen the service life of steel wire rope.
