Product Description

TR400D rotary drilling rig is a newly designed self-erecting rig mounted on an original Caterpillar 345D base. It adopts advanced hydraulic loading back technology and integrates advanced electronic control technology, which makes the overall performance of the TR400D rotary drilling rig reach advanced world standards.

Applications

Drilling with telescopic friction or interlocking kelly bar-standard Supply
Drilling cased bore piles (casing driven by rotary head or optionally by casing oscillation)
CFA Piles by means of continuous auger
Either crowd winch system or hydraulic crowd cylinder system
Displacement piles
Soil-mixing

Key Performance & Design Features

Adopts Big-triangle support structure to guarantee the working stability for the drilling rig.

The main winch is driven by double motors, with double reducers and the single layer structure, which can prolong the useful life of steel wire rope and reduce working cost, at the same time ensuring the pull force and speed of the main winch.

Two movements with degree of freedom for the winch leading sheave device can be available, and adjust automatically to the optimal position suitable for steel wire rope, reduce friction and prolong the service life.

Adopts winch crowd system with the maximum 16m long stroke, and maximum crowd force and pull force can reach 44 Ton. Many methods of engineering can be applied well.

Use original CAT undercarriage and upper unit. Width of crawler can be adjusted between 3900 and 5500mm. Counterweight has been moved backwards and increased to improve the stability and reliability of the whole machine.

Key units of hydraulic system use Caterpillar hydraulic systems main control circuit and pilot operated control circuit, with advanced load feedback technology, which makes the flow distribute to every unit of the system according to need, in order to achieve operations that have the advantages of flexibility, safety, conformability, and exactness.

The hydraulic system is radiating independently.

The pump, motor, valve, oil tube, and pipe coupling are chosen from all first-class parts which ensure high stability. Every unit is designed to be high pressure-resistant (The max pressure can reach 35mpa) and can work in high-powered and full load conditions.

The electronic control system applies the DC24V direct current, and PLC monitors the working condition of every unit such as starting-up and extinguishing a fire of the engine, the upper rotation angle of the mast, safety alarm, the drilling depth, and failures.

The main parts of the electronic control system are high quality and adopt an advanced electronic leveling device which can switch freely between automatic state and manual state. This device monitors and controls the mast to keep it vertical during operation. The mast is automatically controlled and monitored by the advanced manual and auto switch electronic balance device to keep its verticality, which could guarantee the vertical requirements of the piling hole effectively and achieve the humanization layout of the control and friendly Human-machine Interaction.

The whole machine has a proper layout to reduce counterweight: the motor, hydraulic oil tank, fuel tank and the master valve are located at the back of the slewing unit, the motor and all kinds of valves are covered by a hood, offering an elegant appearance.

Frequently Asked Questions (FAQ)

What base undercarriage and engine does the TR400D use?

The TR400D rotary drilling rig is mounted on an original Caterpillar 345D base and utilizes a high-performance CAT engine with a rated power of 328 kW.

What are the primary applications of the TR400D drilling rig?

It is specially designed for drilling with telescopic friction or interlocking kelly bars, drilling cased bore piles, constructing CFA piles using continuous augers, displacement piles, and soil-mixing applications.

What is the maximum drilling depth and diameter of the TR400D?

The rig achieves a maximum drilling diameter of 2500 mm and can reach a maximum drilling depth of 95 to 110 meters depending on configuration.

How does the electronic leveling device support drilling accuracy?

It features an advanced manual and auto-switch electronic balance system that monitors and automatically adjusts the mast alignment to keep it perfectly vertical, ensuring highly precise pile holes.

What is the maximum working pressure of the hydraulic system?

The hydraulic system employs premium high-pressure components designed to withstand a maximum working pressure of up to 35 MPa, allowing the rig to work continuously under full load.

How does the main winch design reduce maintenance costs?

The main winch is driven by double motors and double reducers in a single-layer structure. This layout reduces friction, extends the operational service life of the steel wire rope, and ultimately lowers maintenance and running costs.
