Key Features & Structural Design
1Chassis & Layout Optimization

The newly designed and developed multifunctional upper chassis is widened, featuring a built-in hoist and laterally arranged hydraulic main valve. The structure is compact and stable, facilitating convenient maintenance. The cab is moved forward and equipped with a top protective cover, keeping the working surface close. It is arranged horizontally for easy disassembly.

2Telescopic Chassis & Slewing Bearing

The self-made telescopic chassis features a compact structure and convenient telescopic disassembly. A high-quality German Rothe Erde slewing bearing is selected to ensure a long service life.

Slurry Purification & Environmental Performance
01. Control Slurry Index By fully purifying slurry, it is favorable to control the slurry index, reduce drill sticking phenomena, and improve drilling quality.
02. Enhance Efficiency By thoroughly separating the slag and soil, it is highly favorable to enhance overall drilling efficiency.
03. Cost Reduction By realizing the repeated use of slurry, it saves slurry-making materials and thus reduces construction costs.
04. Eco-Friendly System By adopting close-cycle purification and achieving low water content in removed slag, it effectively reduces environmental pollution.
3PLC Controller & Correction System

Equipped with an advanced programmable PLC controller, inclinometer, and correction system to ensure precise groove quality. A high-resolution touch screen with large memory is utilized for real-time monitoring, display, recording, and printing of the excavation process.

4Cummins EFI Turbocharged Engine

The imported Cummins QSM 11 EFI turbocharged engine is easy to maintain. It matches the hydraulic system, negative feedback control main pump, and engine power output dynamically to adapt to various working conditions, ensuring high efficiency, long life, and excellent fuel economy.

5German Reducer & Rexroth Motor

Equipped with a built-in German imported reducer and brake, Rexroth motor, single-row rope, and double winch with a large-diameter drum to significantly boost the winch's work efficiency and durability.

6Reinforced Mast Mechanism

The new mast lifting mechanism makes raising and lowering the mast much more convenient. The joints of the masts feature a reinforced structural design to resist strong impacts.

7Multifunctional Bucket Body

Features an adjustable weight bucket body equipped with grab bodies and bucket heads of different weights to match varying strata requirements. An optional bucket body slewing device and impact grab are available. Additionally, a 200-ton large thrust cylinder allows deeper trenching in complex geological formations.

Frequently Asked Questions
What diesel engine is used in the TG60 model?

The TG60 utilizes an imported Cummins QSM 11 EFI turbocharged engine, designed for high efficiency, excellent fuel economy, and ease of maintenance under varying working conditions.

What is the maximum groove depth and width range?

The maximum groove depth is 70 meters, and the groove thickness of the grab bucket (open width) ranges from 0.6 to 1.5 * 2.8 meters.

How does the slurry purification system lower construction costs?

It separates slag and soil thoroughly, allowing the slurry to be repeatedly reused. This reuse reduces the consumption of slurry-making materials, significantly lowering construction costs.

What control system ensures the excavation quality?

The machine adopts an advanced programmable PLC controller, inclinometer, and correction system. It features a high-resolution touch screen for real-time monitoring, recording, and printing of the excavation process.

How does the winch system improve operational efficiency?

The system is equipped with a German imported reducer, German brakes, a Rexroth motor, a single-row rope, and a double winch with a large-diameter drum to greatly improve the service life and work speed of the winch.

Can the grab bucket handle complex geological formations?

Yes, the multifunctional bucket features adjustable weights, customizable grab bodies, and optional slewing/impact devices. Supported by a 200-ton large thrust cylinder, it is capable of trenching deeper in highly complex formations.
