Tuoxing Launches TXZY-2.5 Aerial Work Platform Truck: The Robust, High-Performance Solution for Underground Mining and Tunnel Operations

1. Overview

Laizhou Tuoxing Electromechanical Equipment Co., Ltd. is proud to introduce the TXZY-2.5 Aerial Work Platform Truck — a purpose-built, heavy-duty elevated work vehicle engineered primarily for underground mining applications. The machine excels in aerial operations in environments that are otherwise inaccessible to conventional lifting equipment, including railway, highway, and hydraulic tunnels, as well as narrow, low-height, and muddy working faces.

The TXZY-2.5 represents the culmination of advanced international drivetrain technology and robust structural engineering, offering operators an unmatched combination of safety, power, and efficiency in the harshest underground conditions.

3. Powertrain — DEUTZ Air-Cooled Diesel Engine

The TXZY-2.5 is equipped with a DEUTZ (Germany) F6L914 air-cooled diesel engine featuring two-stage combustion technology and low-emission design — a world-class choice for underground operations where exhaust management is critical.

4. Advanced Drivetrain System — DANA (USA) Technology

4.1 Torque Converter

The TXZY-2.5 uses a DANA (USA) C272 single-stage, two-element torque converter with an integrated hydraulic pump drive unit. This provides smooth, stepless torque multiplication at low speeds — essential when navigating uneven underground terrain.

4.2 Powershift Transmission

The DANA R32000 powershift transmission allows gear changes without stopping the vehicle and without depressing the brake — a critical operational advantage in confined mine roadways. Operators can shift between 4 forward gears and reverse while the vehicle is in motion, maximising site productivity.

5. Comprehensive Hydraulic System

The TXZY-2.5 incorporates four independent hydraulic sub-systems, each designed and optimised for its specific function. Key hydraulic components are sourced from leading international suppliers.

5.1 Working Hydraulic System

• System rated working pressure: 14 MPa; safety valve set at 18 MPa

• Dual-function control: manual lever operation + wireless remote control

• Upper-body valve (electro-hydraulic proportional) controls: boom left/right swing, boom extension/retraction, platform levelling, platform rotation

• Lower-body valve (manual) controls: outrigger cylinder extension/retraction

5.2 Steering Hydraulic System

• Central articulated full hydraulic power steering

• Steering angle: ±40°; minimum inner turning radius ≤3,037 mm

• Shared triple pump with working system; dedicated steering directional valve

5.3 Braking Hydraulic System

• Rated system pressure: 15 MPa

• Components: brake pump, high-pressure filter, charge valve, solenoid directional valve, accumulator (×2), brake valve, check valve, hand oil pump

• Fail-safe: spring-engaged, hydraulically released — automatic braking on pressure loss

• Manual brake release system included for emergency towing

• Accumulator pre-charge pressure: 7 MPa

5.4 Torque Converter Oil Supply System

• Torque converter oil supply gear pump driven directly by diesel engine

• 10-micron precision filtration on supply line

• DANA-supplied hydraulic control components (except cooler, supplied by DEUTZ)

• Oil cooling circuit prevents premature oil ageing and bearing damage

6. Telescopic Boom Structure

The TXZY-2.5 features a precision-engineered articulating and telescoping boom arm assembly, providing exceptional reach and positioning flexibility for underground construction, maintenance, and inspection tasks.
