Cable-Driven Monorail Transport Locomotive: How Yiqiao Coal Mine Cut Underground Labor by 67%
The cable-driven monorail transport locomotive is rapidly becoming the standard solution for underground cable and pipeline management in longwall coal mines. At the No. 5302 longwall face of Yiqiao Coal Mine, the introduction of a cable-driven monorail transport locomotive has fundamentally changed how crews manage power cables, water pipes, and high-pressure emulsion hoses — reducing a 2–3 person job to a single operator task.

What Is a Cable-Driven Monorail Transport Locomotive?
A cable-driven monorail transport locomotive is a purpose-built underground transport system designed for suspending and repositioning power cables, water pipes, and high-pressure emulsion hoses along longwall gate roads. Unlike conventional manual cable handling, the cable-driven monorail transport locomotive is hydraulically powered using the emulsion supply from the longwall face itself — no independent power unit is required.

Cables are installed once at the initial roadway setup. As the working face advances, all cable repositioning is handled mechanically via a hand lever — eliminating manual dragging entirely. According to the International Labour Organization’s mine safety guidelines, reducing manual handling in underground roadways is one of the most effective ways to lower musculoskeletal injury risk among underground workers.

Core Advantages of the Cable-Driven Monorail Transport Locomotive
1. 67% Labor Reduction
Tasks previously requiring 2–3 workers are now completed by a single operator. This directly reduces labor costs and frees personnel for higher-priority underground operations.

2. Eliminates Cable Slippage on Steep Gradients
On inclined roadways, manually repositioned cables frequently slide downhill during handling. The cable-driven monorail transport locomotive’s integrated self-locking device prevents uncontrolled movement, even on high-gradient slopes where manual control is unsafe.

3. Organized Roadway Layout
Power cables, water pipes, and high-pressure emulsion hoses are suspended in fixed overhead positions along the monorail track. This eliminates floor-level clutter, reduces trip hazards, and prevents vibration interference between high-pressure hoses and electrical cables — a common cause of cable damage in active longwall operations.

4. Single Installation, Continuous Use
Cables are laid once. All subsequent repositioning as the longwall face advances is handled by the cable-driven monorail transport locomotive — no re-routing, no re-laying, no additional installation labor per cycle.

5. Hydraulic Self-Lock Safety System
The self-locking mechanism activates automatically under brake failure conditions or when roadway gradient exceeds safe operating limits, providing a critical secondary safety layer in high-gas and steep-slope mine environments.

Application Scenarios
The cable-driven monorail transport locomotive is suited for the following underground environments:

Longwall coal mine gate roads with continuously advancing working faces
High-gradient roadways (slope >5°) where cable drag and slippage are operational safety risks
High-gas mine environments requiring explosion-proof, spark-free equipment
Narrow roadways where floor-level cable management creates obstruction and trip hazards
For mines requiring integrated personnel and material transport alongside cable management, Relystone’s full range of monorail transport locomotives — including diesel, lithium battery-powered, and pneumatic variants — can be configured as a complete underground haulage system alongside the cable-driven monorail transport locomotive.

Frequently Asked Questions
What is the power source for the cable-driven monorail transport locomotive?
The system uses emulsion hydraulic pressure supplied directly by the longwall face as its working medium. No independent power source is required at the unit level, simplifying installation and reducing equipment footprint underground.

Is the cable-driven monorail transport locomotive certified for high-gas coal mines?
Yes. All Relystone monorail transport locomotives comply with MA coal mine safety certification and explosion-proof standards, making them suitable for high-gas and dust-prone underground environments.

Can the system handle multiple cable types simultaneously?
Yes. The cable-driven monorail transport locomotive is designed to suspend and reposition power cables, water pipes, and high-pressure emulsion hoses simultaneously along a single monorail track installation.

What happens if the brake system fails on a steep gradient?
The integrated self-locking device activates automatically under brake failure conditions, preventing uncontrolled downhill movement on inclined roadways and ensuring operator safety.

How long does installation take?
Cable installation is a one-time process at initial roadway setup. Relystone provides full installation support, foundation drawings, and commissioning guidance as standard — with a typical equipment lead time of 15–30 days.
