The Rail & Metro Challenge

Why Standard Lift Equipment
Often Falls Short in Rail Environments

Rail maintenance demands more than height. Passage envelope, power source, rail mobility, documentation and task position all need to be checked before a machine can be approved for the site.

🚇
Tunnel Dimensions Are Non-Negotiable
Metro tunnel cross-sections are structurally fixed. A machine that is too wide cannot physically enter the envelope or still leave working space beside rolling stock. The MX MINI keeps a 0.76m overall width for the narrowest routes, while the CLP10TG and MC400TG are engineered to a 1.2m stowed width for broader tunnel access tasks.
→ Solution: MX MINI 0.76m · CLP10TG & MC400TG 1.2m tunnel-access platforms
🛤️
On-Track and Off-Track Mobility
Rail maintenance often requires both track travel and ground access across ballast, trackbed, and paved depot floors. Switching between modes can cost time and require extra equipment positioning. The CLP10TG and MC400TG support steel-wheel travel on rails and crawler travel off-track.
→ Solution: Dual steel-wheel + crawler mode on CLP10TG & MC400TG
All-Electric for Enclosed Environments
Tunnel and enclosed station environments often restrict diesel exhaust during maintenance windows. The CLP10TG runs on a 48V/240Ah all-electric system for zero-exhaust overhead work. MX MINI uses 2×12V/114Ah battery power for compact indoor tunnel and depot tasks. The MC400TG uses electric primary power with a 3.6kW diesel only as an emergency backup.
→ Solution: CLP10TG full electric · MX MINI battery powered · MC400TG electric + emergency diesel
🏗️
Complex Access Requires Articulating Reach
Tunnel structures, overhead catenary systems, and bridge elements require the ability to work up and over obstacles. The HA12JRTG’s rail-guided articulating boom provides 6.5m horizontal reach and 6.56m up-and-over clearance, with 360° turntable rotation for full coverage from a fixed rail position.
→ Solution: HA12JRTG — 6.5m outreach · 6.56m up & over · 360° rotation
🚧
Emergency Rescue & Hoisting Demands
Railway maintenance includes emergency rescue scenarios and equipment hoisting in confined track corridors. Standard transport vehicles lack integrated lifting capability for on-track use. The MC400TG integrates a 3t-capacity crane with a 4m horizontal range directly on a rail-capable tracked chassis.
→ Solution: MC400TG — 3t crane · 4m reach · Manual + remote control operation
📐
Train-Side Tasks Need Lateral Standing Room
Door system checks, carriage body servicing, cable inspection and tunnel-side fitting work often need the operator to stand offset from the platform centreline. The metro version of the MX MINI adds a laterally expandable top platform so operators can work beside the train side while keeping the base machine compact.
→ Solution: MX MINI metro variant — lateral top platform · 0.76m chassis · battery powered

PROJECT NOTE

For tunnel overhead work, buyers usually check three items before model selection: stowed width and height against the access route, electric operation for enclosed sections, and whether the machine can move between crawler and steel-wheel mode without extra transfer equipment. CLP10TG and MC400TG are configured around these checks.

Tunnel Access ReviewWidth · height · electric operation · on/off-track movement
PROJECT NOTE

For rail-guided boom access, the key confirmation points are track gauge, work envelope, overhead reach, platform load and documentation package. HA12JRTG is normally reviewed against project drawings so the rail wheel set, boom reach and safety systems match the route and maintenance task.

FAQ

Rail Access Questions

Common questions from rail operators and infrastructure contractors about TG Series and MX MINI configurations. Our team responds within 24 hours.

Ask Our Team →
What rail gauge does the HA12JRTG support?

The standard HA12JRTG specification uses a 1.5m rail gauge with customised rail wheel sets. The wheel sets are driven by the vehicle’s original Yanmar diesel power system. Custom gauge configurations for 1,435mm standard gauge, 1,067mm, and 1,000mm metre-gauge tracks are available as OEM options — contact us with your track specification.

Can the CLP10TG be used on restricted tunnel access routes?

The CLP10TG has a stowed width of 1.2m and stowed height of 2.2m, which is designed for restricted tunnel access routes. Final passage should always be checked against the project’s door, curve, ramp and clearance drawings. The flip-up front and rear axles reduce the machine footprint for access and also provide the 25% gradeability needed for ramps and sloped access routes.

What makes the MX MINI metro variant different from the standard MX MINI?

The metro version is based on the MX300S, MX390S, and MX450S narrow electric scissor lifts but adds a laterally expandable top platform for operator standing space beside the train body. It is intended for tunnel and depot maintenance where side access is more important than rail travel, while keeping the compact 0.76m chassis and battery-powered indoor operation of the base MX MINI range.

How does the MC400TG switch between crawler and steel-wheel mode?

The MC400TG’s dual-mode system allows switching between crawler travel for off-track surfaces and steel-wheel rail travel for on-track operation. This transition reduces equipment transfer time between worksite access and on-track positioning. Specific switching procedure details are covered in the operator documentation supplied with each unit.

What is the MC400TG emergency diesel backup for?

The 3.6kW RD178 diesel engine is an emergency power system only — it is not the primary drive. Primary operation is electric via the 48V/240Ah battery system. The diesel backup helps the machine move or operate the crane if the battery system is depleted or fails during a remote or tunnel worksite, reducing the risk of the machine being stranded on track.

Can these rail platforms be supplied with inspection lighting equipment?

Yes. TG Series models and MX MINI metro variants can be configured to carry construction lighting and inspection equipment. Custom mounting brackets, cable management, and power integration can be matched to the lighting or inspection tools specified for your project.

Is third-party inspection (SGS, Bureau Veritas, TÜV) supported?

Yes. Pre-shipment inspection by SGS, Bureau Veritas, TÜV Rheinland, and other internationally recognised bodies is supported for the rail access portfolio. Arrange at order placement so inspection scheduling and factory access can be confirmed before production and shipment.
