Note:
- Purpose-Built for Tunnel Boring: This tunnel gantry crane is engineered specifically for tunnel excavation projects, with a compact 4.5m span and 25m ground gantry matched to tunnel portal dimensions.
- Anti-Wind Devices for Typhoon Weather: Equipped with dedicated anti-wind subassembly to secure the tunnel gantry crane during typhoon and severe weather conditions — critical for exposed outdoor tunnel sites.
- High-Torque Electromagnetic Disc Brake: The hoist is fitted with a high-torque electromagnetic disc brake for reliable load holding and emergency stopping, essential for underground material handling.
- Full VFD Stepless Speed Control: All motions on this tunnel gantry crane (hoisting 1.6-10 m/min, trolley 5-20 m/min, long travel 5-20 m/min) feature variable frequency drive regulation for smooth starting, precise positioning, and reduced mechanical wear.
- ED60% Hoist / ED40% Trolley Duty Cycle: The 9.5kW hoist motor at ED60% and 0.64kW trolley motor at ED40% are matched to the intermittent yet demanding duty cycle of tunnel excavation work.
- 2/1 Rope Reeving with φ11mm Wire Rope: The 2/1 reeving configuration doubles the lifting force and reduces rope stress, extending wire rope life in the dusty tunnel environment.
- Pendant + Wireless Remote Control: Dual control allows the operator to work from a safe position — critical when the tunnel gantry crane is operating near excavation faces.

Everything clients ask before using this tunnel gantry crane drawing — why the span is only 4.5m, how the anti-wind devices work in typhoon weather, why the hoist is ED60% and trolley ED40%, how the electromagnetic disc brake holds the load, 2/1 rope reeving, P22 rail, and what to send for a project tunnel gantry crane drawing and quote.
This tunnel gantry crane drawing package (No. MHO 5-4.5 A5) is delivered as a 2D + 3D Drawing Package PDF. It covers the full tunnel gantry crane: single girder, A-frame legs, end carriages, the 5t European wire rope hoist with high-torque electromagnetic disc brake, trolley traverse, SZW-100 + LDA long travel drives, full VFD electrical panel, anti-wind devices, and pendant + wireless remote control. The tunnel gantry crane drawing clearly marks S4.5m span, 4.5m total width, 25m ground gantry, 6m total height, 4.7m lifting height, and 13m travel length. It does not cover ground rails, rail foundation, or site power supply — those are site-side scope.
Yes — the 4.5m compact span is purpose-built for tunnel boring and underground excavation because:
A wider span (10m+) is not needed because tunnel handling is linear along the tunnel axis, not across a wide yard. The 4.5m span is matched precisely to the tunnel portal geometry.
The anti-wind devices on this tunnel gantry crane are a dedicated safety subassembly designed to secure the crane during typhoon and severe weather:
For sites with extreme wind loads (above 50 m/s), additional anchoring and wind-speed monitoring can be added — tell Yuantai your local wind zone at the enquiry stage.
ED stands for duty cycle (the percentage of time a motor runs within a 10-minute cycle). On this tunnel gantry crane:
The ED60% / ED40% split reflects the real working pattern of tunnel excavation: heavy hoisting, lighter trolley movement. This is more efficient than specifying both motors at the same ED.
The high-torque electromagnetic disc brake on this tunnel gantry crane is a critical safety component because:
In tunnel work, where the load may be suspended over workers or equipment, the electromagnetic disc brake is not optional — it is the primary safety mechanism.
2/1 rope reeving means the wire rope passes through a sheave system that creates a 2:1 mechanical advantage. On this tunnel gantry crane:
The 2/1 reeving is matched to the 5t capacity and 4.7m lift height — a standard configuration for tunnel hoists where reliability is critical.
Seven numbers on this tunnel gantry crane drawing must match your site, or the crane will not fit or operate correctly:
| Drawing Value | What It Must Match On Site | If It Does Not Match |
|---|---|---|
| Span: S4.5m | Tunnel portal width and rail center-to-center distance (4500 ± 6 mm) | Tunnel gantry crane girder and end carriages must be redesigned |
| Total width: 4.5m | Clear width available at the tunnel portal | Interference with portal walls or structures |
| Ground gantry: 25m | Available runway length at the tunnel site | Runway must be shortened or extended |
| Total height: 6.0m | Available clearance at the tunnel portal | Tunnel gantry crane structure must be re-profiled |
| Lifting height: 4.7m | Your required hook lift above rail level | Mast height or hoist reeving must be changed |
| Travel length: 13m | Your operating travel distance along the runway | Power feeding and buffer positions must be re-specified |
| Wind load / typhoon exposure | Local wind zone and typhoon frequency | Anti-wind device specifications must be upgraded |
If any of these seven differ from your site, tell Yuantai before ordering — each change affects price and lead time on the tunnel gantry crane.
To avoid surprises at installation, these items are outside the tunnel gantry crane supply scope unless you specifically add them:
Because the tunnel gantry crane operates in an exposed outdoor environment, the anti-wind anchoring foundation is a critical site-side item. Yuantai can provide anchoring load drawings as an optional item — just state this in your enquiry.
Send these eleven items and Yuantai will issue a free custom tunnel gantry crane CAD drawing, 3D model, and proposal within 24 hours:
The more complete the list, the faster and more accurate the tunnel gantry crane drawing, 3D model, and quote.
