45 Ton Rail-Mounted Container Gantry Crane

A 45 ton rail mounted container gantry crane (RMG) moves laden and empty 20 ft / 40 ft containers inside rail container yards, dry ports and multimodal terminals. The crane travels on fixed rails laid along the yard, lifts containers with a telescopic spreader, and transfers them between rail wagons, truck lanes and stack areas. Fully electric and rail-bound, it delivers higher positioning accuracy and a smaller operating footprint than rubber-tyred cranes on the same layout.

45 Ton Rail-Mounted Container Gantry Crane

Container spreader

The 45 t capacity is sized for single-container handling of a fully loaded 40 ft container under the spreader — the most common load case in railway and inland container traffic. With a tandem-configured spreader, twin 20 ft lifting is also available.

Product Features

45 Ton Rail-Mounted Container Gantry Crane

• 1. Dual-unit dimensioning — Span and lifting height are quoted in metres or in container rows / stacking tiers, whichever the client’s engineering package uses. This eliminates conversion errors when the crane is matched to an existing yard drawing.
• 2. Telescopic spreader for 20 ft and 40 ft — One spreader handles both ISO sizes with automatic twist-lock rotation and container presence detection; twin 20 ft lifting on request.
• 3. Variable frequency drives — Hoist, trolley and gantry motions are VFD-controlled for smooth start/stop, accurate positioning and reduced shock to rail and structure.
• 4. Anti-sway control — Electronic sway damping shortens the positioning cycle in windy rail yards and improves drop accuracy on wagons and stacks.
• 5. Automation-ready design — PLC-based logic with a TOS/remote interface supports semi-automatic and future full-auto operation, plus remote monitoring for real-time diagnostics.
• 6. Complete safety package — Overload limiter, rail clamps and brakes, wind-speed alarm and interlocks, anti-collision between adjacent cranes, and full travel limit protection.
• 7. Low energy and maintenance cost — All-electric drive with regenerative options on lowering and braking; enclosed gearboxes and sealed bearings cut routine servicing.

45 Ton Rail-Mounted Container Gantry Crane Application

• ◆ Railway container yards and freight stations
• ◆ Dry ports and inland container depots
• ◆ Multimodal terminals (rail–road–port transfer)
• ◆ Border transshipment and cross-border rail stations
• ◆ Port back-up yards and bonded logistics zones

Typical duty: single 40 ft or twin 20 ft containers, 5-high stacking, up to 7 container rows plus truck lane, operating 24/7 in open-air yards.

FAQ About 45 Ton Rail-Mounted Container Gantry Crane

Q1: What does the span “6+1 rows” mean?

A: Six container rows under the gantry plus one truck lane. If your drawings show dimensions in metres, the same span is quoted in metric form — the two expressions are interchangeable.

Q2: What does lifting height “1-over-5” mean?

A: The crane stacks containers five high and can pick one more over a truck or wagon passing beneath. In metres, it is the distance from the rail top to the spreader at maximum height.

Q3: Which containers can the crane handle?

A: 20 ft and 40 ft ISO containers with the telescopic spreader; twin 20 ft lifting is available on request. The 45 t capacity covers a fully loaded 40 ft container.

Q4: What power supply does the crane use?

A: Standard 380 V / 50 Hz via cable reel or conductor rail; other voltages and frequencies can be provided.

Q5: Can the crane be automated?

A: Yes. The control system carries a remote interface for TOS and semi-automatic cycles; full automation can be added later without replacing main machinery.

Q6: What is the difference between an RMG and an RTG?

A: An RMG runs on fixed steel rails and is fully electric, giving precise positioning and lower cost per move; an RTG travels on tyres and is more flexible across the yard but less precise.
