45 رافعة قنطرية متحركة للحاويات مثبتة على السكك الحديدية

أ 45 ton rail mounted container gantry crane (آر إم جي) moves laden and empty 20 قدم / 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.

Container spreader

ال 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, التوأم 20 ft lifting is also available.

ميزات المنتج

45 رافعة قنطرية متحركة للحاويات مثبتة على السكك الحديدية

• 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 قدم — One spreader handles both ISO sizes with automatic twist-lock rotation and container presence detection; التوأم 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. مكافحة السيطرة على الطريق — 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.

الأسئلة الشائعة حول 45 رافعة قنطرية متحركة للحاويات مثبتة على السكك الحديدية

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

أ: 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?

أ: 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.

س 3: Which containers can the crane handle?

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

س 4: What power supply does the crane use?

أ: معيار 380 الخامس / 50 Hz via cable reel or conductor rail; other voltages and frequencies can be provided.

س 5: Can the crane be automated?

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

س6: What is the difference between an RMG and an RTG?

أ: 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.
