Fixed Column Cantilever Crane (Counterweight Type): the "mobile heavy load station" of the railway yard, a lifting fortress that can be lifted and moved at any time
Next to the tracks in a railway maintenance workshop, locomotive wheels (weighing 8 tons) quietly await lifting. In the freight yard, 20-ton containers are piled up at the edge of the tracks, but crawler cranes are unable to reach them due to scheduling delays. Like a "mobile heavy-load lighthouse," a fixed-column cantilever crane (counterweight type) uses a "counterweight base as an anchor and a cantilever as an arm" to quickly "set up camp" along the railway line, solving the "flexibility and heavy-load" contradiction in outdoor railway lifting.
Technical Parameters:
| Lifting Capacity | 10~30 tons (single beam 10-16 tons, double beam 20-30 tons) |
| Cantilever Span (swing radius) | 6~15 meters (double beam span ≤12 meters, single beam ≤15 meters) |
| Rotation Angle | 360° full rotation (standard) |
| Lifting Height | 6~12 meters (double winch travel, adapted to railway vehicle height) |
| Counterweight Configuration | Built-in ballast (iron sand + concrete, 30-80 tons) |
Dominant Applications: The "Lifting Capillaries" of the Railway System
1. Railway Maintenance: An Aid to Locomotive "Heart Surgery"
The 360° rotating cover covers the maintenance platform, lifting a 5-ton motor into position with ±5mm accuracy. Combined with laser navigation, it requires 50% less space than an overhead crane, eliminating the need for workers to tear down walls or move vehicles.
2. Yard Loading and Unloading: A "Vertical Handler" for Containers
The counterweight-type system allows for rapid deployment, eliminating the need for crawler cranes. A 20-ton container can be lifted and lowered into position in just 3 minutes, three times more efficient than a forklift and preventing scratches on the ground.
3. Rail Transfer: An "Aerial Ferryman" for Long Rails
The boom sweeps a 12-meter radius, transporting 15-ton rails from flatbed trucks to the yard. A dual-speed lift and electric trolley enable "in-flight flipping and precise palletizing," saving 80% of manual labor.
