B. Support Legs (End Carriages)

Here's a quick breakdown of what you're likely referring to:
🏗 1200-Ton Boat Lift Gantry Crane
Capacity: 1200 tons - very heavy-duty, used for lifting ships or large boats out of the water.

Structure: Consists of a large gantry frame, hydraulic or electric lifting mechanisms, and motorized end carriages for movement.

🔩 End Carriages
These are the driven wheels and supporting frame assemblies at each end of the gantry crane.

Function: Support the gantry structure and enable horizontal travel along rails or a concrete runway.

Key Features:

Heavy-duty wheels (often rubber-tired or steel-wheeled, depending on application).

Motorized drive systems.

Steering and braking systems (especially for mobile marine lifts).

Shock absorption and alignment systems for smooth travel.

🛠 Technical Considerations
For a 1200-ton capacity, the end carriages would need:

Multiple wheel bogies per side (typically 8–20 wheels per side depending on the weight distribution).

Synchronized motors with precise control systems.

Heavy-duty gearboxes and load-sensing hydraulic or electric drives.

Weather resistance and anti-corrosion treatment (marine environment).

Alignment systems (to reduce wear and maintain stability over uneven terrain or track misalignment).

 

 

C. Base Frame (Runway System)

🔧 Components of the Runway System
Gantry Crane Structure:

Capacity: 1200 tons

Configuration: Typically a U-frame or straddle-type gantry crane

Mobility: Equipped with wheels for movement along the runway

Runway System:

Track Rails: Heavy-duty steel rails installed on reinforced concrete paths

Ground Beams/Runway Beams: Embedded or surface-mounted beams that support the crane's wheels

Foundations: Deep concrete footings to bear the massive weight during lifting and moving

Drive and Steering System:

Electric or Hydraulic Motors for movement

Steering Mechanism for turning and alignment

Synchronisation System to ensure coordinated movement of all wheels

Control System:

Remote Control or Cabin Operation

Safety Features: Anti-collision, overload protection, emergency stops

 

 

2. Lifting & Hoisting Mechanism

1. Main Lifting System
Configuration: Multi-point lifting system, usually 4 to 16 lifting points, evenly distributed to balance the boat's weight.

Hoisting Winches: Heavy-duty electric or hydraulic winches control each lifting point, often synchronized via a central control system.

Ropes or Belts: Uses high-strength wire ropes or polyester lifting belts (soft slings) to cradle the hull, minimizing hull damage.

Load Sensors: Real-time feedback ensures balanced lifting and prevents overloads at individual points.

 

B.

Synchronization System
PLC Control System: Ensures all lifting points move simultaneously, avoiding hull stress.

Feedback Mechanisms: Load cells and position sensors continuously monitor tension and position.

Auto-Leveling: Automatically adjusts hoisting speeds to compensate for uneven loads or boat asymmetry.

C.

Drive & Power
Power Source: Usually electric (with cable reel system or battery-powered), or diesel-hydraulic for mobile types.

Hydraulic Cylinders (if applicable): Some designs use large hydraulic rams for vertical lift.

 

3.

Safety Features
Overload Protection: Automatically halts lifting if weight exceeds limit.

Emergency Stop System: Instant shutdown in case of anomaly.

Manual Override: For precise manual control in emergencies.
