Hydraulic cylinders, winches, or hydraulic lifting units used to raise and lower boats smoothly and synchronously.

Lifting Slings
High-strength, flexible slings positioned underneath the vessel hull. They distribute the load evenly and help prevent damage to the boat.

Hydraulic System
Consists of hydraulic pumps, cylinders, valves, hoses, hydraulic tanks, and related components for lifting and steering operations.

Traveling Mechanism
Heavy-duty wheels, drive motors, gearboxes, and axles that allow the crane to move with the vessel.

Steering System
Hydraulic or mechanical steering system allowing the crane to travel straight, turn, or move laterally according to the design.

Power Unit
Diesel engine or electric power system that supplies energy to the hydraulic and traveling systems.

Electrical Control System
Includes PLC/control panel, sensors, switches, cables, and control devices for coordinated crane operation.

Operator Control System
Cabin, pendant control, or wireless remote control for operating lifting, traveling, steering, and emergency functions.

Safety Protection Devices
Includes overload protection, lifting-limit protection, emergency stop, hydraulic pressure protection, travel limit protection, and warning alarms.

Wheel and Axle Assembly
Heavy-duty wheels and axles designed to withstand the high loads generated by a 120-ton vessel and the crane's own weight.

Emergency and Braking System
Braking devices and emergency stopping mechanisms used to safely control and stop crane movement when required.

Advantages of 120 Ton Boat Lifting Hoist Crane

High Lifting Capacity
With a rated capacity of 120 tons, the crane can safely handle large yachts, workboats, fishing vessels, ferries, and other heavy marine equipment.

Flexible Operation
The rubber-tired design allows the crane to travel freely around the shipyard or marina without requiring fixed rails.

Stable and Synchronized Lifting
A coordinated hydraulic lifting system provides balanced lifting at multiple points, reducing uneven loads and improving vessel stability.

Excellent Mobility
Heavy-duty wheels and a flexible steering system allow the crane to move, turn, and position vessels efficiently within limited working areas.

Hull Protection
Flexible lifting slings distribute the vessel's weight over a larger contact area, helping minimize stress and potential damage to the hull.

High Safety Performance
Overload protection, emergency stops, lifting limits, hydraulic protection, and other safety devices help ensure reliable operation.

Efficient Boat Handling
The crane can perform boat launching, hauling out, transportation, maintenance, repair, and storage operations, reducing handling time.

Customized Design
The lifting height, span, overall dimensions, sling arrangement, steering system, and control method can be customized according to vessel size and site requirements.

Suitable for Different Vessel Types
It can be used for yachts, fishing boats, patrol boats, workboats, passenger vessels, and other marine craft.

Reduced Infrastructure Requirements
Unlike fixed gantry cranes, a mobile boat hoist generally does not require a dedicated runway or permanent rail system, making it suitable for flexible shipyard layouts.

Application of 120 Ton Boat Lifting Hoist Crane

A 120 Ton Boat Lifting Hoist Crane is designed for heavy-duty vessel handling operations in shipyards, marinas, ports, and marine maintenance facilities.

Main Applications

Boat Launching and Hauling Out
Used to safely lift boats from the water and lower them back into the water for launching.

Yacht Handling
Suitable for lifting and transporting large yachts between the marina, maintenance area, and storage yard.

Ship Repair and Maintenance
Provides efficient vessel lifting for hull inspection, painting, cleaning, engine maintenance, and structural repairs.

Shipyard Operations
Used for moving newly built or repaired vessels between different working areas within a shipyard.

Boat Transportation
The mobile crane can carry vessels from the waterfront to dry storage or maintenance workshops.

Fishing Vessel Handling
Suitable for lifting and positioning fishing boats for routine inspection, repair, and maintenance.

Workboat and Patrol Boat Handling
Used for lifting service boats, patrol boats, harbor craft, and other commercial vessels.

Marine Equipment Installation
Can assist in positioning heavy marine equipment and components during vessel construction or refurbishment.

Dry Storage Operations
Used to transfer vessels from the water to land-based storage areas and accurately position them on support stands.

Marina and Port Facilities
Provides flexible vessel handling where frequent lifting and relocation of boats is required.
