100 Ton Marine Travel Lift for Boat Handling
Introduction
The boat hoist yacht lifting gantry crane is a specially designed piece of equipment composed of a main structure, traveling wheel block, hoisting mechanism, steering system, hydraulic transmission system, and electric control unit. Its unique “U”-shaped frame allows it to lift and transport boats taller than the crane itself, ensuring flexible and safe handling. Depending on customer requirements, the boat gantry crane can lift and move yachts of various tonnages from shore to water or vice versa, making it ideal for launching and maintenance operations. The soft, durable lifting belts protect the hull from damage, while the PLC-controlled electrical system with frequency adjustment ensures smooth, precise, and efficient operation, allowing for tight and orderly boat placement.
Structural Design
Structural Strength and Rigidity:
The boat gantry crane is designed with exceptional strength and stiffness to handle heavy boats and yachts safely. Their main frame and girders are carefully engineered to endure maximum working loads without excessive deflection or deformation. In shipyard applications, a double-girder structure is often adopted to enhance overall load-bearing capacity and stability, ensuring smooth and balanced operation even during long-term, high-frequency use.
Load Distribution:
Proper load distribution is a core aspect of the design. The marine travel lift ensures that lifting forces are evenly transmitted through the frame and distributed across the wheels or rails. This uniform load transfer minimizes localized stress, effectively reducing the risk of fatigue cracks or structural failure.
Fatigue Resistance:
Operating in marine environments means that the boat gantry crane must sustain continuous cyclic loading. Therefore, each structural component is optimized for fatigue resistance, extending the equipment’s operational lifespan and reliability under demanding working conditions.
Corrosion Protection:
The marine travel lift uses high-strength, corrosion-resistant steel combined with multi-layer protective coatings, such as epoxy primer and marine-grade paint, to withstand harsh saltwater exposure. Additionally, its structure is designed for easy inspection and maintenance, allowing quick access to corrosion-prone areas and ensuring long-term durability.
Configurations
Automatic Rectify Deviation Control: The boat gantry crane is equipped with an intelligent deviation correction system that ensures stable straight-line travel, even under uneven load conditions or rough ground, improving overall precision and safety.
Weight Overload Protection Device: This function automatically detects excessive load and stops lifting operations to prevent mechanical damage and ensure the long-term reliability of the boat gantry crane.
High-Quality Polyurethane Buffer: Installed at both ends of the traveling system, these buffers absorb impact energy, reducing vibration and protecting both the crane structure and the yacht.
Phase and Voltage Protection: The marine travel lift includes phase loss and low-voltage protection, ensuring smooth operation and preventing electrical malfunctions.
Limit Switches: Lifting, cross traveling, and long traveling limit switches accurately control motion range, avoiding overtravel and enhancing safety during operation.
Emergency Stop and Current Overload Protection: The marine travel lift features a fast-response emergency stop button and overload protection circuit to ensure immediate shutdown in case of abnormal operation.
Lighting and Alarm System: Equipped with LED lighting and audible-visual alarms, the system provides clear visibility and timely alerts during nighttime or complex operations, enhancing both efficiency and safety.
