Description
The A-type double beam gantry crane is a heavy-duty gantry crane lifting equipment with a crane hook block. This type of gantry crane has two parallel beams. And it also has an electric trolley that can move along the beams to achieve horizontal material handling. There are two operation modes: ground and control room. The control room has two types: open and closed. It can be installed on the left or right side according to the actual situation. The entrance direction has two types: side and end, to meet the needs of users in various situations.

Advantages
When purchasing a marine travel lift for sale, it is recommended to conduct a professional evaluation in the following four areas:
Exceptional Load Stability
The A-shaped leg geometry and double parallel box-type main girders deliver superior bending and torsional rigidity, ensuring stability and safety even at maximum loads .
Massive Capacity & Wide Span
Rated from 5 up to 800 tons with spans of 18–35 meters, the dual-beam design provides wide-area coverage for large-scale logistics, steel yards, and port operations .
Built for Outdoor Harsh Conditions
Engineered for open-air environments, the crane features anti-corrosion coatings and robust wind load resistance (rated for 35 m/s storm-lock), with rail clamps and weatherproof components ensuring reliable operation in variable weather .
Precision Control & Low Maintenance
Variable frequency drive (VFD) with PLC enables smooth, energy-efficient control and precise positioning (up to ±1mm on advanced models). Modular design, forged wheels, and durable components reduce maintenance and extend service life .
