28th March, the 65t - 3.5m hydraulic luffing gantry crane customized by Maxtech has completed on-site assembly and is ready for shipment to Saud. This achievement marks a significant progress in the cooperation project between the two parties, and the equipment is about to be put into practical use.
This gantry crane is designed specifically for lifting heavy objects and other items on ships. It has excellent performance parameters. Its safe working load reaches 65t, the maximum lifting height is 4.1m, the effective travel of the hook from the deck is greater than 3.8m, and the lifting speed is 5m/min. The horizontal luffing distance (the hook beyond the ship's side) is approximately 2500mm, enabling it to efficiently complete various lifting tasks during ship operations. Moreover, this gantry crane can adapt to the marine environment and can operate stably under conditions of -10°C to +55°C and a relative humidity of 90%. The allowable tilt of the ship during operation is heel ≤ 5° and trim ≤ 10°, demonstrating strong environmental adaptability.
The follow below is the technical parameter of A-frame gantry crane:
| main technical parameter | |
| SWL | 65t |
| Max hoisting height | 4.1m² |
| Hoisting speed | 5m/min |
| Hoisting speed | ≈2500mm² |
| Back to the side of the hook to the side | ~3850mm |
| Amplitude variation time | 120s |
| Distance between the center of the two legs | 3.5m² |
| Motor type | Y280S - 4 - H - B35 |
| Power | 75 kW×2 |
| Working system | S6 - 40% |
| Voltage | 380V 50Hz 3ph |
| Level of protection | IP56 |
| Allowable tilt of ship | heel≤5°/trim≤10° |
In terms of technical design, this port gantry crane has many highlights. It adopts a control method combining local operation and remote centralized control, which is convenient for operation. The A - Frame structure and power pack are designed with forward - looking features, leaving room for future upgrades. In the future, by adding 2 telescopic cylinders inside the A-frame legs of the portal post, the horizontal range can be extended to approximately 4750mm, and the maximum lifting height can reach 7500mm. The safety system is also very comprehensive, with multiple protections such as automatic luffing protection devices, hydraulic safety valves, and luffing limiters to ensure operation safety.
During the manufacturing process, MAXTECH strictly adhered to the latest specifications and requirements of the BV Classification Society. High - quality accessories were selected. For example, hydraulic motors, oil hydraulic pumps, motors, etc. are all from well - known brands, ensuring the reliability and stability of the equipment. The surfaces of all structural components are sand - blasted to Sa2.5 level, and domestic well - known brand paints are used for painting. The painting process is carried out in strict accordance with the painting process specifications to ensure the anti - corrosion performance of the equipment.
At present, the gantry crane has completed on - site assembly and is ready to be shipped to its destination. Before shipment, it has undergone factory pre - installation inspections and various tests, including performance tests, emergency stop confirmations, and manual release tests of brakes, to ensure that the equipment is in good condition when delivered for use. According to the after - sales service agreement, our company will dispatch 1 - 2 engineers to the site for 15 days of free installation and commissioning guidance to help the equipment be put into use smoothly.
