25T Gantry Crane for Handling Precast Concrete in Construction Company

A batch of Model MHII double girder gantry cranes, manufactured by Huayuan Crane, has been successfully installed at a leading construction material company. This Euro-style crane, equipped with a 25-ton electric wire rope hoist crab, is set to revolutionize the handling of prefabricated concrete structural components and molds.

Features of Euro-style Gantry Crane:

• The overall height of Euro-style double girder gantry crane is reduced by 20% to 25% compared to traditional cranes, with a weight reduction of 20% to 30%.

• The maximum wheel pressure is reduced by 15% to 20%.

• The compact design of the crane expands the available working area.

• The lightweight structure helps reduce construction costs.

• All crane components are designed according to standardized modular principles, making product assembly easier.

• The independent modular design simplifies transportation.

• Standardized modular production ensures product quality consistency and shortens delivery times.

• The steel plates undergo sandblasting pretreatment, achieving a surface quality of Sa2.5.

• A digital cutting machine is used to precisely cut the web plates, ensuring smooth and accurate camber curves.

• The main welding seams are processed using automatic arc welding, with ultrasonic and X-ray nondestructive testing for quality assurance.

• The crane and trolley frames are processed with a floor-type boring machine to ensure precise flatness of the machine sides.

• The safety monitoring system includes an overload limiter, which displays load values on the monitor and alerts the operator to prevent overload situations.

• Before operation, the controller performs a self-check, testing power voltage, phase defaults, the effectiveness of safety devices, and the zero position of the buttons.

• The crane uses imported brakes from Germany, with a braking force of no less than 2160N/mm² and a safety factor of at least 5.

• The motor is imported with an F insulation rating and an IP54 protection grade. It also features overheating and alarm functions. The motor cover is made of aluminum alloy for better heat dissipation.

• The crane is equipped with a German-imported reducer, featuring hardened face gears that improve bearing capacity and provide superior shell sealing to prevent grease leakage.

• The main electrical components are from internationally recognized brands such as Schneider, Siemens, and ABB. The electric control box has a protection rating of at least IP54.

• The wheels are forged from 65Mn alloy steel, offering excellent abrasion resistance, fatigue resistance, and a long service life. Domestic options are available based on customer needs.

• The crane’s total power consumption is up to 30% lower than that of traditional cranes.

• The integrated multi-in-one transmission system reduces intermediate components, resulting in higher transmission efficiency.

• The crane utilizes frequency control with a high-low speed ratio of 1:10, increasing work efficiency by over 20%.

• The “Maintenance-free + Easy Maintenance” design philosophy helps reduce customer maintenance costs.

• The latest Euro-style Crane model incorporates advanced processing technology and premium imported components, significantly reducing its failure rate and helping customers lower operational costs.

• The crane's safety monitoring system features a "black box" that records every operation, ensuring reliable data tracking.

• The crane can be equipped with world-leading electrical anti-sway technology, enabling precise positioning.

• With cutting-edge electrical control technology, the FEM/DIN gantry crane can operate in both semi-automatic and fully automatic lifting modes, transforming it into a "lifting robot."
