HY Crane MG-type Dam Top Gantry Crane: The Intelligent Steel Line of Defense for Water Conservancy P

In the construction of water conservancy projects and the safe operation system of hydropower stations, the dam top gantry crane is an indispensable core equipment, undertaking the key missions of precise gate opening/closing and efficient equipment hoisting. With over 30 years of deep cultivation in the hoisting industry, HY Crane has created the MG-type dam top gantry crane relying on national Class A special equipment manufacturing qualification and a number of patented technologies. Boasting core advantages of precision, intelligence, safety and adaptability, it serves as the "Air Commander" for hydropower station operations and builds a solid steel line of defense for national key projects such as energy.

Three Core Capabilities for Efficient Operation

The MG-type dam top gantry crane optimizes structural design, operation mode and operation adaptability in an all-round way, building three core capabilities to fully meet the diverse operation needs of hydropower stations and greatly improve operation efficiency and precision.
Precision Gate Control System
Dual main girder box welding structure with π-shaped outrigger design, increasing gantry rigidity by 40% and enhancing bending resistance significantly, ensuring stable operation in extreme temperatures from -25℃ to 40℃. The main hoisting mechanism is equipped with a high-precision encoder and PLC control system, controlling the gate opening/closing error within ±2mm, and perfectly adapting to the operation of all gate types including flat gates, arc gates and accident maintenance gates.
Intelligent Slewing Hoisting
Original dual-system collaborative operation mode: the main hoisting trolley is responsible for lifting large gates with a maximum lifting capacity of 320 tons; the auxiliary hoisting slewing crane can flexibly lift small equipment such as hydraulic hanging beams and maintenance tools. A single machine realizes dual functions of "gate opening/closing + hoisting", reducing redundant equipment investment.
Adaptive Track System
The cart running mechanism supports dual modes of horizontal movement and vertical rail change, with a customizable span of 7.5-31.5 meters to adapt to different dam top structures. The wheel set adopts a combination of cylindrical cast steel wheels and bumpers, with a running speed of 45m/min and vibration 20% lower than the industry standard, greatly reducing track wear.

Hard-Core Technology for All-Round Safety Protection

Five-Layer Safety Protection System
^{Real-time load monitoring:} Electronic weighing system linked with overload protector, automatically cutting off power when overload is detected
^{Double-channel limit protection:} Lifting height limiter + cart travel limiter, building a dual anti-collision mechanism
^{Wind-resistant hook stabilization design:} Gantry structure passing wind pressure simulation test, withstanding level 8 strong winds in inland areas
^{Emergency brake backup:} Block brake + electromagnetic power-off protection, locking the load within 2 seconds in case of sudden power failure
^{Anti-drop hook device:} Gravity-type safety hook to ensure zero accidental falling of spreaders

Intelligent "Dual-Brain" Control System

Remote central control: One-click gate opening/closing, speed adjustment and fault diagnosis via central control room PLC system, with real-time data uploaded to the cloud
Local fine control: Driver's cab equipped with rain shelter and panoramic glass, supporting manual micro-operation to meet the refined operation needs under special working conditions

Multi-Scene Application for Hydropower Stations

The MG-type dam top gantry crane is widely applicable to all core operation scenarios of hydropower stations with its excellent comprehensive performance:
✅ Regular opening/closing and emergency lowering of various gates of hydropower station dams
✅ Overhaul hoisting and equipment installation of tailwater platforms
✅ Placement and recovery of underwater hydraulic automatic hanging beams
✅ Transfer and maintenance of dam top equipment and accessories
