Single Girder Overhead Crane: European Design for Unmatched Efficiency and Durability

The design, manufacturing, and inspection of the single girder overhead crane comply with relevant national standards, while also adopting certain foreign standards, such as FEM, DIN, and IEC. The main beam and end beam adopt a welded box-type beam structure, with the lower flange plate serving as the running track for the electric hoist. The main beam and end beam are connected using high-strength bolts, facilitating transportation and on-site installation. The hoisting mechanism employs a new type of electric hoist, featuring a compact structure and easy maintenance.

• Greater Durability: Lightweight design and low wheel pressure effectively improve the stress conditions of the workshop's crane beam system, extending the service life of main load-bearing components to a certain extent.
• Improved Efficiency: The entire crane adopts variable frequency speed control, ensuring smooth operation without impact, with slow speed for heavy loads and fast speed for light loads. 
• Low Headroom Height: Compact and innovative structure, small overall dimensions, and large working range.

Hoisting Mechanism Features

Utilizes imported German hoisting motors and reducers. The integrated compact design of the hoisting motor, reducer, drum, and lifting limit switch saves user space. The modular design enhances the mechanism’s reliability while effectively reducing maintenance time and costs.

The hoisting mechanism provides faster lifting speeds and a variety of pulley ratio options to choose from. The standard trolley traveling mechanism utilizes variable frequency control, reaching speeds of up to 20 meters per minute. This ensures minimal load sway during trolley movement and precise positioning, making it safe and reliable for hoisting delicate and valuable items.

Drum 

The drum is crafted from high-quality seamless steel pipes using CNC machining. After precision processing, the rope grooves on the drum, combined with a rope guide, effectively prevent rope loosening and tangling.

Wire Rope 

The wire rope is a high-strength imported wire rope with a nominal tensile strength of 2160 kN/mm², offering excellent safety and a long service life.

Rope Guide 

The standard rope guide is made from engineering plastic with high wear resistance and self-lubricating properties, significantly reducing wear on the wire rope—a critical load-bearing safety component—thereby enhancing the safety of the hoisting mechanism. Additionally, for varying operational conditions, a heavy-duty rope guide made from ductile cast iron is also available.

Hoisting Motor 

The hoisting mechanism employs a dual-winding squirrel-cage variable-pole motor, achieving a 1:6 fast-to-slow speed ratio. The motor housing is made of aluminum alloy through extrusion, providing excellent heat dissipation. A fan is installed at the motor’s end to enhance cooling performance. All hoisting motor windings are embedded with thermistors (or thermal switches) to prevent potential motor overheating. The motor has an insulation rating of Class F and a protection rating of IP54. For variable frequency hoisting motors, an encoder can be installed, typically mounted directly on the fan shaft end of the motor.

Technical Features: 

• Low starting current, high torque 
• Soft start with excellent acceleration performance 
• Long design service life 
• Technical parameters comply with FEM and HMI standards 
• High speed, low noise

Brake 

The hoisting motor is equipped with a dual-disc electromagnetic brake. The brake is integrated at the motor’s end and automatically engages when the motor loses power, preventing load slippage. The brake clearance is self-adjusting through the brake spring after initial setup, requiring no manual adjustment. When the brake pad thickness falls below the set value, an additional monitoring switch automatically triggers an alarm to prompt replacement. The dual-disc electromagnetic brake is safe and reliable, with a braking torque at least 1.8 times the motor’s rated torque. It can withstand up to 1 million braking cycles and requires no maintenance within its safe service life.

Technical Features: 

• Fast response, high reliability 
• Maintenance-free, self-adjusting 
• Dust-proof design, long service life

Reducer 

The reducer housing is made of aluminum alloy, offering light weight and corrosion resistance. The fully sealed housing contains semi-grease lubricant, ensuring all gears are adequately lubricated, with no need for lubricant replacement within the designed safe service life. Each gear, surface-hardened and precision-ground, ensures smooth operation of the reducer.

Technical Features: 

• Compact size, light weight 
• Smooth operation, low noise 
• Corrosion-resistant, maintenance-free

Safety Protection 

• Upper and Lower Limit Switch: The wire rope electric hoist employs a precise gear-driven limit switch. When the hook reaches the upper or lower limit position, it reliably cuts off the power circuit to stop the motor. 
• Overload Protector: The wire rope electric hoist is equipped with an electronic overload protector (with a safety monitor) to ensure the total lifting weight does not exceed the rated capacity of the crane. When the wire rope tension exceeds 105% of the rated value, the overload protection device automatically cuts off the hoisting circuit. 
• Safety Monitor: Depending on user requirements, it can perform multiple functions, including calculating the remaining safe working cycles of the hoisting mechanism, tracking cumulative hoisting operation time, recording cumulative overload occurrences, monitoring cumulative hoisting motor start times, providing motor overheating protection and alarms, overload protection and alarms, brake pad thickness alarms, and displaying fault information and maintenance prompts.

Comparison Between KUANGSHAN CRANE HD Single Girder Overhead Crane and LD Single Girder Overhead Crane

Compared with conventional single girder overhead cranes, the European-style single girder crane features lighter overall weight and lower wheel pressure; a compact structure with reduced energy consumption; modular design with intelligent operation; maintenance-free and user-friendly advantages.

5-Ton HD Type Overhead Crane for Ethiopian Market: Tailored Solution for 27m Span

This is a new customer referred to us by a long-term trusted client from Ethiopia, who has successfully purchased an HD-type single-girder 5-ton overhead crane from our company. Given the crane's span of up to 27 meters, the new customer naturally had concerns about the logistics of transporting such a long main beam. Long-distance transportation of such a large component poses significant challenges. To address this issue, our experienced engineering team devised an innovative solution. We decided to divide the main beam into three segments, each 11.8 meters long. Upon arrival at the installation site, our professional technicians used high-strength bolts and flange plates to precisely connect the segments at the cutting points. This connection method ensures extremely high strength at the joints. We conducted extensive testing and engineering analysis to guarantee the quality of these connections. As a result, the crane's integrity and performance remain unaffected, and the customer can rest assured that there will be no issues with the connection quality.
