QD type 75/20 - 100/20 ton hook bridge crane

The QD type 75/20 - 100/20 ton hook bridge crane is a high-performance and multi-functional double-girder bridge crane, suitable for various heavy-load and high-precision operation scenarios. The following is a detailed explanation of this model of crane:

1.Strong carrying capacity

The QD type 75/20 - 100/20 ton crane with a hook bridge is equipped with a powerful carrying capacity. The main hook can lift up to 75 - 100 tons, while the auxiliary hook can lift 20 tons. This design enables the crane to easily handle various large-tonnage operation requirements, such as lifting heavy machinery and steel structures.

2. High operational accuracy

This model of crane adopts advanced variable frequency speed regulation technology and encoder positioning system, ensuring that the positioning accuracy of the main crane and the trolley during operation is within ±2mm. At the same time, the lifting mechanism is equipped with a dual braking system, ensuring no impact during start and stop and good running stability.

3. Strong Function Expansion Capability

The QD type 75/20 - 100/20 ton hook bridge crane supports various function expansions, such as installing tension sensors to achieve precise weighing, and adding a 360° rotation mechanism to enable rotational lifting. These expanded functions enable the crane to better meet the operational requirements in various complex scenarios.

4. High environmental tolerance

This type of crane is equipped with high-strength materials and advanced protection technologies, ensuring stable operation even under harsh conditions. For instance, the motors and electrical cabinets are protected with IP54/IP65 ratings, providing dust-proof and water-proof protection; for metallurgical models, a high-temperature-resistant protective cover can be added, with a temperature resistance of ≥ 200℃; for chemical models, an anti-corrosion coating can be used, with resistance to weak acids and weak alkalis.

5. Wide application scenarios

The QD type 75/20 - 100/20 ton hook bridge crane is suitable for heavy object lifting and transportation needs in various scenarios. For example:

Heavy machinery manufacturing industry: Used for hoisting large machine tools and assembling components of construction machinery, requiring large lifting capacity and high precision alignment.

Metallurgical industry: Used for hoisting steel water tanks and transporting steel billets in the steel rolling workshop, needing to withstand high temperatures, dual-hook synchronization, and impact resistance.

Electric power industry: Used for installing/repairing steam turbines and generators in thermal power plants, and hoisting the runner of the water turbine in hydropower stations, requiring large span, high lifting height, and precise control.

Port and logistics hubs: Used for transporting overweight containers and hoisting large equipment, needing high-frequency operation, automated docking, and wind resistance stability.

6. Working principle

The working principle of the QD type 75/20 - 100/20 ton hook bridge crane includes steps such as lateral movement, longitudinal alignment, lifting the load, transportation and lowering, ensuring that the load can be accurately and safely transferred from one position to another.
