QD type 300/40~350/75 ton hook bridge crane

The QD type 300/40~350/75 ton hook bridge crane is a high-performance, high-capacity double-girder bridge crane, suitable for various heavy-load and high-precision operation scenarios. The following is a detailed interpretation of this model of crane:

1. Strong carrying capacity

The QD type 300/40~350/75 ton hook bridge crane has a powerful carrying capacity. The main hook lifting capacity is 300~350 tons, and the auxiliary hook lifting capacity is 40~75 tons. This design enables the crane to easily handle various heavy-load operation requirements, such as lifting heavy machinery and steel structures.

2. High running accuracy

This model of crane adopts advanced variable frequency speed regulation technology and encoder positioning system to ensure the positioning accuracy of the main and small cranes during operation reaches ±2mm. At the same time, the lifting mechanism is equipped with a dual braking system to ensure no impact during start-up and stop, and good running stability.

3. Strong function expansion capability

The QD type 300/40~350/75 ton hook bridge crane supports various function expansions, such as installing tension sensors to achieve precise weighing, and installing 360° rotation mechanism to achieve rotating lifting. These expansion functions enable the crane to better adapt to various complex scenarios' operation requirements.

4. High environmental tolerance

This model of crane uses high-strength materials and advanced protection technologies to ensure stable operation in harsh working conditions. For example, the motor and electrical cabinet use IP54/IP65 protection grades, dustproof and waterproof splash-proof; metallurgical models can be equipped with high-temperature protection covers, with a temperature resistance of ≥200℃; chemical models can use anti-corrosion coatings, with a resistance to weak acids and weak alkalis.

5. Wide application scenarios

The QD type 300/40~350/75 ton hook bridge crane is suitable for various scenarios' heavy object lifting and transportation needs. 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 high temperature resistance, dual-hook synchronization, and impact resistance.

· 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.

· Ports 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 300/40 - 350/75 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.
