China Supplier QD Double Girder Crane – Heavy Duty Overhead Lifting Solution

Product Description

The QD-Type 5~50/10t Hook Bridge Crane is a powerful and adaptable overhead lifting solution meticulously engineered for demanding material handling applications in industrial settings such as workshops, warehouses, steel mills, and logistics hubs. Equipped with a dual-hoist configuration (5-50t main hook and 10t auxiliary hook), this crane offers an exceptional blend of high load capacity and precision control, making it the ideal choice for lifting, transporting, and positioning heavy loads with unparalleled efficiency and utmost safety.

1. The QD model overhead crane with hook is primarily designed for use within indoor workshops. It is categorized into two distinct working classes: A5 and A6, depending on the operational grade and load-up conditions.
2. The crane offers three distinct entry methods to the cabin platform: from the side, from the end, and from the top.
3. The cabin can be securely positioned at either the left or right end, providing flexibility to suit various operational setups.
4. For electrical conduction, the crane can utilize either a safe slide wire or angle iron, with the flexibility of placing it on the same side as the cab or on the opposite side, according to requirements.
5. All crane operations are executed entirely from within the cabin, ensuring comprehensive control.
