I. The innovative features of this crane
1、 The technical challenges overcome by this design:
The lifting mechanism is arranged on the inner side of the trolley end beam and main beam. ;
The large vehicle's running mechanism adopts a direct connection between the bogie and main beam, replacing the end beams. ;
The hook beam and pulley shaft are integrated into one, minimizing the overall height from the bottom of the hook to the top of the pulley.
2 • Solutions for technical workstations.
The trolley-type ultra-clearance overhead gantry crane features an ultra-clearance design that minimizes the combined height required for both the trolley and main bridge movements, while simultaneously maximizing the lifting height under identical conditions. This innovative structure is ideal for applications where factory space is limited—enabling use in scenarios where conventional overhead cranes simply cannot operate. To achieve this, three key technical measures have been implemented:
The lifting mechanism is arranged on the inner side of the trolley end beam and main beam, with its upper surface positioned lower than the top of the trolley end beam—effectively reducing the overall height of the crane.
The large vehicle's running mechanism features a direct connection between the bogie and the main beam, with both components aligned flush—replacing the conventional end beams. ; The workshop utilizes tie rods for connection and features heavy-duty, integrated wheels. This structural design distributes the load across multiple wheel contact points, reducing the maximum force acting on each individual column—allowing the steel-structure workshop columns to remain un-reinforced.
The hook assembly features a compact, directly connected mountain-type hook, where the hook beam and pulley shaft are integrated into a single unit. This design minimizes the overall height from the bottom of the hook to the top of the pulley, allowing for the maximum possible lifting height under the same conditions.
II. Comparative and Overall Analysis of the Scientific Merit and Creativity of This Achievement
According to the "Technology Novelty Search Report," it can be determined that the ultra-clearance design adopted in the trolley-type, ultra-clean overhead hook bridge crane is as follows: 1. The lifting mechanism is arranged on the inner side of the trolley end beam and main beam. ;2. The large vehicle's running mechanism adopts a direct connection between the bogie and main beam, replacing the end beams. ;3. The hook beam and pulley shaft are integrated into one, minimizing the overall height from the bottom of the hook to the top of the pulley.
