[Technology] wind farm power line route selection (overhead)
As a part of wind farm design, the choice of route is crucial to the overall design of the line. Correct choice of route or not will affect whether the circuit design is safe, economical and reasonable. The principle of path selection should follow the following points: 1, the path should be short. This is one of the determinants of line engineering economics. Short means that the path to be as straightforward as possible to avoid winding roads, short lines, the project cost is low, less...
Liebherr offshore cranes deliver the largest mobile dock overhead crane in the Caribbean
Recently, Liebherr Maritime Crane delivered the largest mobile terminal overhead crane in the Caribbean to Kingston Wharves of Jamaica. The LHM 600 mobile terminal overhead crane will be equipped with an extended tower to facilitate the handling of large container ships and very large rear Panamax container ships. To further increase operational efficiency, Kingston Wharves ordered the LHM 600 mobile wharf overhead crane from Liebherr Offshore Cranes. It is reported that the new mobile terminal...

Accidents and Prevention of 10kv Overhead Insulated Conductor for Overhead Lines
According to operating experience, common accidents of 10kV overhead lines are as follows: 1. Lightning Accidents There are many kinds of accidents caused by lightning strikes on 10kV overhead lines. There are insulator breakdowns or bursts, broken wires, and transformers. Lightning strike accidents, although there is a major relationship with the objective causes of lightning strike lines, and equipment defects are also of great concern, the main reasons for the analysis of its equipment are:...
LHM800 mobile dock overhead crane, Liebherr new container handling giant
The Liebherr LHM800 is like a lifting giant, providing a new opportunity for the loading and unloading of many ports in the world. The mobile is light and flexible, easy to operate, and has a heavy lifting capacity. LHM has brought many surprises to the port loading and unloading teams since its launch. The new LHM800 mobile terminal has a lifting capacity of 308 tons, which exceeds the lifting capacity of the brand LHM600 by nearly 100 tons. In the field of container configuration, the LHM800...
Crane maintenance is divided into five levels - Haikou gantry crane supply - Haikou crane manufacturers
Crane maintenance is a topic that the owners are very concerned about. The industry can probably say a few words, but many people will be dumbfounded when they encounter crane maintenance work. As a large machine, crane maintenance is not a trivial matter, and it is no wonder that everyone will have a headache. The author believes that it is not really a matter of knowing how to repair cranes, even if it can solve some crane problems. Because there is something more important than the simple...
Introduction and principle analysis
The hoisting machinery that has been in contact for so long has compiled so much mechanical technical information. We will find that there is no comprehensive understanding of the overall structural composition of some lifting machinery, and there is a lack of understanding of some operating principles. In this case, Puqi lifts the auto repair school to conduct a comprehensive introduction. The obvious difference between a crane and other general machines is the combination of large, movable...
4 Methods For Crane Maintenance
First, since the crane maintenance is a special vehicle, the operator should receive training and guidance, have a full understanding of the structure and performance of the machine, and obtain certain operational and maintenance experience before operating the machine. The product maintenance and repair instructions provided by the manufacturer are the necessary information for the operator to operate the equipment. Before operating the machine, be sure to read the maintenance instructions and...

Why can't the overhead crane reverse the emergency brake
The body of the bridge crane is very heavy, and the inertia is very large during operation. When the bridge crane is running normally, the emergency brake is reversed immediately, which will cause the entire operating mechanism to generate a large amount of torque and damage the transmission system. In severe cases, the transmission shaft may be broken, and the car body may be skewed and deformed. It may also have a violent impact on the gear coupling system, damage the gear, and cause...
