Wind power is one of the main sources for electricity generation in Netherland. Using wind turbine generator to generate electricity is not only environmental-friendly but also can adjust one country’s energy structure and improve people’s life quality. Reducing carbon emission is not only Netherland’s wish but also the goal of the whole world, and Netherland has set a good example for the world in renewable energy development. Actually, 75% of Netherland trains were driven by wind power till last year, and the percentage reached 100% on January 1st of this year. The crawler cranes is an indispensable device when installing a wind mill.

The wind turbine generator appeared in the 1890s and developed fast since 1980s. In the past years, the diameter of the rotor blade kept increasing and the rated power kept improving, being more and more widely used in industrial applications. More and more countries in the world take deep interest in the wind resource development, which will make the wind power more popularized in the future.

Hydraulic Roller VS Mechanical Roller, which is the King of Road Machinery?

Road roller can be divided into hydraulic type and mechanical type. Discussions have been generated about the comparison of the two types in different aspects. The comparison mainly focuses on efficiency, safety, environmental protection, maintenance, price, reliability and comfort.

The mechanical roller has no front wheel drive and its working speed is fixed. The hydraulic one adopts full-wheel drive, which allocates more power to the vibrating drum, improving the compactness and reducing the compacting times, having more advantages in improving efficiency. And the hydraulic type needs no stop in the travelling process, improving 10% in efficiency than the traditional mechanical one. For safety, braking is an important factor that decides whether the machine can be stopped immediately once emergency happened. The brake of the hydraulic one combines with the joystick and can be locked when emergency happened. The brake and joystick of the mechanical one is separated, which may cost more time for the operator to stop the machine under urgent situation. Thus, the hydraulic roller has higher safety than the mechanical one, especially in mountainous area and dam construction. Also, the hydraulic type does a better job in heat dissipation than the mechanical one. The hydraulic type can be used in extreme temperature ranging from -40℃ to 60℃. And the hydraulic type is easier to be maintained.

Although the hydraulic roller has higher price than the mechanical one, its advantages in high efficiency, high reliability, environmental protection, safety and ease of maintenance are obvious. All of the industry experts, representatives and media believe that the hydraulic type has huge market potential in the future.

The reachstacker consists of three parts including chassis, telescopic boom and container lifting appliances. The chassis system consists of engine, gearbox, steering system, cab, car frame and wheels. The telescopic boom consists of telescopic cylinder, derricking press and boom frame. The container lifting appliance consists of rotary device, upper-carriage, connecting carriage, under-carriage, telescopic cylinder and so on.

 

How does the container reach stacker perform its daily duty? First, the stacker will discharge the containers from the truck. Second, stack the containers in the yard. Third, grad the containers and transport them to the designated place. Fourth, put the containers into the truck. When lifting the containers, the machine should be close to the containers as much as possible to keep the machine in a stable condition. The port machinery containers should be lifted straight, not slant. The distance between the container and the ground should be as low as possible when the stacker is travelling and the speed should not exceed 5 km/h, the travelling distance should not more than 100 meters. Sudden turn, over-speed and urgent braking are forbidden except special circumstances.
