The amount of energy absorbed is the main technical performance indicators fender instruments. With the ship's tonnage growth, berthing operations, ship collision energy contact quay or other ships also doubled. Huge collision energy must rely on the contact area on the fender and enough to absorb sufficient deformation. Our ship fender use compressed air as the buffer medium to absorb ship impact energy and have good elasticity. (4)Floating performance is good, not subject to tidal influence, fender can be maintained in the ideal level Pneumatic fenders floating on the water surface (more than 50% of the volume), along with the change of position is not relative to the tidal fluctuation. Especially the ship as the waves rolling, cylindrical inflatable fenders with rolling, the friction force is very small. So it will not damage the coating surface of the hull, and also decrease the moving.
The Single Girder Gantry Crane is mainly used outdoor working site for hoisting and moving of materials. It has the advantages of simple structure, convenient transportation and installation, light self-weight, and the main girder is mostly a derailed box-shaped frame structure. Single girder Gantry Crane is usually used for lifting weight ≤ 50 t and the span ≤ 35 m.
Single girder gantry crane legs can be L- and C-type. The L-type single girder gantry crane is easy to install, stable structure, light slef-weight. However, the space for lifting cargo through the legs is relatively small. The C-shaped legs are made of a slanted or curved shape with the purpose of having a large lateral space for the goods to pass through the legs.
Weihua also provide European standard (FEM and DIN standard) single girder gantry crane which has the advantages of compact structure design, light self-weight, smooth running, world class brands components and electrics, less noise, less consumption, large working space, precise positioning, etc. The Electric Hoist is also FEM and DIN standard.

2.Product description:
Penumatic rubber fender with chain protection
(1) High energy absorption
(2) Ultra low back pressure
The inside air of  pneumatic fenders is low pressure gas, the internal pressure increase is very limited during compression deformation. Due to the large contact area, unit pressure acting on the ship hull surface is very low, compared with other fender instruments, is not the common low back pressure.
(3) Inclined contact, good adaptability
Ship must have certain angle which have the possibility of contacting the side of the shore. As the inclined interface of sea inflatable fender, its adaptability is much higher than other fender.
