Gate valve is used as a cut-off medium, the entire circulation through the fully open, this time the pressure loss of medium operation minimum. Gate valve is usually applied to do not often need to open and close, and keep the gate fully open or fully closed conditions. Not suitable for use as a regulator or throttling. For high-speed flow media, the gate may cause gate vibration when the gate is open partially, and the vibration may damage the sealing surface of the gate and valve seat, which can cause the gate to suffer erosion of the medium. The main difference from the structural form is the form of the sealing element used. According to the form of the sealing element, the gate valve is often divided into several different types, such as wedge gate valve, parallel gate valve, parallel double gate gate valve, wedge double gate gate and the like. The most common forms are wedge gate valves and parallel gate valves.

A Semi-Gantry Crane is a Gantry Crane with only one side supporting leg, and the other side is supported on the horizontal structure such as workshop wall. The leg side is traveling on rail tracks laid on the ground, while the other side is traveling on the tracks on the supporting structure.


Single Girder Semi Gantry Crane


The main beam of a semi-gantry crane can be a double-girder or a single girder, and the hoisting mechanism can be an Wire Rope Electric Hoist or a hoist/winch on a trolley. The semi-gantry crane is usually used outdoors, also indoors at a large workshop for handling working pieces, bulk mateirals, machines, steel products, scraps, containers, etc.

Semi Gantry Crane Single Girder With Hoist


Features of Semi-Gantry Crane:


1. All steel plates are processed by pretreatment production line: Shot blasting – Painting – Paint Drying, Eliminate stress in steel plate, and increase Adhesion between paint and steel plate and anti-corrosion.

2. Adopt Germany Messer plasma CNC cutting machine to cut steel plate with high efficiency and accuracy (±1mm).

3. Rolling drum with seamless steel with pressure 1250t. Auto welding and heavy duty CNC lathe for processing.

4. Double gun gantry submerged arc welding for end beam processing.

5. Welding robot for main beam welding, MAG welding for inside seam welding, Ar+CO2 Mixed protective gas.

6. X-ray flaw detection, Ultrasonic flaw detection for welding seam.

7. High temperature quenching and quenching and tempering treatment for wheels to release internal stress.

8. Annealing furnace (1000mm*4000mm*4000mm) for annealing of trolley, rolling drum, balancing beam, wheel group and spreader.

9. Anti-sway system can be equipped according to customers' requirement.
