>>>Introduction
Tower crane has a horizontal jib frame, a jib-trolley radius-changing mechanism and a hydraulic self-raising mechanism.  It is original in design, reliable in operation and satisfactory in shape.  Equipped with all necessary safety devices, these cranes show a good speed-control capacity, satisfactory operating stability and high work efficiency. Â
Top kits tower crane is widely used in infrastructure construction ,high-speed rail,oil fields,large ports,nuclear power,wind power and other construction fields.
>>>Feature
1.Suitable for all kinds of construction project and can work under all kinds of work condition.
 2.It has high working speed, good speed-adjusting performance, steady operation and high  efficiency.
 3.The crane has complete set of safety devices, which can guarantee the safe and high efficienct  operation of the equipment.
 4.Three-speed motor and mono-speed ratio decelerator are applied in the lifting struction, which  enables heavy load low speed and light load high speed.
 5.Planet gear decelerator is applied in the circumgy rating structure, together with moment-limiting  hydraulic coupler, which can realize high load capacity, steady starting and reliable operation.Â

Knife Gate Valves are usually used for pulp/paper and mining industries.
Knife Gate Valves are named for its sharp, knife-like disc, which could
be used for cutting medium. The groove around the seat permits the gate
to push particles aside and prevents clogging. When the valve is open,
the flow cleans the groove. Seat is outside the flow area resulting in
higher flow coefficient with minimum pressure drop.
