Chain Hoist is a small capacity hoist with the chain as the hoisting sling. It can be a munual type chain hoist or a electric chain hoist. The chain hoist can be mounted on a I/H beam steel, Suspension Crane, portal Gantry Crane, Jib Crane or Overhead Crane, etc. for lifting light weight goods.
Manual chain hoist is simple to use with simple structure. Electric chain hoist can be a Europ standard electric chain hoist or a sanitary chain hoist which is fabricated according to European FEM and Germany DIN standard with modularized design of motor and reducer.
Capacity: 0.1t ~ 5t
Lift height: 3m ~ 8m
Lift speed: 10m/min
Packing: wooden case, leather, reinforced bar, etc.

Application Analysis of Adjustable Combined Valve Gate Technology
First, the technical background: the existing valve in the valve body, valve cover and the components are intact, only a slight deformation or corrosion of the sealing surface, the valve can not be used. Repair these valves non-professional factory does not work, resulting in great waste. Therefore, the valve unit is expected to use is: valve seat, valve plate sealing surface is not easy to deformation, corrosion-resistant, vulnerable sealing material can be changed. Valve plate in the opening and closing with the sealing surface do not have friction or minimize friction. Second, the purpose of the invention: to solve the valve seat and the valve plate sealing surface corrosion or deformation, the valve plate can automatically compensate and compress the sealing surface and the pressure between the valve and the valve automatically balance the problem, to solve the soft sealing material by friction and damage the seal Face of the problem, due to the sealing of the valve can be changed, greatly increasing the service life of the valve. Third, the practical range: diameter φ50-φ400mm, pressure 2.5-4.0MPa, less than 200 ℃ of all kinds of liquid at room temperature. Fourth, the technical program: The valve is a double parallel gate valve, inlet seal, the inlet valve plate by the seal cover and force relief valve plate composed of the main seal gate. The sealing sleeve moves synchronously with the unloading valve plate but it is not connected. The pipe pressure is transmitted to the valve seat on the outlet side through the unloading valve plate and the leveling arm, which greatly improves the bonding force of the soft sealing surface. The valve plate is covered with a corrosion-resistant rubber gland. Soft sealing material in the process of opening and closing, with the valve seat to maintain a certain distance, so that the soft sealing material in non-friction non-pressure environment work. The gland isolates the fluid being delivered in the pipe from the parts inside the spool to protect it from fluid corrosion and impurities. This valve sealing material replacement is very convenient, so the service life is more than 5 times the general valve.
