According to the power transmission method of hoist, dividends can be divided into mechanical transmission and hydraulic transmission. Mechanical transmission is divided into belt transmission, chain transmission, gear transmission and combined transmission. Hydraulic transmission can be divided into hydraulic transmission and hydraulic transmission, that is, hydraulic hoist. 3. When the gate is connected with the hoist, it can be divided into flexible, rigid and semi-rigid connections. The equipment debugging technology and the knowledge of using self-care should also be vigorously promoted. The utility model is suitable for water conservancy, hydropower, Park construction, aquaculture and farmland construction projects. The self-locking function is good, and the gate can stay in any position. There are two kinds of shakers, manual and electric, which should not be used. Two Shakers above 15T are needed. According to customer's requirements, electronic altimeter can be distributed, and it can be controlled on site and in short range or centralized. In view of the construction units and operation management departments, this technology and knowledge should be popularized in order to ensure the quality of the project and promote the benefits of the project. Vertical gate 360 degrees into the groove, adjust the pad block (not allowed to pad the cross beam) on the bottom pad of the lateral vertical frame, use manual hoist and cable-stayed to stabilize the two vertical frames, straighten the gate, string foot bolts in all footholes, support the box for one-stage pouring, pay attention to the concrete can not be buried on the gate frame, so that the bottom of the gate frame is three-dimensional pasted on the cement wall, when concrete solidifies, and then again. When adjusting the gate frame, tightening the anchor bolt, and adjusting the gate, if there is a center higher than 0.3 mm, the iron sheet between the gate frame and the concrete wall will be used to eliminate the gap between the gate frame and the concrete wall. 2. When the device is installed, then adjust to the surrounding clearance of 0.3 mm as follows, and then stop the second stage pouring. It is advisable for concrete to bury the gate frame in one half.
