If the quality of a car mainly depends on the quality of the engine, then the quality of a hydraulic freight elevator can only be said to be hydraulic cylinders. Although the oil pumping station is equally important, the production of the current technical oil pumping station has been very stable. The failure of the oil pump station during use is very small. The longest production cylinder in China is 22 meters long, and ordinary small companies cannot produce it. It requires lathes and grinders to process cylinders within 12 meters and 12 meters of shafts at one time, which ordinary small companies can't do. Because the length is too long, there will be errors, which will lead to poor sealing. Generally, hydraulic freight elevators are installed and run-in for 6 months without problems, and basically can be used continuously for more than 3 years.
Installation method for outdoor installation of hydraulic freight elevator:
(The first method) Use the movable scaffolding method to install the freight elevator step by step according to the project progress in the original way. The color steel tiles are also fixed one by one. Compared with the current installation method, the construction period is longer. If the storey height is somewhat higher, the installation Workers may not yet adapt.
(The second method) The freight elevator guide rails are welded on the ground and fixed directly with a crane. The color steel tiles are also sealed on the ground and fixed with a crane. In this way, the cost of two cranes is required to install one, and the color steel tiles need to be added on the ground. The frame can be fixed, but this method can save half of the installation time.
