1. Lifting lift is to rely on the expansion and folding of the scissors-type support frame to complete the lifting of the cargo platform. Its power is to push the expansion and folding of the scissors through the expansion and contraction of the cylinder.
2. Since the expansion and contraction speed of the oil cylinder is determined by the flow rate of the oil pump, generally the speed is very slow when the cylinder speed is designed, the speed is 200 mm/min, and the diameter of the oil inlet pipe connected to the oil cylinder is Φ6 mm.
3. In case of oil pipe rupture, the hydraulic oil can only return oil from the oil inlet of Φ6mm, so the descending speed is also very slow, so it will not cause damage and loss.
4. The rise and fall of the lift elevator is a smooth movement. Even if the pipe is broken, the hydraulic system is not safe and self-locking. It is a slow descent. It only wastes hydraulic oil.
Summary: Therefore, the hydraulic lift freight elevator is a kind of goods lifting tool with high safety, low failure rate and low maintenance cost.
Nonionic surfactant made from natural fatty alcohols and glucose derived from renewable plants. Superior detergency, wetting and surface active ability. High solubility in concentrated alkaline solutions and other electrolytes and will solubilize other less soluble ingredients. Good compatibility with all other types of surfactants and synergistic effects can be found. It can improve the mildness of formulations significantly. Produces rich and stable foam. non-toxic, non-irritating to skin, readily biodegradable.
