Hydraulic freight elevator is a vertical elevator equipment that is powered by oil pressure and uses steel wire ropes and pulley systems to lift and lower goods. Its main features include:

1. Easy to operate: equipped with control system and emergency system; It has the characteristics of smooth operation, high load capacity, and is equipped with a multifunctional machine room free design compatible with passenger elevators. It can be freely equipped with external door machines and other accessories for use in various occasions.

2. Economical and practical: Gas stations only require electricity without water, which has great advantages in environments where resources are increasingly depleted; The cost is relatively low and the maintenance cost is also relatively low. And it can be configured and selected according to different needs to meet different carrying and usage requirements. 3. Green and environmentally friendly: No need for a main engine room or shaft, saving a lot of building floor space, expanding fire exits, and further improving the construction environment, etc. 4. The installation is convenient, flexible, and has a long service life. The high-strength alloy shell adopts the new technology of "four point suspension", which eliminates a lot of after-sales maintenance links for the automatic fuel pump on the top of the rail chain crane chassis (extending the service life of many components). The strong tensile resistance and sealing material guarantee have increased the shelf life of the product from two years of original factory warranty to one year of free replacement of parts or material fee service at local offices. Overall, it has the advantages of high safety performance, speed, and high return on investment, and is suitable for various places such as shopping malls and warehouses. The above information is for reference only. Specific applications need to be judged based on actual situations to determine their applicability.
