Screw elevatorIt is a basic lifting component that complies with the JB/T8809-2010 (formerly JB/T8809-1998, JB/ZQ4391-86) standard. The load-bearing capacity is 2.5-120T. The screw lift is suitable for low-speed and low-frequency applications, and its main components are precision trapezoidal screw pairs and high-precision worm gear pairs. It has the advantages of compact structure, small volume, light weight, wide power source, low noise, easy installation, flexible use, multiple functions, multiple supporting forms, high reliability, and long service life.

Screw elevatorThe working environment

1. The maximum allowable power is a parameter under the conditions of an ambient temperature of 20 ℃ and a working duration of 20% per hour.

2. The overall efficiency is a parameter under grease lubrication conditions.

3. The allowable torque, power, and speed for increasing different loads are different, and the maximum power for different starting durations is also different.

4. For elevators with dual guide sleeves, the screw is allowed to withstand a certain amount of lateral force in addition to axial force.

5. The extension of the shaft is allowed to withstand a certain radial force and allows for the installation of gears, sprockets, or pulleys.
