How to choose a motor screw jack?
As important equipment in industrial production, the selection of electric screw elevators/electric jacks directly affects their efficiency and safety. How to quickly find the model that suits oneself? Today, let's share 5 key purchasing tips
1. Clearly define the usage scenarios and load requirements
Firstly, it is necessary to determine the operating environment of the elevator: indoor or outdoor? Do
you need special protection such as explosion-proof and waterproof? Secondly, based on the load
calculation: the maximum load-bearing capacity of a single unit needs to meet the actual working
conditions to avoid overloading operation. For example, small devices can choose loads below 500kg,
while heavy machinery requires models above 1000kg.
2. Pay attention to running speed and travel parameters
Different industries have different requirements for lifting speed: warehousing and logistics commonly
use medium speeds of 0.1-0.3m/s, while precision instruments require slow speeds below 0.05m/s. In
terms of travel, it is necessary to measure the vertical height of the installation space, and it is
recommended to reserve 10-20% margin to prevent insufficient travel from affecting operation.
3. Investigate the drive motor and control system
The motor is the core power source: copper wire motors are preferred for their good heat dissipation
performance and long lifespan. It is recommended to choose a model with overload protection and
limit switch for the control system to avoid equipment loss of control due to malfunction. Some high-end
models also support intelligent programming control, which can achieve remote operation or timed lifting.
4. Emphasize installation methods and maintenance convenience
Common installation forms include fixed, mobile, suspended, etc., which need to be selected according
to the site layout. When maintaining, consider whether it supports quick disassembly and whether spare
parts are easy to purchase. For example, the trapezoidal screw drive structure is simple and suitable for
daily maintenance; Ball screws have high precision but require regular lubrication.
