How to choose electric lift jack tools in outdoor humid environments
✅ List of core selection elements for electric screw lift and electric jack
| Selection dimension | Recommended Configuration | Technical Basis and Explanation |
| Protection level | IP65 | Completely dust-proof and water-resistant (compliant with JB/T 9001-2015 outdoor standard), preventing water vapor from entering the worm gear box and causing lubrication failure |
| Structural protection | Telescopic protective cover+anti-corrosion coating | The telescopic cover can automatically close with the screw up and down, blocking rainwater and coolant splashing; Spray epoxy resin anti-corrosion coating on the surface of worm and screw, with salt spray resistance of ≥ 500h |
| Worm gear material | Hardened steel tooth surface (HRC58-62) | Worm gear material Hardened steel tooth surface (HRC58-62) Compared to soft tooth surfaces, the ability to resist moisture corrosion is increased by 40%, avoiding tooth surface pitting and plastic deformation |
| Power system | Variable frequency three-phase asynchronous motor+electromagnetic brake | The frequency converter can smoothly start and stop, reducing impact loads; The brake ensures power-off self-locking to prevent slipping due to lubrication film failure in humid environments |
| Installation method | Double screw symmetrical installation+middle support | Enhance the ability to resist lateral forces and avoid bending and deformation of the screw due to uneven foundations or wind loads |
| Drive power supply | Optional 24V/48V DC battery driven type | Suitable for outdoor mobile platforms without fixed power sources (such as ports and logistics yards), to avoid the risk of cable moisture and short circuit |
| Control method | PLC integration+waterproof operation box (IP65) | The control cabinet adopts a sealing rubber ring and anti condensation design, and the buttons are sealed with rubber film to prevent water vapor from entering the circuit board |
📊 Recommended Model and Scene Matching Table (for outdoor humid environments)
| Model | rated load | Recommended Configuration | Typical application scenarios |
| SWL10 (IP65 version) | 10t | Hard tooth surface+telescopic cover+anti-corrosion coating+variable frequency motor+electromagnetic brake | Steel coil jacking in steel plants, outdoor lifting of bridge formwork, and leveling of port containers |
| SWL15 (IP65 version) | 15t | Double screw symmetrical+middle support+battery drive option+PLC waterproof control | Outdoor transportation of new energy battery lines and outdoor positioning of large molds |
| SWL50 (IP65+battery version) | 50t | Fully enclosed structure+waterproof junction box+48V lead-acid battery pack | Large scale warehousing and logistics platform, outdoor yard heavy-duty lifting and lowering |
