Lift Parameter Encyclopedia: Selection Guide, Working Principle, Specification Reference, Operation Tips and Performance Analysis
This professional parameter encyclopedia for industrial lifts systematically sorts out core working principles, key selection dimensions, standard technical specifications, standardized operation methods and performance characteristics of different types of lifts, with a detailed parameter compariso
This parameter encyclopedia is compiled for industrial users to fully understand the core information of lifts, covering all key reference points required for pre-purchase selection, in-use operation and post-purchase maintenance.
1. Working Principle of Industrial Lifts
Industrial lifts are divided into multiple categories according to power modes, and their core working principles are as follows:
Hydraulic Lift: Driven by a hydraulic power unit, the hydraulic oil is pressurized to drive the piston to move linearly, and the scissor arm or direct lifting structure drives the platform to rise and fall. It has the characteristics of stable transmission and strong load capacity.
Traction Lift: Driven by a traction machine, the steel wire rope drives the car platform to move up and down through the traction wheel, with high lifting height and fast operation speed, mostly used for high-rise building material transportation and passenger-cargo dual-purpose scenes.
Screw Lift: The motor drives the screw to rotate, and the nut sleeve connected to the lifting platform moves linearly along the screw to realize lifting, with high positioning accuracy, no falling risk and long service life.
2. Key Selection Criteria for Lifts
When selecting lifts, users need to judge according to the following core dimensions to ensure that the equipment matches the actual use requirements:
- Load Demand: Confirm the maximum weight of goods or personnel carried in a single operation, and reserve a 10-15% safety margin for the rated load of the selected equipment.
- Lifting Height: Calculate the actual maximum height required for operation, and confirm whether the equipment can meet the height demand under the condition of meeting the floor height limit of the use site.
- Use Scenario: Choose fixed lifts for fixed loading and unloading docks, mobile lifts for temporary outdoor operation scenes, and explosion-proof lifts for flammable and explosive special scenes.
- Safety Configuration: According to operation requirements, select matching safety configurations such as overload protection, limit switch, emergency descent device, and anti-fall safety lock.
- Power Supply Conditions: Select 220V, 380V AC power supply or diesel powered equipment according to the power supply configuration of the use site.
3. Standard Technical Specifications and Parameter Comparison Table
The following are the standard parameter configurations of common mainstream lift models on the market for user reference:
| Model | Rated Load (kg) | Max Lifting Height (m) | Lifting Speed (m/s) | Platform Size (mm) | Rated Power (kW) | Whole Machine Weight (kg) | Applicable Temperature Range (℃) |
|---|---|---|---|---|---|---|---|
| SJY0.3-3 | 300 | 3 | 0.08 | 1300*800 | 1.5 | 350 | -20~+45 |
| SJY0.5-6 | 500 | 6 | 0.07 | 1600*1000 | 2.2 | 680 | -20~+45 |
| SJY1-10 | 1000 | 10 | 0.06 | 2000*1200 | 4 | 1500 | -20~+45 |
| SJG2-4 | 2000 | 4 | 0.05 | 2500*1500 | 3 | 1200 | -25~+50 |
| SC200/200 | 2000*2 | 100 | 0.6 | 3000*1500*2200 | 2*11 | 14000 | -30~+50 |
Note: The above parameters are for reference only, and non-standard customized parameters can be adjusted according to user needs.
4. Standardized Operation and Use Guide
Standardized operation can effectively extend the service life of lifts and avoid safety risks, and the core operation process is as follows:
- Pre-use Inspection: Before starting the equipment, check whether the power supply is stable, whether the hydraulic oil level is normal, whether the safety protection device is in good condition, and carry out 1-2 no-load test operations before loading operation.
- Operation Process: Overload is strictly prohibited, and violent shaking operation on the platform is strictly prohibited. When encountering an emergency during operation, press the emergency stop button immediately, and it is forbidden to press the lifting button forcibly when the equipment fails.
- Post-use Maintenance: After the operation is completed, lower the platform to the lowest position, cut off the power supply, clean the sundries on the platform, and carry out regular maintenance such as replacing hydraulic oil and tightening fasteners according to the equipment manual.
5. Performance Advantages and Applicable Scenario Introduction
Different types of lifts have their own adaptive characteristics, and the specific performance advantages are as follows:
- Hydraulic Scissor Lift: It has the advantages of large load capacity, stable operation, simple maintenance and low cost, and is suitable for cargo transfer between factory floors, warehouse loading and unloading, and outdoor high-altitude maintenance operations with a height of less than 18m.
- Traction Lift: It has the advantages of high lifting height, fast speed, low energy consumption and low noise, and is suitable for high-altitude material transportation and passenger-cargo dual-purpose scenes in high-rise buildings, construction sites, etc.
- Screw Lift: It has the advantages of high positioning accuracy, no falling risk, long service life and no oil leakage, and is suitable for precision equipment installation, food workshops, clean rooms and other scenes with high environmental requirements.
When selecting models, users can combine the above parameter reference and scenario adaptation suggestions, and contact suppliers for customized parameter adjustment according to actual needs.
