The main types of jacks
2025/11/11
Mechanical jack
Principle: Using spiral or gear transmission, the force is amplified by manually rotating the handle.
Features: Simple structure, low cost, no need for external power, but slow improvement speed and high labor intensity.
Applicable scenarios: light vehicle maintenance, household emergency, etc.
hydraulic jack
Principle: Using Pascal's law, pressure is transmitted through hydraulic oil to achieve high load lifting.
Features: High lifting force, easy operation, high stability, but requires regular maintenance of the hydraulic system.
Subtype:
Split hydraulic jack: The pump and lifting part are separated, suitable for remote operation.
Integrated hydraulic jack: integrating pump and lifting device, with strong portability.
Applicable scenarios: heavy equipment installation, bridge construction, automobile rescue, etc.
pneumatic jack
Principle: Using compressed air to drive piston movement and achieve lifting.
Features: Fast speed, clean and environmentally friendly, but requires gas source support and high cost.
Applicable scenarios: automated production lines, dust-free workshops, etc.
Electric jack
Principle: The motor drives the gear or hydraulic pump to achieve automated lifting.
Features: Easy to operate, remotely controllable, but dependent on power supply.
Applicable scenarios: large-scale equipment maintenance, stage construction, etc.
