Product Usage
rack and pinion mechanical jack is a safe, practical and convenient lifting,Its biggest advantage is that it overcomes the shortcomings of jacking weight falling caused by the hydraulic leakage of the hydraulic jack, it maintain a long stay in the support position, so particularly suitable for upgrading of the heavy long position after the occasion demands. Some frequently used in the following situations:
1. Mechanical assembly and repair of vehicles from the top of the machine when used, vehicles and equipment used to from the top of prefabricated construction, etc..
2. Railway sector maintenance when used in railway tracks from the top.
3. Mines, tunnels, bridges, concrete poured in the pit prop support.
4. Loading and unloading will be prostrate, lifting a lower position of the items before the pre-top.
Screw Jack Benefits
Self-locking feature: This is undoubtedly their most significant advantage. Once the rotational force on the screw is removed, the screw will remain stationary and motionless, regardless of the load it is carrying. This inherent self-locking feature makes them extremely safe, as they will not "backdrive" or withstand a load drop without active input. This eliminates the need for external braking mechanisms, which improves safety and stability.
Precise positioning and control: Screw jacks allow for very fine and precise adjustments during lifting or positioning. The linear motion is proportional to the rotational input, providing superior control for tasks that require precise height or position.
High load capacity: Although screw jacks are generally compact, they are designed to withstand large static and dynamic loads ranging from a few kilograms to hundreds of tons.
Mechanical advantage: They use the mechanical advantage of the screw thread to lift very heavy loads with relatively small input forces (torque). This makes heavy lifting a breeze.
Reliability and Durability: Made of sturdy materials (usually high-quality steel), screw jacks are known for their durability, long service life, and reliable performance, even in harsh industrial environments.
Versatility: They can be operated manually, electrically (motor), or even hydraulically/pneumatically. They can lift, lower, push, pull, tilt, or roll loads, and can be used in a variety of orientations (upright, inverted, horizontal).
No fluid leaks or contamination: Unlike hydraulic jacks, screw jacks do not use hydraulic oil, eliminating the risk of leaks, contamination, and associated maintenance. This makes them suitable for clean environments such as food processing or medical applications.
Synchronization: Multiple screw jacks can be easily synchronized to simultaneously lift or position large, uneven, or complex loads, ensuring smooth, even movement.
Cost-effective solution: In many applications, screw jacks are a cost-effective solution both in terms of initial purchase and long-term maintenance compared to more complex hydraulic or pneumatic systems.
Applications of Screw Lifts
1. Industrial and Manufacturing
Machine Tools: For precise height adjustment of workbenches, jigs, fixtures and tools in CNC machines, lathes and milling machines.
Assembly Lines: For lifting, lowering and positioning parts during assembly, especially for heavy machinery.
Material Handling: For conveyor systems, ergonomic lifts and palletizing equipment for transfer or lifting sections.
Presses: For use as lifting or actuators in various mechanical presses.
Welding Positioners: For adjusting the height and angle of welded parts.
Furnaces and Ovens: For adjusting the height of heating elements or opening/closing oven doors.
2. Automotive and Transportation
Vehicle Lifts: For lifting cars, trucks and other vehicles for maintenance and repair in garages and workshops.
Railway Maintenance: For lifting rails or train cars for repair or inspection.
Aircraft Maintenance: For assembly platforms and ground support equipment for positioning and repairing aircraft parts (e.g. engines, fuselage sections).
Vehicle Ramps: For adjusting the height of ramps for loading and unloading.
3. Construction and Civil Engineering
Scaffolding: Adjustable screw jacks are used to level scaffolding structures on uneven ground, ensuring a stable and safe working platform.
Structural Support: For temporarily or permanently supporting, lifting and leveling heavy structural members such as beams, columns and concrete slabs during construction or renovation.
House Lifting and Leveling: For lifting entire houses or parts of buildings for foundation repairs or relocation.
Bridge Maintenance: For lifting bridge sections for inspection or repair.
4. Specialized High Precision Applications
Solar Trackers: Adjust the angle of large solar panels to maximize sunlight throughout the day.
Satellite Antennas: Precisely position large satellite antennas for optimal signal reception.
Stage and Orchestral Platforms: Lift and lower stage sections in theaters and concert halls for dynamic performances.
Medical equipment: adjustable beds, patient transporters, and some diagnostic equipment that requires precise positioning.
Guardrail systems: lifting safety guardrails or bollards.
