All about Hydraulic Scissor Lifts & Hydraulic Car Lifts
Posted: Sep 25, 2015
Hydraulic Scissor Lifts enable admittance to an elevated work area by raising a framework through a scissor device. The elevation is controlled with the hydraulic cylinders activated by fluid while the retraction is controlled by the slow release of that fluid back in the sump. A sump is a low space that collects undesirable liquids.
The hydraulic scissor lifts and the hydraulic car lifts are broadly used in construction industries, and accordingly, security is a critical factor in designing, manufacturing, and in their operations.
For increase in the loading ability of scissor lift, elements in the lift, like the hydraulic motor, are replaced with more or larger powerful components. Other than increasing the capability of the lift, engineers must ensure that maintenance of safe operating conditions is specified in the given set of instruction manuals with the machine. For doing this, the engineer should determine the rate of descent and ascent and the forces and pressures produced by the hydraulic cylinders.
An elaborate instruction manual can help the industry workers in maintaining safe, secure and optimal working conditions.
The basic application of the hydraulic scissor lifts are in industries like railways, heavy industries, chemical plants, airports, thermal power stations, in heavy maintenance jobs like in industrial shops, air-crafts, manufacturing industries, etc.
The salient features generally include being easy to operate, helps in sturdy construction, lesser maintenance costs, and provide higher service life.
We at Essem Engineers are appreciated as hydraulic car lifts manufacturers and hydraulic scissor lifts manufacturers. Our accurately designed variety in this group is ideal matter handling equipment for moving heavy, medium and light loads easily from ground levels to different floors and unloading and loading of various resources from platforms and vehicles. This easy to operate and low maintenance lift meets the standards of other internationally distinguished products in fields of design, quality and performance.
Hydraulic car lifts operate with the same fundamental concept as any other hydraulic system. When a force is applied to a liquid at one place, pressure is transmitted via the system to apply an effect at some other place. Car lifts make use of hydraulic fluid, which cannot be compressed regardless of how much of pressure is exerted on it. The fluid flows via the hydraulic system and then moves into a cylinder which raises the car from the ground.
A few car lifts make use of an air compressor, whereas the others use electric motors. Other than the utilized power source, the basic ideas are the same. The hydraulic car lift exerts force on hydraulic fluid, which moves into a cylinder in order to raise your car. Trading forces for distance is the common idea in all mechanical systems. In case of a car lift, it means connecting a narrow cylinder to a wide one through hydraulic lines. The oil compressed through the narrow cylinder travels a large distance. When the force is transferred into the wide cylinder, it travels a shorter distance, however with a much greater force.
Car lifts are not only used in service stations and workshops but also in parking lots and showrooms.
Car lifts can be broadly categorized into three categories:
- Two Post Lifts: These help lift the vehicle on two posts therefore the name two post. Apart from these, it also has four arms, two on each post. The vehicle, which is in between the two posts, is locked in its place by these four arms. It is then moved upwards along the posts by hydraulic movement. Once the car has reached the desired height, it is locked in its place so that it does not fall. The amount of weight that the lift can raise depends on the model being used.
- Four Post Lifts: These have four posts. Metal ramps are fixed on the lift to help drive the vehicle on it. Once the car is in place, it is raised by simply pushing a button. The posts have self-locking system that keeps the car in its place. Once the car is locked, it is then lifted up to the required height. These are generally used to raise heavier vehicle that need more support. Some garages use these for creating additional parking space for vehicles – one is raised on the post and the other is parked below it.
3. Specialty Lifts: These are of various types including those with hydraulic scissor lift like function. Some specialty units include low rise car lifts, single post lifts and parking/stacking lifts.
