We all use hydraulic lifts and elevators very frequently in our daily lives. But only some of us are aware of how these elevators function. A wonderful scientific approach works behind the overall functioning of these hydraulic lifts or elevators. Let us understand this science in this blog post.
WHAT IS A HYDRAULIC LIFT?
A hydraulic lift is a heavy-duty elevator built for long-term and frequent use. It has a straightforward working mechanism that involves using hydraulic power for controlling and power generation. They are accommodating in moving people and goods vertically, and this is mainly due to the piston that moves inside the cylinder. An electric motor is installed to pump the oil into the cylinder with immense pressure that moves the piston up to elevate the hydraulic lift.
According to experts in lift modernisation works, hydraulic lifts are ideal for 5 to 6-storey high properties. Earlier hydraulic lifts were powered by water pressure, but modern-day hydraulic elevators and lifts are supported by a piston that moves inside the cylinder due to the pressure generated by oil.
Apart from hydraulic lifts, traction elevators use steel ropes, pulleys, etc., to move up and down.
WHAT ARE THE USES OF HYDRAULIC ELEVATORS?
Hydraulic lifts can be seen in almost every building, and while installing them, two factors have to be considered - the height to reach and the operation speed. As mentioned above, even after lift modernisation works, a hydraulic lift can move up to six storeys high, and the operational speed is also significantly low.
DIFFERENT TYPES OF HYDRAULIC ELEVATORS
HOLED HYDRAULIC LIFTS
To install a holed hydraulic lift, lift modernisation professionals must drill a hole to accommodate the entire cylinder and the piston. This piston will be attached to the elevator cab to push it upwards when the oil is released into the cylinder. The maximum travel distance is 60 feet.
HOLELESS HYDRAULIC LIFTS
No holes are needed to install these hydraulic holeless lifts, and this factor sets them apart from the former. The stipulation is that this version of hydraulic lift can travel a maximum of 40 feet. They can be classified further as telescopic hydraulic lifts, non-telescopic hydraulic lifts, and roped hydraulic lifts.
WHAT COMPONENTS HELP IN THE FUNCTIONING OF A HYDRAULIC LIFT?
Here is a small list of the main components that assist hydraulic lifts.
A hydraulic cylinder enclosing a piston
A reservoir for oil storage
A pump for generating fluid energy
A motor for generating mechanical power
Valves for manipulating fluid flow
