Why would you use a scissor lift?
Scissor lifts are work platforms used to safely move workers vertically and to different locations in a variety of industries including construction, retail, entertainment and manufacturing.
What is a scissor lift mechanism?
Introduction. Scissor lifts, as depicted in figure 1, are a type of mechanism that allows for vertical displacement of some load, through the use of linked, folding supports, in a crisscross “X” pattern, referred to as a pantograph (or, simply, a scissor mechanism).
How does a hydraulic scissor lift work?
Hydraulic Power in Scissor Lifts In the simplest terms, hydraulic scissor lifts operate by pushing liquid from one area to another. More specifically, the motor or air compressor forces hydraulic fluid into the associated cylinder, which causes that cylinder to be pushed outwards.
What is hydraulic scissor lift?
The hydraulic scissor lift is the most common type of industrial lift found. It makes use of a motor or power source with pressurized hydraulics in order to lift loads. The hydraulic cylinder enables the scissor lift to go higher or lower. Scissor lifts usually have one to three cylinders present.
Do I need a harness in a scissor lift?
If you’re using a vertical or scissor lift, however, it’s not always necessary to use fall protection equipment – like a harness – unless called for by exceptional circumstances.
Can you drive a scissor lift while elevated?
Elevated drive speed for Aerial work platforms: It goes without saying that you can drive Aerial Work Platforms (AWPs) forward and reverse, like just about any vehicle. When the boom or scissor lift is elevated, the machine is less stable, and driving at an excessive speed could cause the AWP to tip over.
How are scissor lifts measured?
Generally, the first two numbers are the platform height, whereas the last two numbers are the width of the machine. Take the Genie GS 1930 scissor lift, for example, it has a 19-foot height and is 30 inches wide. However, some brands such as Skyjack reverse the numbers and put the width first and the height second.
What sizes do scissor lifts come in?
Scissor lifts can extend as high up as 60 ft., or about one-third the height of the tallest aerial lift. Most working heights range from 20-40 ft. Scissor lifts have less reach power than boom lifts but can hold more weight. Many scissor lifts have an unrestricted weight limit of 1,000 lbs.
Is a scissor lift a hydraulic system?
The Hydraulic scissor lift mechanism relies on cylinders filled with a reservoir of hydraulic fluid. This fluid maintains pressure on the lift and holds the working platform at the desired height when the unit is extended.
Are scissor lifts Electric?
Electric. Electric scissor lifts are another popular aerial platform machine. An alternative to burning fuel, electric scissor lifts feature a silent, powered drive mechanism. These machines are also less bulky than their diesel counterparts, making them optimal in smaller spaces.
How do you power a scissor lift?
Scissor lifts use a key to start the lift and turn it off. Take your key and insert it into the ignition next to the large red button on the control panel. Turn the key to the right to turn the lift on. The control panel is the small box with the joystick inside of the lift.
