Options
- Manual or automatic turntables to rotate the load.
- Tilting decks that present the product to the operator.
- High cycle capacity.
- Safety bars or skirts to protect operators.
- Varied deck construction, stainless steel, chequerplate and more.
- Special frames to capture the load.
- Scissor lift tables can be adapted for use as personnel lifts.
- Low height scissor tables for use with hand pallet trucks.
- Controls can be automated or interlocked with associated equipment
WorkBench Options
Our unique workbench options have been designed for workers who use their Lift Table as a fabrication or assembly bench. .
- On Board power outlets that eliminate trailing electrical cords.
- Multiple hand or foot controls can be supplied to prevent unnecessary movement around the table to change its elevation.
- Welded edge tabs to store tools and welding guns on the table.
- A slide out tray to store tools and plans in.
- Plumbing for air hoses.
How do scissor tables work?
Scissor Lift Tables incorporate a scissor mechanism to hold the platform level but allow it to move vertically.
A hydraulic power unit incorporating electric motor and hydraulic pump supply oil to hydraulic cylinder(s) to elevate the platform.
Most Lift Tables utilise a single acting hydraulic system. This means that the Lift Table raises by oil supplied to the cylinder(s) under pressure from the pump and descends under its own weight when the down valve is opened, allowing oil to be bled back to the tank. This is sometimes known as a power up gravity down system. It also means that lift tables are subject to a slow downward drift over time as oil bleeds back to the tank.
Applications
- Manual palletising or depalletising.
- Loading or unloading of stillages, containers, bins, bags, bricks, tiles.
- Commonly used alongside conveyor, feeding hoppers, extruders, process and production equipment.
Safety
Care must be taken to prevent entrapment of limbs either in the mechanism or under the table's edge. A safety bar is the best protection whilst skirts are also used. The safety bar stops the downward movement of the table upon contact with any obstruction.
Lift tables are often used in conjunction with forklift trucks and they can sometimes damage the table leading to operating failure or injury.
Limitations
Scissor Lifts are active lifting devices and, as such, may be covered by statutory requirements similar to those applying to lifts and cranes.
Lift Tables are not ideally suited to highly accurate platform placement as may be required in automated processes because of the drift that can occur with oil bleeding back to the tank. Alternative lifting mechanisms include screw Lift Tables.
Scissor lifts must be appropriately specified for use in washdown, corrosive or flammable environments or high cycle applications.
Best Buying
Scissor lift prices rise rapidly as extra lift is required - because that requires extra sets of scissors, in high cycle applications or where hand pallet truck only access demands a low height profile table.
Stainless steel tables are available but expensive.
Take care with very cheap tables as they may sacrifice safety standards or durability and performance.
