Scissor Lifts Tables / Scissor Hoists Information:Smartlift Scissor Lifts Tables and Scissor Hoists combine an extensive range of capacities, features and options to provide the factory and warehouse with lifting and work positioning. The Safetech scissor lifts / scissor table range is designed for durability and includes a large range of safety features that are exclusive to Safetech scissor lifts tables.
Scissor Lift Table Applications
Options
WorkBench OptionsOur unique workbench options have been designed for workers who use their scissor lifts table as a fabrication or assembly bench. .
How do scissor lifts tables work?Scissor Lifts 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 scissor 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
SafetyCare must be taken to prevent entrapment of limbs either in the mechanism or under the scissor lifts 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. Scissor lift tables are often used in conjunction with forklift trucks and they can sometimes damage the table leading to operating failure or injury. LimitationsScissor 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. AlternativesBest BuyingScissor 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 scissor tables are available but expensive. Take care with very cheap tables as they may sacrifice safety standards or durability and performance. |
