How can lift, tilt, and rotate tables prevent injury inside the work place?

Lift, tilt, and rotate tables are used for many different applications, but a very common application for a lift, tilt, and rotate table is to help increase ergonomics inside of the work place. These pieces of equipment can help eliminate any unhealthy bending or stretching of the body in the work area to prevent future or long term injures. Ergonomic lift, tilt, and rotate tables help make a more efficient and comfortable work place and can prolong the duration of a employees career.

Why are some Dock Lift applications classified as Custom Lift Tables?

The majority of dock lift manufacturers have a pre-engineered product line selection to cover the majority of all typical dock lift applications hence they are referred to as Dock Lifts. There are a number of applications that a dock lift has to raise higher than a standard dock lift, wider than a standard dock lift, longer than a standard dock lift, stainless steel construction etc. Even though the application requirements are often similar these lifts are outside of many dock lift manufacturers standard product line offering. There are a small number of dock lift manufacturers that also welcome customization to suit a specific application. As this type of equipment is often a “one off” they are processed as custom lift tables, similar to ordering off the menu.

What limitations are there on Self Leveling Lift Tables in a De-Palletizing Application?

Self leveling lift tables are very common in de-palletizing or palletizing applications. When empty self leveling lift tables store in the raised position, in a de-palletizing application a lift truck or a “straddle” lift truck first places the fully loaded pallet on the raised platform. The pallet is then lowered and the weight of the pallet forces the self leveling lift table down into the closed fully lowered position. The top of the loaded pallet is now at the ideal ergonomic operators working height. As the operator de-palletizes (removes product) the self leveling lift table automatically raises keeping the work in the operators best ergonomic position. When de-palletizing completed the process begins again. In this application either a lift truck or a “straddle” lift truck is required, without this equipment being available is the limitation to this product selection.

In a Dock Lift Installation what are protective bollards?

Protective bollards serve the same function as loading dock bumpers. When the truck is backed into position bollards or loading dock bumpers stop the incoming truck movement and protect the loading dock equipment from damage. As many dock lifts are installed ahead of the building foundation steel bollards are typically poured into position to keep the truck from impacting the dock lift. Steel bollards are often 6” – 8” in diameter, typically installed approximately 4’ above grade and 4’-6’ below grade cast in concrete, secure enough to take vehicle low speed impact. The bollards are filled with concrete and often rebar is then inserted. The top of the bollards concrete has a slight crown to assist with water run-off.

Are Low Profile Dock Lifts always ordered with wear plates and retaining cradles?

Not all Low Profile Dock Lifts are ordered with wear plates and retaining cradles but the majority definitely are. Conventional Dock Lifts have a lower steel frame assembly. This steel frame assembly serves a number of functions, 2 of which are the scissor lift leg rollers run back and forth on this steel frame when cycled and the steel frame has provision for lag bolting the dock lift into position during the installation process. To achieve the low profile dock lift feature one of the components deleted is the lower steel frame assembly. In this case the scissor lifts leg rollers would run back and forth on concrete when the dock lift is cycled eventually causing excessive wear to the concrete and leg rollers and a potentially creating a non-level platform. Wear plates are commonly ordered and lag bolted into position at time of installation and the leg rollers run on this steel surface for prolonged operation. Retaining cradles offer 2 benefits, retaining cradles not only lock the dock lift in position when installed but locking in position also increases the end load capacity by 50%. The only practical application for ordering a low profile dock lift without these optional extras is in a portable application.
