Characteristics of Tandem Lift Tables.

A Tandem Lift Table is a table that is used for an application in which the platform’s length needs to be much longer than the platform’s width. Tandem Lift Tables are generally used to assist lengthy and narrow applications such as long pieces of wood, 2x4’s or hydro poles. To support the oversized load, there are 2 sets of scissor legs under the table’s platform to accommodate the load it is lifting. Tandem lift tables cost more than standard lift tables but are the perfect piece of equipment for certain applications.

What Are The Different Operating Choices For Lift Tables?

There are 3 different operating types of lift tables. They are hydraulic, pneumatic and self leveling. All 3 styles are different but have their benefits, depending on what the application is. Hydraulic lift tables offer the widest range of features and customization regarding platform size, capacity, vertical travel, and safety features. Pneumatic lift tables are offered in an air bag design which is limited to 24” of travel. The air bag lift tables may be limited but if an airline is the only power source available to run the lift table, an air motor running a hydraulic system is available. Pneumatic lift tables are commonly used in wash down or areas where electrical sparking can cause a concern. Self leveling lift tables are mostly used for ergonomic applications. Self leveling lift tables require no power at all but do require a fork truck in order to load or unload the full pallet.

When Do You Choose A Dock Lift Instead Of A Dock Leveler?

Dock lifts are generally used if you don’t have a conventional 4 foot high loading dock area. A dock lift would be used to get product from a truck to ground level or vice versa. In multiple dock positions, something that is becoming more common is the use of a dock lift. While dock levelers will handle the conventional trucks, in addition to conventional trucks a dock lift can accommodate any incoming truck bed height (FedEx, UPS, etc.). Dock lifts can also be used to store property maintenance equipment in the offseason. Common applications for a dock lift are institutions, retail outlets, universities, hospitals, etc. If the decision is to go with a dock lift, you can select from a pit installed model or a surface installed (no pit required). Often the application dictates the most appropriate product to select.

Factors to Consider When Deciding Between a Hydraulic Dock Leveler or a Mechanical Dock Leveler

Choosing between a hydraulic dock leveler and mechanical dock leveler depends on what is most important to the user. Mechanical dock levelers cost less than hydraulic dock levelers, but mechanical dock levelers do require periodic (2 times a year) adjustable maintenance throughout use of the equipment. Hydraulic levelers can handle higher load capacities and also operate more easily than mechanical dock levelers, due to a manual push button that operates the power unit. While hydraulic dock levelers do require a power source, mechanical dock levelers do not require any sort of electric power due to its spring activation. Both hydraulic dock levelers and mechanical dock levelers should be lubricated and inspected regularly to prolong safe operation.
