What’s new in Hydraulic Lift Tables?

The most significant change is not actually in the lift table design but the new and innovative ways that lift tables are being used. In this competitive environment many companies are constantly looking for ways to improve efficiencies and save money. Lift table manufacturers that provide custom designed lift and positioning equipment are seeing more and more innovative inquiries from customers as they look for ways to streamline their processes. Even long term tried and proven processes are now being looked at with an eye towards how we can make this process even more efficient. The customer knows their end goal and they are calling on custom lift table manufacturers for assistance in applying lift, tilt and rotation practises to many new applications.

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.

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

Self leveling lift tables are very common in palletizing or de-palletizing applications. When empty self leveling lift tables store in the raised position, in a palletizing application first an empty pallet is placed on the platform. As product is moved onto the pallet the increased weight automatically lowers the lift table keeping the operators work height at an ergonomically correct position. When the lift table is fully lowered the pallet is full. A lift truck is then required to engage the pallet and lift it above and clear of the self leveling platform, the self leveler will raise with the pallet to the empty, raised stored position. 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.

What is Pentalift LTNI?

LTNI stands for “Lift and Tilt Non-Intrusive”. Components are often shipped in bins and during the loading and unloading process a combination of a lift table and a tilter positions the bin in the most ergonomically correct position for the operator. Conventional tilters force the operator to step back when the bin is tilted towards them. In many applications where there are no space restrictions this model of lift and tilt works well. The Pentalift LTNI is a combination of a lift and tilt that does not force the operator to step backwards through its unique design. This model of lift and tilt is ideally suited for working in tight congested areas where space is premium.

Why do higher capacity lift tables require a higher HP power unit?

Technically they don’t require a higher HP power unit to operate but almost every time they are specified. A lift table power unit consists of 5 primary components, electric motor, hydraulic pump, hydraulic valve, oil reservoir and a control station. As lift tables increase in lifting capacity more cylinders are used in the structural design to lift the load. Additional lift cylinders increase the volume of hydraulic oil required to operate the lift table. To provide a suitable lift speed a larger volume hydraulic pump is required to increase the oil flow rate to the lift cylinders. To drive the larger volume pump a higher HP electric motor is required. For example a 20,000 lb capacity lift table with a 3 HP power unit takes approximately 121 seconds to lift 59”. The same lift table equipped with a 10 HP power unit takes approximately 25 seconds to lift 59”. Higher HP power units drive higher volume pumps which increases lift speed.
