What are Self Leveling Lift Tables?
Self-leveling lift tables are weight sensitive and are most commonly used in a palletizing or de-palletizing application. Self-leveling lift table platforms are typically 48” x 48” and are equipped with a rotating top. In a palletizing application self-leveling lift tables are at rest in the raised position with an empty pallet on the lift table platform.
The lift table is held in the raised position by extended compression springs. As weight is added to the pallet the springs compress and the platform gradually lowers keeping the operators work height at an ergonomically correct positi... Read More

What are the portability options available for lift tables?
Semi portable, fully portable and power driven are the 3 most common portability options available for lift tables. Semi portable models are equipped with 2 load rollers and bearings on one end of the lift table frame and a removable 2 wheeled dolly handle at the other end of the frame. Engaging the dolly handle raises that end of the frame slightly up off the floor transferring the weight to the rollers located on the opposite end of the frame providing portability. The lift table... Read More

Can hydraulic lift tables be ordered with synchronized operation?
Yes multiple lift tables can be ordered with synchronized operation. The question to first address is what level of synchronization is actually required and is the weight of the load on each lift table the same? Basic synchronization can often be accomplished through the use of a geared hydraulic flow divider. This system provides fairly consistent accuracy and repeatability however there may be some minor height variations during the operating cycle. With this design when all of the lift tables are fully lowered or fully raised the synchronization automatically resets. The next level of syn... Read More

Lift Table Remote Power Unit Placement Guidelines?
ProSeries remote power units are generally installed right on the floor within close proximity of the lift table. Remote power units are supplied with 10’ of hydraulic hose as standard however longer hydraulic hose lengths are available; depending on the model up to 35’ of hydraulic hose can be ordered. An optional wall mounting bracket is available to install the power unit up off the floor and out of harm’s way. It is recommended to install this option with a minimum of 6’ of under clearance to minimize ... Read More

Why are lift table scissor leg sets often “stacked”on top of each other?
To understand why the scissor leg sets are stacked on top of each other first keep inmind thatthe longer the scissor leg assembly the higher the lift will go. For example a 4’ long leg set will provide approximately 3’ of lift, a 6’ long leg set will provide approximately 4’ of lift, an 8’ long leg set will provide approximately 5’ of lift etc. Following this ratio/guideline a lift table application that requires 8’ of lift would typically require a 12’ long leg set. Many applications do not have the 12’ of floor space available to install a lift table that will lift a load 8... Read More

Safety considerations when installing a lift table with a rotating top in a pit.
The main concern is operator safety as it relates to eliminating potential pinch/shear/crush points when the lift table platform and rotating top lowers into the pit. First the lift table is equipped with . Electric toes sensors are an interlocked 4 sided bar assembly that is suspended under the lower 4 sided edge of the lift table platform. When loweri...

What is a Sure Stop Valve on a lift table?
On an electro-hydraulic lift table the lift motor is mechanically coupled to the hydraulic pump. When the lift motor is activated the hydraulic system pumps the hydraulic oil to the lift cylinders and the lift table rises. When the lift motor is shut off by there is a slight overrun “freewheel” effect, the pump continues to pump oil for a split second and the lift table rises slightly. If precise positioning is required a Sure Stop Valve is added to the hydraulic circuit. At rest the Sure Stop Valve is normally close... Read More

What are the options for Dock Lift guard rails?
As standard dock lifts are supplied with removable guard rails. At the time of manufacture the guard rails are bolted to a threaded plate that is welded to the dock lift platform. These guard rails are now removable however they require hand tools to first remove the locking bolts, 4 locking bolts per guard rail. Based on the amount of work required and the time involved removing this style of guard rail is not a common practice to do repetitively. Another option... Read More

What are lift table electric toe sensors and how do they work?
Electric toe sensors are most commonly used on lift tables that are installed in a preformed recessed pit. In a recessed pit installation there is the potential for introducing a shear hazard as the platform lowers into the pit. Electric toe sensors are an interlocked 4 sided bar assembly that is suspended under the lower edge of the lift table platform. The suspended perimeter bar assembly interacts with 4 limit switche...

Can you load and unload dock lifts from the side?
Yes you can. With the dock lift in the lowered position there is no issue. However if the dock lift is to be loaded or unloaded from the side in the raised position the dock lift capacity rating must be carefully selected to avoid platform deflection and premature wear. Dock lifts are generally loaded and unloaded from the ends. The weight moves on and off the dock lift platform travelling with the length of the scissor legs. When dock lifts are loaded and unloaded from the side the weight travels across the width of the scissor legs. Travelling across ... Read More
