Pentalift manufactures an extensive line of industrial scissor lifts including ergonomic work positioners, conventional size and capacity lift tables, lift tables for high cycle, high capacity, and high lift applications. In addition, Pentalift also manufactures tilters, rotators, and a wide range of custom positioning equipment. The best investment to extend the lifetime of the equipment and to avoid costly breakdowns and production interruptions are to implement a scheduled maintenance prog... Read More
Scissor lift tables are used in a wide range of applications. These applications include improving ergonomics at the work station, high lifts for work platforms or maintenance procedures, high capacity lift tables, portable lift tables to name some of the more common applications. Lift tables, lift tables with rotating tops and lift tables with tilting tops are proven to be an ergonomic solution to minimize or eliminate repetitive operator bending, stretching or reaching. In addition to the e... Read More
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 cle...

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 lowering if any obstruction (operator’s foot, debris etc.) contacts the suspended 4 sided perimeter bar the lowering stops immediately. Second the ro... Read More
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 St... Read More
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 switches, one per corner. When the down button is activated the electrical signal t... Read More
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 trave... Read More
Most lift table manufacturers recommend a maximum hydraulic hose length for remote/external power units that should not be exceeded for satisfactory performance.  The issue is not raising the lift table; a pressurized hydraulic hose of almost any practical length will raise the lift table, the issue is lowering the lift table. If the lift table is lowered with weight on the platform the weight will assist in pushing the hydraulic oil back through the hydraulic hose to the reservoir. If the lift... Read More
There is no definitive answer to that question but there are reasonable expectations. A lift table that is cycled up to 8 times per hour in a single 8 hour shift and a 5 day work week should last 20+ years if properly inspected and maintained. It is very important that lift tables be designed and equipped to suit the specific requirements of the application. For example a lift table operating in a wash down application or an outdoor application should have an upgraded finish coat such as epoxy p... Read More
Although the majority of lift table applications have a single control station it is not uncommon to have multiple control stations. A typical example would be a lift table installation that services 2 different floor levels. One set of controls is located at the lower level and the secondary set of controls is located at the upper level. The lift table can now easily be called from one location to the other without the use of stairs. If the lift table can be operated from 2 locations both of th... Read More
