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
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...

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
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
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...

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
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 table is lowere... 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
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 the control statio... Read More
If this option is ordered the hydraulic velocity fuse is installed in the return line of the lift table’s hydraulic circuit. As the lift table starts to lower the hydraulic oil flows out of the lift cylinder(s) and through the velocity fuse to the power unit reservoir. Depending on the model of lift table the velocity fuse is installed directly on the base of the lift cylinder or in a common man... Read More
