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
The first step when considering converting to hydraulic operation is to investigate if the dock leveler is structurally sound. In its simplest form a dock leveler is a temporary structural bridge between the building floor and the truck to be loaded. A qualified loading dock service technician should first perform a complete front to back structural inspection of the dock levelers primary components. During the inspection the technician should check the deck, beam and headboard weldments, the li... 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
The most significant benefit of converting a mechanical dock leveler to hydraulic is the safety and ease of single push button operation at the loading dock area. Converting to hydraulic eliminates the need to repetitively bend and pull the release chain and then walk the dock leveler downward into position on the truck. When successfully converted to hydraulic operation it’s now as easy as pushing a button. Any brand of mechanical dock leveler will require an ongoing maintenance program that ... 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 manifold that monitors the returning oil flow rate from a bank of multiple lift cylinders. Velocity fus... Read More
The overall lifting capacity is the most common and most referred to rating on a lift table. The overall rating is based on an evenly distributed load and these ratings typically range from 500 lbs to 20,000 lbs. Lift tables that are used to accommodate a rolling load such as a pallet truck or rolls of paper, coils of steel etc. have 2 additional capacity ratings; single axle end load and single axle side load ratings. The end and side load capacity ratings only apply when the lift table is in a... Read More
Although it is not very common you can use a lift truck on a dock lift if the dock lift is properly sized, rated and equipped. Some of the factors to first consider. The dock lift platform size should accommodate the overall length of the lift truck with the longest load that the lift truck will be carrying. The width of the dock lift should be sized to allow the lift truck operator to exit the lift truck and move around freely on the platform. When selecting the dock lift capacity consider a co...

Working with bins of bulk product can often be challenging for the machine operator. The challenges arise because of the repetitive bending and stretching required reaching down into the bin to load or unload components. In this application consider if the product bin is first loaded onto an industrial hydraulic tilter. Under operator control the bin can now be tilted into the most ergonomically correct and comfortable position for the operator to retrieve or place the components in the bin. Til... Read More
When a lift table lowers into a recessed pit there is often the challenge of addressing a potential pinch point. A lift table with straight 90 degree vertical toe guards on the platform sides can create a pinch point as the platform lowers into the pit. The two most common lift table options to minimize the risk of a pinch point as the platform lowers are tapered toe guards or electric toe sensors. Tapered toe guards are tapered inward 30 degrees on all 4 sides of the platform sides. Changing th... Read More
The majority of lift tables receive a sprayed on finish coat, this sprayed on finish coat often includes products such as enamel paint, epoxy paint or even cold spray galvanizing. None of these finishes can compare to the high performance coating of hot dip galvanizing. During the hot dip galvanizing process the components are first dipped into a tank of a cleaning acid solution, removed and then dipped into a separate tank containing the molten galvanizing solution. As opposed to any spray on f... Read More
