When properly specified a declined dock area can be sealed just as effective as if it was a level approach. First you determine the percentage of decline at the loading dock area, this is done by calculating the amount of rise over 50’ from the front of the dock area. For example let’s say the percentage of decline is 4 percent. For a proper seal start with 4”-6” of dock seal projection beyond the face of the dock bumper at the bottom of the side pads. Now deduct 1” of projection at th... Read More
The majority of vehicle restraints are fastened directly to the face of the foundation wall. In some cases the foundation wall will not withstand the forces to hold the vehicle restraint in position such as a concrete block wall or a brick wall. In new construction with the concrete pre cast (tilt up) wall the contractor often specifies that nothing is to be bolted to the face of the wall. To address a vehicle restraint installation that cannot be attached to the foundation wall Pentalift has de... Read More
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 la... Read More
Flaps or as they are commonly referred to as “wear pleats” extend the life of a compression style dock seal. With the truck backed into position there should be 4” -6” of dock seal foam compression, this amount of compression provides the best seal. As the truck is loaded or unloaded it is natural for the truck bed to move up and down. The trucks up and down movement has an abrasive effect on the front of the dock seal side pads, the wear pleats provide an outer layer of protection that ... Read More
Although there is a common perception that accordion bellows are a safety device they are not promoted as such. The primary purpose of lift table accordion bellows is to prevent debris from getting under the lift table and interfering with the leg rollers, power unit etc. Many companies mandate that all lift tables within their facility be equipped with accordion bellows to prevent debris from getting under the platform and the yellow accordion bellows also serve as a highly visible signal that ...

Compression, with foam pad dock seals the amount of compression is very important. Too little compression results in not enough of a sealing factor, too much compression puts excess pressure on the building wall and causes premature failure of the dock seal. It’s very easy to calculate the correct amount of dock seal compression; measure from the wall the dock seal will be installed on to the face of the dock bumper and add 4”– 6”. 4”-6” of dock seal projection beyond the face of the...

When selecting a dock lift, you want to make sure you find the most appropriate one for your application. The 5 main things to look for when choosing a dock lift would be whether the equipment is going to be floor mounted or pit installed, platform dimensions, what the lifting and roll over capacities will be, bridge lengths and what voltage will be offered to the dock lift at the place of installation. The manufacturer needs to know whether the equipment is going to be pit installed or placed o... Read More
Lift tables that are placed in a pit require different features than a lift table that is lagged to the floor. When a lift table is placed in a pit, it introduces potential pinch point between the underside of the platform and the pit wall. In order to minimize pinch point hazards, lift tables are required to either have bevel toe guards or electric toe sensors. Bevel toe guards are steel plates on the side of the table positioned at approximately a 30 degree angle towards the frame to provide p... Read More
A semi portable lift table has two rollers on one end of the frame and a removable dolly handle on the other end. With the dolly handle removed, the lift table frame sits on the floor. If the lift table is to be moved to a different location, the dolly handle is positioned lifting the frame clear of the floor on to the two fixed wheels. This permits a lift table to be portable while maintaining a comparatively low height. Due to the portability, lift tables are provided with a self-contained 115... Read More
