The short answer is yes and here’s the reason why. Typically dock levelers are installed in a 3 sided pit at the loading dock area. To allow for operating clearances there is usually a 1” gap between the dock leveler platform and the side walls of the pit. When the dock leveler is in the closed stored closed position and the overhead door is closed these 1” side gaps allow cold exterior air to blow up from the dock leveler pit into the building.  Traditional efforts to conserve energy at the loading dock have been to close these two 1” side gaps with some form of
That’s a good question; the frequency of operation at the dock area determines the recommended maintenance schedule. In most applications mechanical dock levelers should receive a spring and fall maintenance inspection. The inspection consists of first a functionality test followed by visually checking all of the weldments and removing all excess debris from the pit.  Perform any adjustments that may be required to the lift springs, lip actuator springs and hold down mechanism.  Lubricate th...

Hot dip galvanizing is often specified in highly corrosive or repeated wash down applications. Common applications would be food processing facilities and chemical processing facilities. Preparing for the hot dip galvanizing process the equipment is built, tested then dismantled and sent to the galvanizer in sub-assemblies. The sub-assemblies are first dipped into an acid solution for cleaning, once cleaned dipped into a hot (approximately 850 degree) molten zinc galvanizing solution. The extreme heat of the galvanizing solution and the immersion process ensures that the complete sub assembly ... Read More
Although vertical storing dock levelers are initially more expensive they can actually be more cost effective in the long run depending on the application. Vertical storing dock levelers are more energy efficient because when they are in the stored position with the overhead door closed the chance of energy loss is minimized. Vertical storing dock levelers also reduce the risk of vermin entry which is very important in any food industry.
LTNI stands for “Lift and Tilt Non-Intrusive”. Components are often shipped in bins and during the loading and unloading process a combination of a lift table and a tilter positions the bin in the most ergonomically correct position for the operator. Conventional tilters force the operator to step back when the bin is tilted towards them. In many applications where there are no space restrictions this model of lift and tilt works well.

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 the... Read More
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 ...

Declining driveway approaches are very common at the loading dock area. Incoming vehicles are backed into position at an angle determined by the percentage of the decline. The most effective method to address this situation is to project the dock leveler pit forward. The amount of projection is determined by the percentage of the driveway decline. Projecting the dock leveler pit at the onset eliminates damage caused by vehicle impact to the building and the resultant need for aftermarket bumper extensions, longer hinged lip assemblies etc. to address this condition.

Preventative maintenance for dock equipment is highly recommended. The more you maintain your dock equipment, the better and longer your equipment will last. Regular maintenance increases employee safety, helps to control repair costs and assists in avoiding company down times. When unexpected maintenance occurs, it can have a long chain of unexpected delays by stopping goods from entering or leaving a facility. Maintaining your equipment on a regular basis can minimize these delays and improve safety at the loading dock area. Contact a Pentalift Sales Re... Read More
