QUESTIONS AND ANSWERS

Answers to questions most often asked regarding Superdoks.
NOTE: Many of these questions and answers don't apply to the 1000 and 6000 Series because they sit on top of the ground.

MECHANICAL

Can the hinged bridge be mounted on the side of the platform rather than the end?
Yes, and at no additional charge. It can also be off-centered on the side. Watch the axle loading capacity over the sides, however, because it is often less than over the ends.

Can the hand rail location be changed? Yes, and at no additional charge. The rails can be put on the ends or in an "L" configuration.

Can a truck or semi trailer drive over the lift? Yes, but only at slow speeds and only when the lift is fully lowered and resting on its mechanical stops.

What happens if a truck hits the lift? It will probably be damaged, but the damage depends upon the impact forces.

Can the platforms be made smaller than shown? It depends upon the lift model. Advance can't make any platform less than 8 feet long, but we can make some as narrow as 4 feet wide. Consult the factory on this.

How long can the hinged bridge be made? 30 inches on all models except the 4000 Series. 24 inches on the 4000 Series. Consult the factory beyond this.

When should a hinged bridge be split? It depends upon the application, but generally bridges over 12 inches on the 4000 Series and 18 to 20 inches on the other models should be split.

How does the hinged bridge work? It's manually operated. When the lift is raised to truckbed level, the bridge is simply kicked over onto the truckbed. To bring the bridge back, lower the lift so the bridge begins to cam back then simply flip it back with a foot or hand.

What about full skirts or skirting on a lift? Federal regulations do not require full skirts; they require 8 inch bevel toe guards which are standard on pit mounted dock lifts. Where personnel protection is desired beyond that required by federal regulations, use Advance's electric toe guards. Fabric roller shades and accordion bellows skirting are not durable and because they do not provide a rigid physical barrier, their protection is based upon "what you can't see can't hurt you." Telescoping sheet metal skirt sections are more rigid, but are very susceptible to damage which makes them inoperable.

ELECTRICAL

Is it okay to operate the equipment on other than 230 volts/60 cycles/3 phase power? Yes. Motors and electrical components are designed to operate on 208V/220V/230V/240V/440V/ 460V/480V-60 cycle - 3 phase at no additional cost. Just specify the voltage so the correct motor overload heaters can be supplied.

Can the lifts be operated on single phase? Yes, for an additional charge, but only on 230V/60cy/1ph and only the 5 HP units. The 7-1/2 HP 4000 Series units aren't available for single phase operation due to the amperage draw on a 7-1/2 HP single phase motor.

HYDRAULIC

What oil should be used to operate the lift? Dextron III

Why isn't hydraulic fluid used? It isn't compatible with the hydraulic components and isn't as easy to buy as Dextron III motor oil.
