Frequently Asked Questions

Can AGVs operate on ramps?

Yes, however ramp conditions greatly affect AGV capacity ratings. Most facility ramps vary between 2-10%. AGV unit load carriers are generally allowed to operate on ramps with no more that about 5% inclines. In addition, the level rated capacity of most unit load carriers will be reduced by up to 70% on ramps of 3-5%, depending on the length of the ramp. This means a 4,000 pound rated unit load carrier would only be allowed to handle 1,200 pounds or less when ramps are involved in the system.

Towing AGVs are capable of handling longer and steeper ramps than unit load carriers. They too must be derated for ramp operation. A 30,000 pound towing capacity AGV tow vehicle would be rated for about 10,000-15,000 pounds on a typical 10% ramp. In general, AGV tow vehicles with rear wheel drive systems do better in ramp applications than those with only single front wheel drive construction. Rear wheel drive provides better traction going up the ramp and better stopping performance should the bumper be activated going down the ramp.

Ramp surfaces need to be kept dry. A rough brushed concrete surface is best for traction.
