Ramp Operations

When driving a powered industrial truck on a ramp or incline, certain precautions need to be taken. OSHA regulations 1910.178 (n)(i) state:

"When ascending or descending a grade in excess of 10 percent, loaded trucks shall be driven with the load upgrade."

 



Staying Safe on Ramps and Inclines

Ramps or inclines in your facilities present hazards to your forklift operators. This should be brought out when training your forklift operators. On all sit-down style forklifts, Class 1, 4, & 5, this could be battery, propane, gas or diesel powered forklifts, the loads must face upgrade.

Another class 1 truck that falls into this category is a stand-up counterbalance forklift. This style forklift has no outriggers on it that stick out to the sides and doesn’t have a reach mechanism. The mast generally lifts and tilts loads like a sit-down forklift except you stand up in it to drive it. This type of forklift follows the same rules as the sit-down style forklifts on a ramp or incline. The load must face uphill.

When traveling with no load on these trucks, ascending or descending an incline, the manufacturers of most forklifts highly recommend that you travel with forks facing downhill (Class 1, 4, and 5).

Another style forklift is the reach truck, or Class 2. This style of forklift has the outriggers off to the sides and could have a reach mechanism on it. The mast is usually fixed and the tilting occurs out at the fork carriage. This style truck is NOT recommended for ramp use. Its main use is hard level surfaces. If you drive this on a ramp or incline, the outriggers could bottom out at the top of the ramp. Another forklift that falls into this category is the order picker or man-up style; this should also NEVER be used on a ramp.

A Class 3 style forklift is known as a powered pallet jack. You generally walk off to the sides when using this type of truck to avoid injury to your foot or leg. On a ramp, if the load is secure and you can see around it, or if the pallet truck has no load on it, then stay on the high side of the pallet jack and face the forks downhill.

When walking up the incline, the operator is safely off to the side with the pallet truck trailing behind. When coming down the ramp, with no load or a secure load, then have the pallet truck out in front of you. If the operator should ever trip and fall, the pallet truck will not roll over them.

If for some reason the load the operator is carrying is unstable or blocks the forward view of the operator and must face uphill, then the operator MUST stand safely off to the side of the pallet truck and operate it with one hand. This way, if the operator trips or falls, the pallet truck is off to the side and not in front of the operator.

A class 6 style truck is also known as a tow tractor. You see many of these at airports towing luggage carts. If these operate on a ramp or incline ascending or descending, always have the load trailing behind the tow tractor.

More Training Tips – Some final training tips operators should know about operating on ramps or inclines include the following:

  • NEVER turn on a ramp or incline. This will cause the truck to tip over and serious injury or death can occur.

  • Operators should never park on a ramp or incline. If you must, then the operator should make sure the parking brake works, and the wheels of the forklift should also be chocked.

  • Never depend on the parking brake only to hold on a ramp or incline a forklift that weighs 8,000 pounds or more.

  • Make sure your forks are just high enough to clear the travel surface.

  • Pedestrians and forklifts should never occupy a ramp or incline at the same time.

  • If the operator of a Class 1,4, & 5 is carrying a load that blocks their forward vision on level surfaces, they are taught to drive in reverse. But when approaching a ramp or incline, that load must face uphill.

  • The operator should be taught to get a spotter to help guide them up incline. The spotter must stand safely off to the side of the forklift in full view of the forklift operator. The operator of the forklift will follow the direction of the spotter; they should establish some type of hand signals in case it is loud or noisy in the work area. The spotter will wave away any pedestrians who are in the way, and will also insure that the operator doesn’t get too close to the edge of the ramp or incline. Once the forklift gets to the top of the ramp, the operator can safely turn the forklift around and travel in reverse again. If, for some reason, the load has to face forward on a level surface, use a spotter to get the load safely to where it belongs.

  • All forklifts on a ramp should be driven slowly until they get to level ground.

  • Ramps and inclines are a hazard in your facility. Great care should be taken when traveling on them. Proper training should be in place for operations in these types of areas. Always check with the operator’s manual of any forklift for specific instructions when operating on a ramp or incline.

Overheating Diagnosis

July's Training Tip is on engine overheating problems and how to identify the cause.

Summer is here and with it comes the potential for overheating issues. Every complaint needs to be considered and investigated carefully. However, there are many factors that, alone or in combination with others, may contribute to the overheating condition. It is first necessary to always isolate those factors that are causing the condition. Be mindful that in many cases, the causes of overheating are due to factors other than defects in materials or workmanship. Listed below are some of the most common factors encountered.

  • Radiator or radiator screen is clogged.

  • Inching pedal is misadjusted.

  • Operator is "riding" the inching pedal.

  • Attachments with low flow requirements and heavy usage have been installed. This causes the hydraulic oil to heat to the extent that it actually heats the coolant in the radiator. In this case, a flow control valve may be required.

  • Engine timing is incorrect.

  • Engine performance is poor due to fouled plugs, valve wear, etc.

  • Collapsed radiator hoses.

  • Stuck or inoperative thermostat.

  • Broken fan blades.

  • Loose fan belt.

  • Making long runs in reverse (cancels cooling effect of fan).

  • Extremely high ambient temperatures in application.

  • Running units with over capacity loads.

  • Extensive ramp use.

These are just a few of the possible contributing factors. It is important to eliminate any of these to narrow the possibilities to the real problem area.
