A ramp, slope or incline is defined as an angle that exceeds 10%, or approximately one foot rise for every ten feet of ramp or incline. OSHA 1910.178(n)(7) addresses regulations for forklift ramps, slopes or inclines that must be followed any time a powered industrial truck is on a defined incline.

OSHA Regulations for Ramps

1910.178(n)(7)(i) When ascending or descending grades in excess of 10 percent, loaded trucks shall be driven with the load upgrade.

1910.178(n)(ii) On all grades the load and load engaging means shall be tilted back if applicable, and raised only as far as necessary to clear the road surface.

How Ramps Affect Forklifts

Climbing excessive grades can have a negative effect on battery cycle time, fuel consumption, component temperature, longevity and reliability of the machine. While the ability to reliably climb a ramp is important, safely descending a ramp when carrying heavy loads is equally concerning. The forklift must be able to safely stop on the required grade. Operators should be trained to follow specific travel rules for their own safety.

Forklift Gradeability

Gradeability ratings apply to a particular make and model of machine and are legitimately supplied only by the manufacturer. The ratings identify on which grade a machine is capable of climbing and stopping with a full capacity load. For example, a Toyota 8FBCU25 forklift is rated at approximately 20% which is only 12 degrees. However, some 4-wheel drive rough terrain forklifts have as much as a 30-40% gradeability rating.

Many times forklift gradeability is rated on degree of angle but you may also calculate the percentage by measuring the height and length of the ramp at your facility.

Forklifts and LP Gas Storage

A large percentage of forklifts operated in the U.S. are fueled by LP, also known as liquefied petroleum. LP gas is a flammable mixture of hydrocarbon gases, primarily propane and butane. One gallon of LP gas is equivalent to 270 gallons of vapor; therefore, an 8 gallon cylinder of LP gas has a capacity of […]
