The golden rule of forklift operation on a ramp or incline is simple: keep the load facing uphill. Whether you are driving up or down, the forks should always point toward the top of the slope.
Driving Up an Incline
When driving up a ramp with a load, keep the forks pointing uphill. The load should be tilted back against the mast to prevent it from sliding off. Drive slowly and smoothly. Avoid sudden acceleration or jerky movements. Do not turn on the ramp. If you must change direction, drive to level ground first.
The reason is physics. The forklift balances on its front axle. When driving up a slope, the weight of the load shifts backward toward the counterweight. This is a stable configuration. The load stays secure against the mast, and the forklift maintains traction.
Driving Down an Incline
When driving down a ramp with a load, the same rule applies. Keep the forks pointing uphill. This means you will drive down the slope in reverse. Look over your shoulder in the direction of travel. Use a spotter if visibility is limited. Keep the load tilted back, not forward.
If you drive down a ramp with the forks pointing downhill, the load shifts forward away from the mast. The combined center of gravity moves toward the front axle. The forklift becomes less stable. The load can slide off the forks. And the rear wheels may lift off the ground, reducing steering control.
Empty Forklift on an Incline
When driving an empty forklift up an incline, the rule reverses. Drive up the ramp with the forks pointing downhill. The counterweight is now at the rear, and the empty forks should be positioned so the forklift remains balanced. On the way down, travel with the forks pointing downhill as well.
But the safest rule of all is simpler. Avoid driving on inclines whenever possible. If you must use a ramp, keep the load facing uphill. Drive slowly. Do not turn. And never assume you can stop and restart on a steep slope. A loaded forklift on an incline is always at the edge of stability. Respect that edge. Stay on the safe side.
