TEST METHOD NO. 1
MAXIMUM LIFT HEIGHT - LOW ENGAGEMENT HEIGHT - FORK REACH
1.
TEST COURSE:
a. Level flat surface.
b. Level, flat surface with sharp drop-off over an edge.
2.
TEST APPARATUS:
a. Linear measurement equipment.
b. Liquid level or clinometer.
c. Straight edge.
3.
TEST PROCEDURE:
a. Lift the rated load to the full extent of boom travel. Adjust
the fork tilt to level the load. Measure the true vertical
distance from the surface to the top surface of the forks
(this is the maximum lift height).
b. Position the forklift on the edge of the drop-off. Lower the
forks (without load) over the edge to the full extent of boom
travel. Adjust the fork tilt to level the top surface of the
forks. Measure the true vertical distance between the surface
on which the forklift is positioned and the top surface of the
fork. (This is the low engagement height).
c. Raise forks to 60 in. (2 in) above the ground. Measure the
horizontal distance from the vertical plane, established by
placing a straightedge against the forward most part of the
front tires, to the heel, front face, of the fork.
