ABSTRACT:
A vibration absorber for lift trucks is provided which acts to cushion the lift mast and counteract the tendency for the truck to engage in forward and rear pitching or loping when the tires encounter a bump or other ground discontinuity. The absorber includes an accumulator hydraulically connected to the mast tilt cylinder which is gas pressurized and a conduit connecting the accumulator with the tilt cylinders. An orifice within the conduit is sized in accordance with the truck as a primary mass and the mast fork load as the secondary mass to achieve the desired shock absorbing and damping effect.
