Abstract
A load roller assembly includes a first load roller that rotates about a first axis, a second load roller that rotates about a second axis, and a third load roller that rotates about a third axis. The first and second load rollers are configured to move vertically up and down independently of the third load roller. This independent movement of the first and second axes provide more stable and controllable support to the front end of lift truck forks.
Claims21
A materials handling vehicle comprising:
- a fork connected to a vehicle frame;
- and
- a load wheel assembly mounted on the fork that includes a first load wheel that rotates about a central axis and a second load wheel that rotates about a second axis configured to move independently of the central axis.
A load roller assembly for an industrial lift truck having a vehicle frame and two forks, the load roller assembly comprising:
- a first load roller that rotates about a first forward axis closest to a front end of the forks;
- a second load roller that rotates about a second rearward axis closest to the vehicle frame;
- and
- a third load roller that rotates about a central axis located between the first and second axis.
A method for transporting goods using a pallet truck having a load wheel assembly attached to a pallet truck fork, comprising:
- rotating a central wheel of the load wheel assembly about a central axis;
- and
- rotating second and third wheels of the load wheel assembly about two associated axes configured to move up and down with respect to the central wheel.
