摘要： A wheel assembly includes a constant force mechanism and a wheel coupled to the constant force mechanism. The wheel is displaceable in at least one dimension, and the constant force mechanism imparts a substantially constant force on the wheel in the dimension. In one aspect, the wheel is displaceable in a first regime and a second regime. For a wheel displacement in the first regime, the constant force mechanism imparts a substantially constant force on the wheel, and for a wheel displacement in the second regime, the constant force mechanism imparts a variable force on the wheel. The variable force can be linear or non-linear to the magnitude of the displacement in the second regime and is equal to or greater than the substantially constant force.

摘要： An electric actuator replaces the hydraulic reach actuator in a reach carriage for a reach truck. The electric actuator may be a linear actuator and may have a rotary motor and a combination ball screw and ball assembly for converting the rotary motion of the motor into linear motion to extend and retract a rod. A force limiter can be disposed between the motor and the ball screw, and may be coupled to the motor and the ball screw. The force limiter prevents a contact force on the rod from damaging the motor. The force limiter allows the reach carriage to operate normally until a contact force occurs, then disengages if a threshold level of force is exceeded. The force limiter may be a torque limiter that automatically reengages after the contact force has attenuated.

摘要： Systems and methods maintain a lift truck within defined bounds. A controller analyzes actual and/or predicted lift truck behavior, and based on the analyzed lift truck behavior, the controller control at least one lift truck performance parameter. The performance parameter is controlled to maintain the lift truck center of gravity within a stability map, the stability map to define a three-dimensional range of center of gravity positions that maintains lift truck stability. The performance parameter is also controlled to maintain an intended path of the lift truck within an allowable deviation map, the allowable deviation map defining a two-dimensional envelope of allowable lift truck travel deviation from the intended path of the lift truck.
