Abstract: A lift truck includes systems and methods for improved stability control. Stability control features reduce or eliminate motion of the truck in one or more of the X-axis, Y-axis, and Z-axis. Some embodiments may include, alone or in combination with the stability control, vibration control to further stabilize the motion of the truck.

Abstract: A control system for controlling motion of a pallet truck vehicle includes three modes of operation for controlling coasting of the vehicle. In a first, constant pressure mode, the vehicle coasts for as long as an activation button is depressed. In a second, time controlled mode, the vehicle coasts for a predetermined period of time. In the third, distance controlled mode, the vehicle coasts for a predetermined distance. Each of these functions can be activated from a remote location using a remote activation device.

Abstract: A lift truck power source includes a hybrid power supply including a storage battery, a capacitor bank, and optionally a fuel cell. The capacitor bank stores power produced during regeneration by either the truck traction system or the lift system and delivers current when current demand exceeds that delivered by the fuel cell. The storage battery or fuel cell acts as a main power supply to deliver current at a rate sufficient to power the lift truck. When the fuel cell is the main power supply, the storage battery stores power during times when current demand is less than that delivered by the fuel cell and delivers current at times when current demand is greater than that delivered by the fuel cell. When the storage battery is the main power supply, the fuel cell supplements the power delivered by the storage battery, and can also recharge the storage battery.

Abstract: A material handling vehicle incorporating integrated hydrogen storage is disclosed. The vehicle comprises a tank configured to contain hydrogen and a fuel cell coupled to the tank for receiving hydrogen from the tank and converting the hydrogen to an electric current. In various embodiments, a mast for manipulating a load, an overhead guard covering an operator area, and/or a chassis comprise a tank configured to contain hydrogen. The tank may be coupled to, integral with, and/or within the mast, overhead guard, and/or chassis and may contain a solid hydrogen carrier, gaseous hydrogen, and or liquid hydrogen.
