A lift truck has a lifting mast and a lifting cylinder arrangement, which is located either in front of or behind an upright of the mast and defines a dead angle for the operator of the vehicle in the operator's station. A load chain is connected to a central point of the load carrier and a chain guide roller arrangement extends obliquely to the lateral extent of the mast. The invention is applicable to masts which are nonextensible and to telescopic masts having one or more extensible sections.

Lift truck

The invention relates generally to steerable vehicles, particularly fork lift trucks, which include one or more travel drive motors adapted to be controlled in a predetermined manner, and a steerable swivelled wheel assembly. To increase the safety of such vehicle in operation, an electrically controlled drive control system is provided which is simple and free from elements that are susceptible to wear. For this purpose, two speed sensors are provided on opposite sides of the vehicle and cooperate with respective coaxial road wheels and are connected by a comparator to a switching system for controlling the travel drive, e.g., to a travel control signal generator. Elements for applying at least one additional speed-influencing input signal are associated with the comparator.

Electrically controlled travel drive control system for steerable

A drive arrangement in the chassis of an electrically powered mobile machine such as a fork lift or the like having a steerable wheel assembly at one end of the chassis and a non-steerable wheel assembly at the opposite chassis end wherein each wheel includes coupling means for connection to a driving motor and one or more driving motors may be selectively mounted in the chassis to selectively drive one, two, several or all wheels of the vehicle as may be desired.
