摘要： Steering for lift truck were the gearing in the movement transfer or translation between steering wheel and truck wheel is adapted to the work conditions by being divided into a low speed range intended for loading and unloading with high gearing and fast turning movements, and the high speed area intended for transport distances between loading and unloading places with reduced gearing. Between these speed ranges a continues transition for the gearing between the low and the high range or vise versa. The gearing in low and high speed ranges, respectively, may have a comparatively small speed influence or even be constant, whereas the gearing change quickly with the speed in the intermediate range.

摘要： Device for the reduction of shocks in the lifting movement at a lifting truck of the kind that includes a lifting fork carriage (5) moveable vertically in a mast part (4) that in turn is movable and where the fork carriage in the mast part is lifted by means of a hydraulic cylinder (7) fastened in the upper end of the mast part. Its piston rod (9) is extendable downwards and over a pulley (8) in the lower end of the piston rod a chain (6) runs that from an upper fastening point in the mast part (4) runs down around the pulley (8) and up again over another pulley (15) fastened in the upper end of the mast part and then once again downwards to be fastened in the fork carriage (5). The hydraulic cylinders of the fork carriage and the mast parts are coupled in parallel but have such relative cross sections that the cylinder (7) of the fork carriage have smaller pressure requirement than the mast cylinders. In the frame of the truck or in a mast part (2) fastened to the truck frame a sensor (11) is arranged close to the lower end position of the piston rod (8) and for cooperating with this in such a way that when the piston rod (8) approaches its lower end position , that is the lifting carriage is approaching its upper end position in the mast part, the sensor is triggered. The sensor is coupled to the hydraulic means that feed hydraulic oil to the hydraulic cylinder reducing the oil flow so that the speed of the carriage is reduced close to the end of the travel of the carriage in the frame part (4) and at lowering the mast movement speed is reduced in the vicinity of the lower end position of the mast parts.
