ABSTRACT:
An arrangement in industrial trucks of the kind which include a chassis (3) carried by support wheels (5, 6) which lack spring suspension, and driven by a sprung drive-wheel (7) arranged between two support wheels. A hydraulically operable load carrying device (2) is provided for lifting primarily goods-laden pallets. The sprung movement of the drive-wheel (7) relative to the chassis is effected with the aid of a spring assembly (22) which includes link arms (25, 26) and a spring (24) both being arranged between the chassis and the drive-wheel. The spring (24) includes a hydraulic working piston-cylinder device (27) by means of which the spring assembly can be given a desired spring bias or spring force. The piston-cylinder device is connected to the hydraulic system of the load carrying device in a manner to increase automatically the spring bias, and therewith the pressure exerted by the drive-wheel against the floor or like surface when the load carried increases.
