The load-bearing fork members can be mounted on the first and second beams. The fork members can be displaced along the length of the beams. The fork members have first and second legs that extend in separate vertical planes. The fork members are designed such that the distance between the first legs is greater than the distance between the second legs when the two forks are mounted in place on the rack. The spacer elements have fastening devices which are intended to releaseably fasten the fork lift rack to a lift mechanism, the upper beam has a web and a flange which are joined to each other at an angle &agr; different from 90°. The upper beam is joined to each spacer element via the web. The web is directed away from the lower beam.

Abstract: A brake arrangement for a machine that includes a locking element adapted to engage with an output shaft from a gearbox. The gearbox comprising at least two gearwheels utilized to obtain different gears. A gear clutch is provided for each gearwheel and is adapted to engage and disengage a respective gearwheel depending on the operating conditions of the machine. A control unit is arranged to control the gear clutches so that the gear clutches simultaneously engage at least two of the gearwheels thus to braking the output shaft. The control unit is adapted to control the locking element so that the locking element engages with the output shaft when the output shaft is at a standstill thereby causing the output shaft to be prevented from rotating when the locking element engages with the output shaft.
