lifting appliance has just been produced in France under the name of the Rex, and it is capable of raising vehicles ranging from 2 tons to 6 tons in weight. It has the advantage of being mobile, whilst the lift can, without difficulty, also be employed on the upper floors of garages, etc.
The bridge and lifting arms are made from light, robust, steel pressings, and the cradles taking the lower ends of the aims rest upon east-iron feet. A small electric motor drives a cross-shaft running through the centre of the two cradles and carrying worm wheels which engage with worms on two longitudinal shafts. These worm gears are mounted on ball bearings and are enclosed in aluminium casings.
Right-hand and left-hand threads are cut on the outer portions of the shafts, and bronze nuts work on these, being articulated to the lifting arnas by means of cast-iron connecting rods.
A mechanical reversing gear is incorporated in the drive from the electric motor to the telescopic cross-shaft, two large bevels being engaged alternately with the small pinion on the motor shaft.
The cradles slide inwards or outwards on their cast-iron feet and the Rex lift thus accommodates vehicles of various tracks. When the bridge reaches its full height an automatic stop, similar to those employed in machine-tool practice, throws the lifting gear out of action.
The makers, Les Etablissements F. Huber, 11, Rue de La Barre, Enghlen lee Rains (S. et 0.). France, are seeking an English manufacturer to take up the rights for Great Britain.
