DEMONSTRATIONS were given in London recently of a vehicle lift developed by Spencer Motor Services. (Todmorden), Ltd., Stansfield Road, Todmorden, Lanes, and known as the Spencer All Angle car lift. Most interesting feature of the lift is that while the platform can be raised horizontally it is also possible to raise one side to bring the platform to an vgle of up to 450 to the horizontal.
The lifting action is by vertical square-threaded screws. These are located at the four corners of the base framework and are rotated through gearing from shafts running the length of the longitudinal members. Each shaft is driven independently by a if h.p. electric motor.
Each of the lifting platforms is in two parts pivoted together close to their ends at one side. On both platforms one of the parts is rigidly attached to the longitudinal base member and the other end is connected to the lifting screw on the opposite ;ide through a nut. The free end of the pivoted member :which is the support for the wheels or chassis of the vehicle acing lifted) is connected in a similar way to the lifting screws m the other side.
As the pairs of screws on each side can be powered separately t will be seen that the platform can be tilted in either direction lepending on which one is operated and if 'both pairs are merated together the platform will be lifted horizontally. Allen the platform is tilted provision is made for the wheels if the vehicle to be kept down by wire' ropes attached-to the vheel studs.
Maximum height of lift is 4 ft. 6 in. horizontally, at which mint the platform can be raised a further 2 ft. on one side. .ifting capacity is 3 tons and overall dimensions are 14 ft. ong by 10 ft. 2 in. wide. The platform pads can be.adjusted o take track widths from 3 ft. to 6 ft., an the rear, platform an be adjusted to cover wheelbases of
rom 6 ft.9 in. to 11 ft.
Including all necessary equipment such s jacks the Spencer AU Angle lift costs 400 ex works. The unit is freestanding hich means that there are not the usual ft installation costs. All that is needed a flat area of floor.
Jew Starter '0\ NEW starter for diesel engines has t been added to the range niade by :.A.V., Ltd. This is the C.A.V. Type L5, a 5-in, diameter axial-type starter totor and is said to be capable of 3ing the same work as most existing in. starters.
Main advantage of the SL5 starter is s reduced weight. 171b. is saved corn pared with' the C.A.V. U6 6-in, diameter unit. The SL5 is also cheaper than the 6-in. model. A publication—No. 1571—describing the pew starter is available.
Semi-trailer Leaflets LEAFLETS have been published by Scammell Lorries, Ltd., Watford, Herts, dealing with their tandem-axle. and Potutrak. (twin oscillating axle) semitrailers.
Removing Dents ATOOL -which is designed to facilitate sheet metal bodywork repairs is available from D. J. (Tipon), Ltd., 9 Curzon Street, London, W.I. . The tool is known as the Dentmaster, and cotIsiSts of a heavy sliding weight on a steel rod which has a stop on one end and a screw on the other. To repair a damaged panel, a hole is punched into the dent and the screwed end of the Dentmaster inserted. The weight is then hammered against the stop wnil the dent is removed. When the dent is sufficiently tooled, the Dentmaster is unscrewed from the hole and the body panel contoured with a plastic filler.
The tool is said to operate
efficiently. on almost all damaged bodywork. It has not, however, been tested by The Commercial Motor and there appear to be limitations to its use, as the centre of the dent only might be lifted and the screw might be pulled out of the hole before the repair was completed. On slight dents it could be useful.
