supply of general garage equipment, Harvey Frost and Co., Ltd., 148-150, Great Portland Street, London, W.1, has specialized in this branch of the motor industry since almost the earliest years of the present century. The company, we understand, has recently been reconstituted and, as a result, certain new products will probably be announced in the near future. Already there are signs of renewed activity, the cable-drum crane illustrated on this page being an example of a recently produced item of H.F. equipment.
Its function and method of operation are evident from the picture. For loading, the drum is first hoisted by winches and block-and-pulley tackle. Then the jib structure is swung into a position that is approximately vertical, where it comes up against a stop, and the drum is lowered on to the lorry floor. Further winding gear is pr+cted for pulling the framework and the suspended drum into the vertical position. While the vehicle is travelling, the jib is swung forward, so that it rests upon the structure :t.t the front.
Adapting Existing Equipment.
There are two other new devices now' aVailable, both of which adapt existing equipment for a wider range of service. The well-known H.F. Jackcrane in its latest form is provided with an extension for the moving anti, so that it can be used for lifting gearboxes out of chassis, and the H.F. tyre regrooving tool has been modified for attachment to the concern's Robot Major tyre changer, so that a more elaborate machine is not needed. This apparatus cuts circumferential grooves on worn treads.
Both these devices deserve the consideration of maintenance engineers and, in this connection, attention may be drawn to other items of H.F. equipment that are expressly designed for heavy-vehicle usage.
For lifting rear axles having offset differentials, a trolley jack with closely set rear wheels and a 10-ft. reach is marketed. Its capacity is 4 tons and the price £15 15s.
For time saving in vehicle washing there is the Hydroforce electric-driven three-cylinder water-pumping plant, which is available from £39 upwards.
There are portable cantilever and gantry cranes for garage use, having various spans and capacities, and an 8-ton swivelling breakdown crane, which is available for £85.
Engine overhaul can be immensely facilitated by the employment of a well-designed engine stand ; the Harvey Frost Universal appliance embodies the lessons of experience. Provided with a handle-operated rotating mechanism, the 8-ft. 9-in, model is available at £17 15s, No repair shop is complete without a powerful press. The H.F. machine is a practical and robust piuce of equipment capable of exerting 30 tons pressure, whilst a feature is the inclusion of a drop hammer.
A high standard of accuracy in engine-bearing fitting is essential for efficient running and, to encourage precision in this work, adequate equipment is desirable. The Harvey Frost concern offers an assembling jig and equipment of comprehensive scope for all the operations necessary in crankshaft, big-end and main-bearing overhauling.
In addition, there are ranges of lubricating equipment and, of course, tyre-vulcanizing apparatus, together with numerous other appliances developed from practical experience to meet repair-shop requirements.
