One-man demountable body system speeds turnround

ANEW demountable body loading and unloading system was demonstrated last week by the manufacturer, Hazlemere Motor Co. (Waltham Abbey) Ltd.
A skeletal subframe is fitted to the vehicle chassis and carries a horizontally mounted guide wheel which engages with a longitudinal channel in the underframe of the body, to provide location. The front posts of the subframe engage in locating forks on the container bulkhead; when the body is lowered into position on the frame, high-tensile steel pins automatically engage to hold it firmly in place on the chassis.
Incorporated in the underframe are two box-section cross-members in which are inserted screw lifting jacks with landing wheels. To remove the body from the subframe, the securing bolts are unfastened and the jacks are placed in position and then wound down some 4in. to 5in. (shafts transmit the drive across the body to the opposite jacking leg). The vehicle can then be driven clear.
It is claimed that one man can mount or demount the body very quickly, and that taxation weight is low because the container body is not included, but only the subframe.
The particular vehicle illustrated has been supplied to Alston's (Long Melford) Ltd., which worked closely with Hazlemere in the design.
• THE PROPOSED LINE for the first section (2+ miles near Thorne) of M18 motorway extension in the West Riding of Yorkshire was published on Monday by the Minister of Transport. The 18-mile extension will form part of the new network to improve Humberside's connections with the national motorway system and the Great North Road (Al). SAMPLE STUDIES had shown that in about 10 per cent of the injury accidents involving articulated vehicles, jack-knifing occurred before the accident, said Mr. John Morris, Parliamentary Secretary to the Ministry of Transport, in the Commons.
This did not, of course, mean that jackknifing had necessarily been a cause of these accidents.
