POST OFFICE engineers from all over the country visited an exhibition at Watford this week organized by the P.O. Engineering Dept., to see the latest trends and developments in a wide range of equipment and vehicles used for external construction work. An exhibit which attracted much attention was a line construction unit, the Tel-E-Lect, which is of American design and manufacture and is mounted on a diesel-engined B.M.C. 5-7-ton chassis. The unit incorporates a winch, a derrick with boom-extending stinger which rotates 360 degrees at a height of 33 ft. and a radius of 23 ft., a pole hole borer mounted on the derrick and a glassfibre personnel bucket mounted at the end of the stinger.
