IN THE new four-compartment 667 Cu. ft. bulk transporter produced by Bopen Ltd. of Wisbech, Cambs, each partition can be located in any one of five positions, so that the capacity of a compartment can be varied from I ton to 21 tons.
The body is of light alloy and is mounted on a Ford D1000 16-ton-gross chassis. An unladen weight of around 6 tons 12cwt gives a payload of 9 tons 8cwt.
The body is designed to carry animal feed and grain which is discharged pneumatically by means of a Bopen rotary feeder of the drop-through type that can discharge from either side. A Godfrey L800 Mk2 blower is driven from a Martin-Harper driveline power take-off. The lifting gear is an Edbro front-of-body twin-ram type, while the lifting frame is of steel construction.
B open instructs drivers how to operate the pneumatic system to give minimal degradation (about 1 per cent) which depends on the correct matching of the quantity of air sup plied to the flow of material. It states that excessive degradation is normally caused by an excess of air.
