Manufacturer description

The AEC Dumper Truck or to give it its full title – 1965 10 cu. Yd 690 Dump Truck was  produced on an Aveling Barford and a Scammell LD55 chassis. They would have had a badge on the front bar or grille denoting AEC, AB or Scammell but to make full use of the new tooling the badge has been omitted so Oxford can produce all three variants.

The specifications listed in the sales brochure of the period gave the in-depth details of vehicle components and operational attributes. The engine was a 4-stroke, 6-cylinder, vertical, direct injection diesel. Output was 192 bhp at 2000 rpm with a maximum torque of 557 Lh-ft (77kg-m) at 1100 rpm. The clutch was a hydraulically operated single dry plate 16” in diameter while the gearbox featured 5 forward speed and 1 reverse gear, all constant mesh, direct mounted with the engine. The front suspension had 3 ½”wide inverted semi-elliptical leaf springs with rubber pump stops and telescopic double acting hydraulic damper. The rear bogie had 3 ½” wide inverted semi-elliptical leaf springs pivoted at their centres on a transverse tube, mounted in cast steel brackets bolted on to the chassis frame.

The frame was of bolted construction and the standard wheels and tyre equipment comprised 14-ply Dunlop ‘Roadtrak Majors’ on the front and ‘Dunlop Powergate’ 20-ply on the back. The twin-ram, 3-stage tipping gear gave a 70 ͦ angle of tip in 12-14 seconds with double-acting cylinders on the last two stages. The hoist control gave four positions – lift, hold, power down and float.

An emergency brake contributed to the safety features mechanically operating the brake shoes on the rear bogie by means of a multiple pull handbrake lever.

Our detailed model, registered SCK 36K contains all the physical features of the original and appears in a black and yellow scheme, as used by Wimpey, the famous British construction company whose name is printed in black on the cab doors and on the sides of the tipper. The cab roof, nudge bars and the bumper are painted white in sharp contrast to the black chassis and wheels, which have been treated to silver inserts. Note the addition of a beacon on the roof too. The truck interior is finished in black.

Oxford Diecast AEC 690 Dumper Truck (Wimpey livery)

Manufacturer part number 76ACD001. The model represents a 1965 10 cu yd 690 dump truck in British Rail Blue (pre‑TOPS) livery. The original vehicle was built on an Aveling Barford or a Scammell LD55 chassis; the badge on the front grille was omitted to allow Oxford to produce three variants from the same tooling.

Technical specifications include a 4‑stroke six‑cylinder vertical direct‑injection diesel engine delivering 192 bhp at 2000 rpm and a maximum torque of 557 lb‑ft (77 kg‑m) at 1100 rpm. It has a hydraulically operated single dry‑plate clutch (16 in diameter) and a constant‑mesh gearbox with five forward speeds and one reverse. The front suspension uses 3½ in wide inverted semi‑elliptical leaf springs with rubber pump stops and telescopic double‑acting hydraulic dampers; the rear bogie employs similar springs pivoted on a transverse tube. The bolted frame carries 14‑ply Dunlop “Roadtrak Majors” tyres at the front and 20‑ply Dunlop “Powergate” tyres at the rear. The twin‑ram, three‑stage tipping gear achieves a 70° tip in 12‑14 seconds and is controlled by four positions – lift, hold, power down and float. An emergency hand‑brake operates the rear‑bogie brake shoes via a multiple‑pull lever.

The detailed model, registered SCK 36K, reproduces all physical features of the original and is finished in the Wimpey colour scheme: black and yellow bodywork with white cab roof, nudge bars and bumper, silver‑insert wheels and a roof‑mounted beacon. The cab interior is black and the name “Wimpey” is printed in black on the cab doors and on the sides of the tipper.
