for municipal purposes
A Forward-control 3-tonner
Designed -Primarily for Refuse Bodies and Gully and Cesspoolemptying Equipment, and Priced
in Chassis Form at £325
TO be shown for the first time at the forthcoming exhibition of municipal vehicles and appliances, at the confer
ence of the Institute of Public Cleansing, a new model announced by Karrier
Motors Successors, Ltd., Huddersfield, embodies many features which make it particularly, suited to municipal work. At the same time a review of the new chassis, which is to he known as thk. C.K. 3-type makes it clear that its usefulness in other spheres of operation should not be overlooked.
Designed for a pay-load of 3 tons, the chassis layout provides for the maxi mum body space, with the minimum overhang, and the question of law loading has been carefully studied. As a result of setting the engine well for ward, large bulky loads can be accommodated and the machine is thus able to operate at its full rated capacity. Owing to the small wheels used, it is also possible to obtain a floor devoid of wheel-arch obstructions.
The chassis •incorporates a six-cylindercd engine having a bore and stroke of 78 ram. and 106 min. respectively, giving a piston-swept volume of 3.04 litres. It is rated at 22.6 h.p. and de velops 24 b.h.p. at 1,000 r.p,m. and.
51 b.h.p. at 2,300 r.p.m. Side valves are operated by flat tappets 'having chilled iron heads. The cylinders and top half of the crankcase are in the form of a single casting of rigid construction, and the pistons are of cast-iron of lightweight design.
In view of the constant stopping and starting required on municipal work, magneto ignition has been preferred to the coil system, and for the same reason a Solex self-starting carburetter is fitted.
Formed as a unit with the engine, is the single-dry-plate clutch and the four
forward-speed-and-reverse gearbox. Both the gearbox mainshaft and layshalt are kept as short as possible and are carried on large-diameter ball and roller bearings. The drive is taken to the rear axle by means of a tubular propeller shaft, equipped at each end with needle-roller universal joints.
Of the fully floating type, the rearaxle drive is by spiral bevel, both the pinion and wheel being mounted on adjustable taper bearings with a spigot bearing behind the pinion. The differential unit may easily be removed from the axle, whilst the differential bearings can be adjusted after removing the rear cover.
The well-braced frame is of hightensile steel and has a maximum depth of 7 ins. Bolts are used wherever possible in place of rivets.
Suspension is by semi-elliptic springs both front and rear, those at the rear being of the progressive type. As previously mentioned, small wheel's are used, these being of the detachabledisc pattern shod with 27-in. by 6-in. reinforced heavy-duty tyres.
Self-energizing brakes on all four wheels are operated by both the pedal and lever, and an independent adjustment is provided for each set of shoes.
The chassis is available in three lengths of wheelbase, namely: 9 ft. 3 ins., 10 ft. 3 ins. and 11 ft 3 ins., giving a permissible body space of 14 ft,, 15 ft. 6 ins., and 17 ft. 6 ins. respectively, The track in each case is 5 ft. 4i ins, at the front and 5 it. 21 ins. at the rear and the frame height when laden is 2 ft. 1 in. The unladen chassis weights are 32 cwt., 33 cwt. and 34 cwt. respectively.
Full equipment is provided, and this attractive chassis, which should have a wide appeal, is to be sold at £325.
