An impressive turn out of Allied Concrete Mack Metroliner ready mix concrete trucks in the parade.

Certified Concrete Ltd, Invercargill fifties. New Zealand relied on the GMC 6x6 ex military trucks left on our shores after world war 2 for a huge variety of purposes.

Certified Concrete, Auckland branch, Commer CA model TS3 diesel with forward discharge mixer.

Firth Concrete Products Commer CC type TS3 diesel 6 wheeler with hydraulic chassis mounted crane and 3 equally spaced axles trailer loaded with concrete water troughs. If this truck was a factory 6x4, it would be a Commer-Unipower with the conversion engineered by Universal Power Drives of Perivale, Middlesex, England-(Unipower). Commer-Unipowers used tandem Eaton 30DT 2 speed axles and Hendrickson walking beam suspension. That load would surely have provided a good workout for the TS3 diesel.

Winstone Ltd. Bedford S model furniture van with Certified Concrete Commer ready mix trucks and a Winstone's Bedford J2 in the background.

Two TS3 diesel powered Commer Mk.5 concrete mixer trucks of Certified Concrete, Wellington. Certified Concrete trucks with their red cabs and yellow bowls were a distinctive sight and sound if they were TS3 powered Commers in Auckland, Wellington and Christchurch in the later 1950s-1970s era.

5 Certified Concrete Mk.5 mixer trucks. The 3 closest to the camera are petrol engined trucks with Commer's 290 cubic inches sloper/slanted 6 cylinder engine rated at 111 horsepower in this model. Notice the different methods of powering the bowls, the first truck appears to have an engine powered bowl, while the truck next to it seems to have a hydraulic setup using hydraulic rams.

A Certified Concrete CA series TS3 Commer 6 wheeler mixer truck. The CA series-(introduced in 1962) were the first to use the new 4 headlight cab manufactured for Commer by Joseph Sankey of Birmingham. The smaller cabs used on the earlier 7 tonners was manufactured in house by B.L.S.P.-British Light Steel Pressings, a division of the Rootes Group.

A Mk.4 Commer petrol of Certified Concrete, Auckland delivering concrete to a building site.

A Mk.1 Commer R715 of Certified Concrete. The R7 series was introduced in 1948 and was a modern and distinctive design for a British truck of the time. The R7 series was built until 1953-54 through Mk1 and Mk.2 models. There was no diesel engine option for these earlier 7 ton Commers, all had the 109 horsepower 290 sloper petrol motor. In 1954 the C series or Mk.3 7 tonner was introduced with the same cab. The introduction of the C series coincided with the release of the 105 horsepower Rootes TS3 diesel engine in CD models. The C, CX, CY, CD, CDY series were built through Mk.4 and Mk.5 models until c.1962. The second or third letter referred to the gearbox fitted with the Y indicating a 5 speed constant mesh gearbox.

Certified Concrete International LF174 mixer truck. Notice how this truck has 10 stud Budd wheels, while Dale's Transport's LF174 has cast spoke wheels. The LF170 series-(built 1950-53) replaced the earlier KB6F models-(built 1947-49) in the International truck lineup. LF174 trucks were powered by an International Super Blue Diamond 269 petrol engine, a modified version of the KB6F Blue Diamond BD269 engine.

Bedford RLHC3 concrete mixer truck of Winstone Concrete, Hamilton. The RL Bedford 4x4 was one of the first postwar factory 4 wheel drive trucks available new in New Zealand.

A Mk.5 Commer petrol ready mix truck of Certified Concrete. The Mk.5 7 tonners with a one piece windscreen and raised roofline were the last to use the B.L.S.P.-British Light Steel Pressings cab.

Concrete and Metals, Motueka, International Loadstar F1800. This truck is an early model F1800 as it is on 10 stud Budd wheels. The Loadstar series was introduced in 1962 and only the first of the series sold here in c.1962-63 were on Budd wheels. All later trucks were on cast spoke wheels.

A very smart GMC CCKW353 6x6 concrete mixer truck with front mounted winch belonging to M.E. Roberts & Co., Building Contractors of Hokitika, Westland. It appears that the mixer bowl is driven by a Ford diesel engine as it has a Fordson tractor radiator surround and hood.

6 GMC CCKW 6x6 concrete mixer trucks of Certified Concrete, Invercargill. The trucks were owned by Southland Sand & Gravel and contracted to Certified.

Ready-Mix Concrete, Blenheim, fleet-an International LF174 6x4 and 2 GMC CCKW 6x6 mixer trucks.

Firth Concrete, Rotorua, International Loadstar F1800 concrete mixer truck. Another early model F1800 on 10 stud Budd wheels.

Another International Loadstar F1800 concrete mixer truck, this one belonged to Ashby Bros., earthmoving, roading and ready mix concrete contractors from Christchurch. In this scene it is delivering concrete to a building construction job at the new University of Canterbury campus at Ilam in Christchurch. The P.& H. mobile crane on what is probably a Tidd carrier was operated by D.F. Nuttall of Christchurch.
