Waste Truck with Rear Bin Loader

Waste and refuse work is the hardest duty a machine of this size can be given, and not because of the loads. It is the stop-start pattern, the wet material, the cleaning and the number of times the body goes up in a day. This page sets out what that asks of the specification, the four configurations built and shipped here, and the routines that keep a waste truck working rather than merely running.

What waste work asks of the machine

Three characteristics define the duty. The first is the cycle: a collection round is a long sequence of stops and starts rather than a haul, and the machine spends more time stationary and manoeuvring than travelling. The second is the material: it is wet, it varies, and it leaves residue in the body. The third is the day: the body is lifted many more times than on a haulage job, which puts the tipping gear and its mountings at the centre of the maintenance picture rather than at the edge of it.

The body, the tailgate and what is carried

Every configuration has a tailgate with a self-dumping function, which starts the load leaving before the body reaches full height and shortens the time the machine spends raised. The 22.Luxury adds a side-opening rear body tailgate with a cab ladder. Where a round needs a particular loading arrangement at the rear — bins, containers or hand loading — that is confirmed as part of the build rather than assumed, because it is the one part of a waste specification that cannot be inferred from the rest of the sheet.

Wet material, residue and cleaning

Wet waste behaves differently from fill. It holds together, it does not discharge cleanly at the angle that fill does, and what is left in the body becomes a problem the next day rather than a nuisance today. Cleaning the body out at the end of a round is part of the job rather than an optional extra, and a floor left with residue carries it into the next load. On a machine doing this work daily, the body floor and the tailgate seal are the two places worth watching.

The four configurations

The range covers a single-cylinder 25 hp on the 4.Upgraded, a single-cylinder 28 hp on the 6.Standard and the 7.Upgraded, and a four-cylinder 4105 turbocharged engine on the 22.Luxury. On a collection round the engine matters less than on a haul: the route is stop-start, the speed is low and the limit is the round rather than the gradient. The turbocharged 4105 is the one where the machine also travels a distance to a disposal point, or where the round includes a sustained climb.

Drive arrangements and the front axle clutch

The 4.Upgraded, the 6.Standard and the 7.Upgraded use a full-time gearbox with four-wheel drive, and the 4.Upgraded and the 7.Upgraded add a front axle clutch, which lets the driver disengage the front axle on firm sections. The 22.Luxury uses the Model 145 part-time gearbox with four-wheel drive. All four carry high and low range with a crawler gear, and on a round the crawler gear is what makes creeping between stops possible without riding the brakes or slipping the clutch.

Frame, body, axles and brakes

Three of the four sit on the reinforced 60 x 140 mm square tube frame with a rear body 2.2 m long by 1.5 m wide and 0.45 m high, a front axle 212 and a rear axle 130. The 22.Luxury uses the reinforced 80 x 180 mm square tube frame with a 3.0 m by 2.2 m body of the same depth, a reinforced ISUZU-pattern front axle and a reinforced 1080 rear axle. Air cut-off brakes are fitted to the 22.Luxury and oil brakes to the other three, and every body is lifted by twin hydraulic rams.

Tyres and the surfaces a round covers

The 4.Upgraded, the 6.Standard and the 7.Upgraded run four 700-16 mountain tyres and the 22.Luxury runs six 825R16 steel-belted radial tyres. A collection round covers more surface types than a haulage route: tarmac, a yard, a track and sometimes soft ground at the disposal point. The mountain pattern clears mud and loose material at the soft end; the radial suits the road sections where the machine covers distance. Six tyres spread the load across more ground, which matters on a soft tipping area.

Cab and the hours on a round

The 22.Luxury, the 4.Upgraded and the 7.Upgraded have a fully enclosed cab and the 6.Standard a simple cab. All four carry hydraulic power steering, a two-person comfort seat and twin-battery electric start. On waste work the enclosure is worth having for a reason that has nothing to do with weather: the driver is in and out of the cab all day, and a cab that is easy to leave and re-enter, with controls in the same place every time, is what keeps a round on schedule.

Working in built-up areas

Collection work happens where people are. That puts the emphasis on manoeuvrability and on predictability rather than on speed: power steering, good sight lines and low-speed control in the crawler gear are the specification that helps. The bonnet is the panel a driver sights over when placing the machine, and all four use the square-nose bonnet. Reversing is the manoeuvre that deserves the most care on a round, and a machine that turns tightly saves more time than one that travels quickly between stops.

At the disposal point

The disposal point is where the day is won or lost. A body raised on ground that is not level puts the weight onto the downhill side, and the safe habit is to position pointing up or down the slope rather than across it. Twin rams lift an uneven load without twisting the body, which is the normal case with wet material that has settled to one side. Where the load sticks, the answer is to lower the body and reposition rather than to raise it further.

Maintenance on a waste machine

Maintenance on this duty is dominated by the number of times the body goes up. The ram mountings, the hoses where they run past the body, the tailgate latch and the body floor are the four items to check, and they deserve a look at the start of each shift rather than at the end of each week. Contaminated hydraulic oil is what shortens the life of the pump and the rams, and on a machine tipping dozens of times a day a small weep found early is a hose rather than a machine off the round.

Cleaning is maintenance too. A body washed out at the end of a round, a tailgate that seals, and a floor that is not left carrying residue are what keep the machine usable the following morning, and they take a few minutes rather than a day.

Route planning and the number of stops

A round is planned rather than driven. The useful questions are how many stops there are, how long the machine is stationary at each one, where the disposal point sits relative to the route, and whether there is a section that is only passable in one direction. Those answers settle the body size and the turning requirement, and they are worth writing down before the order rather than discovering on the first morning that the machine needs three attempts at a turn that happens twenty times a day.

Daily checks before the round

A walk-around at the start of each shift should cover the body and ram mountings, the hydraulic hoses, tyre condition and pressures, brake response and fluid levels, and the tailgate latch. Air filtration needs more frequent attention in dust, and after the disposal point the brakes should be checked before the machine re-enters traffic. Those checks are what keep a waste truck available on the day it is needed rather than the day after.

Parts, service and the local network

The parts worth holding for a machine on this duty are the ones that stop it: hoses, brake linings, mounting bushes, filters and tyres. Which of them the local network already carries is worth establishing before the machine ships rather than during the first breakdown, because a machine built around components that network stocks is serviced from stock. Where a fault is harder to find, remote diagnosis shortens it, since a walk-around on video with the panels open usually identifies the cause without waiting for a visit.

Shipping, papers and the check before crating

Export orders add steps a domestic buyer never sees. Packed dimensions, securing points and any dismantling required are settled before the machine leaves the factory, and the commercial invoice, the packing list and any certificate the destination requires are agreed at order stage, because papers that arrive incomplete hold a consignment at the port longer than the voyage took. Before crating, each machine is run: the engine is brought to temperature, the tipping circuit is cycled under load, the brakes are tested with a load, and every function is checked against the build sheet.

Which configuration to start from

The decision turns on the round rather than on the load. A tight route with frequent stops and a nearby disposal point wants one of the three machines on the smaller frame, and where the route alternates between a firm road and soft ground, the front axle clutch on the 4.Upgraded or the 7.Upgraded is the useful detail. A round that also covers distance, or one where the volume per trip matters, wants the 22.Luxury with its larger body, six tyres and air cut-off brakes.
