The RHA's TipCon exhibition at Harrogate is a highlight of the tipping industry's calendar. We look at some of the new and interesting vehicles, bodies, equipment and ancillaries on show.
• Both Foden and Iveco Ford have chosen TipCon '88 to give the first public showings of their new lightweight 6x4 chassis, using Cummins' C series engine.
Foden plans to sell about 150 of its new 3000 series this year. The mixer specification has a chassis weight of just 6,427kg. The Cummins 8.3-litre 6CT power unit, rated at 157kW (211hp) gross, is matched to the latest Eaton 6109 nine-speed synchromesh gearbox and drives through to Eaton DS410P double-drive rear axles.
Installed the six-cylinder turbocharged C series engine develops 149kW (200hp) at 2,400rpm and torque of 748Nm (552Ibft) at 1500rpm.
The Iveco Ford Cargo 2421C weighs in at 6,066kg on its shortest (4.26m) wheelbase, and claims its 345mrn deep, fine-grained titanituninobium alloy steel chassis frame is the strongest in its class. The show model is mounted on Hendrickson Norde rear rubber suspension, 140kg lighter than the standard fourspring steel suspension. The Cargo is also equipped with an exhaust brake.
GERMAN BUILT
Iveco Ford's German built Magirus 300.30 8x4, powered by the 12.76-litre twin turbocharged Deutz air-cooled veeeight engine, is now available with a faster 3.96:1 drive-axle ratio which gives it a geared speed of 1111cm/h on standard 11R 22.5 tyres. The move is designed to reduce engine revs at top speed, and give better fuel economy on motorways.
Alongside Mercedes revised 17tonner, still designated as a 1617K (which is only 63kg heavier than the old model) is a new sleeper-cabbed version of the company's 3025 eight-wheeled chassis.
ERF's E10-325ST tractive unit is powered by the latest engine option offered in the Cummins L10 range.
With air-to-air charge-cooling, Cummins has extended the power rating for its 10litre range to 242kW (325hp) with a downrated version at 224kW (300hp). Both give the same level of torque output of 1288Nm (950Ibft) at 1,300rpm with a 17% torque rise and high flat torque profile.
Air-to-air charge-cooling is also available for the eight-litre C Series engine, increasing the gross power from 157kW (211hp) to 198kW (265hp) at 2,400rpm.
Leyland Des Constructor 30.26L, powered by the Leyland 11.1-litre TL11 engine, is claimed to be the lightest 8x4 tipper chassis on the market giving a competitive edge of between 0.25 and 1.0-tonne extra payload.
The most powerful model of the company's six-vehicle show line-up is an FT 95.350.
MAN's two eight-wheel rigids feature different makes of transmission. The 30.240 has a six-cylinder in-line engine of 11.4-litre capacity, producing 177kW (237hp) at 2,200rpm and 824Nm (6081bft) of torque at 1,500rpm. It is matched to the ZF AK6-90 constant-mesh gearbox with GV90 splitter giving 12 speeds.
Fullers RTO 11613 range-change constant-mesh box offers 13-speeds and is matched to the larger 11.96-litre turbocharged and charge-cooled six-cylinder engine producing 213kW (285hp) at 182,20Orprn and torque of 1,200Nm (8841bft) at 12-1,500rpm.
Gilbraith Commercials claim that the Mecafluid automatic lubrication system is the most efficient available. It provides lubrication to key moving parts of the vehicle at regular intervals all the time it is on the road.
TIPPER CHASSIS
Renault's G260-24D 6x 4 tipper chassis is assembled built at Dunstable and runs on an Eaton Hendrickson double-drive bogie with inter-axle and cross-axle differential locks. It's MIDS 060245 turbocharged engine, developing 192kW (258hp) and 981Nm (7241bft) torque, and, B9 nine-speed synchromesh gearbox are built in France.
Perkins is to show its six-cylinder 6LXDT Gardner engine again this year. The 12.7-litre unit produces 216kW (290hp) at 1,900rpm and torque of 1240Nm (9151bft) at 1,350rpm, and is extremely light but a 231kW (310hp) version is expected soon.
The latest version of the Maclift Leader skip-loader in the 17-tonne range will handle containers with a capacity of up to 21.5m3.
York's Magnum bulk tipping semitrailer is fitted with tri-axle Tecair suspension with a front axle lift and is plated for 40-tonnes, ready to take advantage of proposed weight increases for airsuspended axles. Outrigged suspension mountings at 1,345mm centres gives in
creased roll stability in excess of 38°.
Weighing only 5,640kg the York 43.5m3 (57yd3) alloy monocoque body has folded sections, instead of extrusions, to save weight and gives a payload of 25 tonnes.
The 38.23m (50yd3) tri-axle stepframe trailer is Weightlifter Bodies' most popular product. The model shown has full BPW air-suspension with a new lightweight self-steering axle, Anchorlock spring brakes, twin king-pins, alloy wheels and a fully automatic lubrication system.
George Neville Transport Safety Systems has uprated its Delescopic trailer unit. Twin rams, operating in alternate cycles, move the front part of the body through the rear so that the 49.7m3 (65yd3) can unload in under six minutes.
Skidcheck anti-lock braking, Rubery Owen monoleaf suspension and Jost twospeed landing-legs are just some of the options available with AHP's range of two-and three-axled straight and stepframed trailers.
A Leyland Daf 7.5-tonne Roadrunner 8-12 equipped with a hydraulic truck loader, with clamshell bucket and rotator mounted behind the cab and 3m3 (4yd3) body, provides for a payload of three tonnes. The all-steel Welford double-dropside body has an outrigged underframe to minimise load height and is supplied with underfloor scissor-type tipping gear with chassis subframe.
Scania's latest 3-series trucks make their UK debut at TipCon. The Swedish truck builder is exhibiting two P83 eightleggers and a P113 4x2 tractor equipped for tipping work.
The P93 8x4s feature the updated 8.5litre DSC9-02 engine, rated at the same 205kW (275hp) as its predecessor — but with an increased peak torque of 1,125Nm (830Ibft). The P113 has the DSC11-12 engine rated at 248kW (333hp).
All three have the latest re-trimmed Scania cab with revised instrument and dash layout.
NMI's lightweight aggregate tipper is specially-designed in single-piece pressings for maximum payload and to give easy discharge of aggregates, sand, gravel and tamiacadam. The hi-tensile aluminium body, weighing just 1,040kg, is available with many options including autogate and split tailgate.
Crane Fruehauf is showing a tilted chassis to demonstrate its achievements in stability. Tests have shown a ground slope Gtability of 90 in the fully tipped position with a tri-axle stepframe steel tipper chassis fitted with Crane Fruehauf T' air suspension. The positive results are due to torsional stiffness, wide track axles and the performance of its air suspension.
Most interest however, will be centred on a CF tipping trailer based on an allalloy chassis built by fellow SESR group member Benalu.
Out of five Samson aluminium alloy tipping trailers, being exhibited by George Neville Truck Equipment, four are on full air suspension. One of these features both a rear steer and front lift-up axle, together with an on-board automatic weighing system.
Craven Tasker is showing an example of its latest Taper tri-axle bulk tipping trailer incorporating a computer-designed body and roll-resistant chassis, providing a 42m3 (55yd3) capacity and a 9.75m (32ft) internal length. Offset barn doors at the rear allow for a single, centrally fitted grain hatch.
Wilcox completes its five exhibits with the ingenious Autofloor body that provides an unloading capability where tipping is impossible, impractical or just dangerous. The 12.2m (40ft) body has a 72.6m3 (95yd3) capacity but can be operated by one man, taking only seven minutes to unload automatically.
TIPPING GEAR
Ultimate Hydraulics has an example of the new UK-made Harsh tipping gear on an 8x4 Mercedes chassis. The underfloor frame, which provides the rigidity of the system, is manufactured by Milltech, a division of Tate and Lyle, in Hull.
Tadchurch rubber suspension is now available as a factory fitment to the Leyland Daf constructor six, lightweight eightwheeler and Constructor eight range. Volvo has made the suspension available for its sixand eight-wheelers, while York Trailers have made it standard for its Quarryman range of articulated trailers.
Southworth claims the most cost effective vehicle at the show is a threeaxle Leyland Freighter equipped with its lifting mid-axle. It offers about 50% more payload than a 16-tonner, yet costs 2400 less a year to tax.
SAF's new RS 9042-series lightweight axle saves 105kg over the standard SAF tri-axle air suspension system. The singletube axle beam, designed without welded stud ends, created the need for two equal size wheel-bearings and is said to be stronger than conventional axle beams.
Kangaroo landing legs from Dayton Walther have a static capacity of 68,000kg and lifting capacity of 12,000kg per leg. While it has two speed options, the legs can be folded — once the feet have cleared the ground — to speed up loading.
Eaton's SAMT transmission, based on the Twin Splitter transmission, combines intelligent electronics with proven, easyto-service mechanical components. It has been in limited production since the end of last year.
BPW claims to produce the lightest air suspension package available, at only 424kg per axle set. This uses quarterelliptic composite springs to locate a square-section axle-beam, and lightweight hub and brake drum assemblies.
The air suspension can be specified to suit individual applications and offers a choice of ride heights between 180mm and 500mm.
SKIPLOADER
In the last few weeks a new skip-loader has been introduced by Hy-va. The Hyvalift 10, competing with the 16.26-tonne
market, has a weight of 2,000kg. This, combined with box-section cross-bearers, demountable top bar and roller jacks, allows for A-frame drawbar operation.
Hytee tippers made its name producing bore-sealer-type rams with combined oil tanks for sixand eight-wheelers. Its 65SA200 4 model for an 8x4 chassis weighs in at 506kg complete.
Telehoist claim market leadership for its CH503A Loadlugger skip-loader, in the 16/17-tonne weight bracket.
Wasey Exhaust Systems are showing a range of stainless steel vertical exhaust stacks. Its cowl exhaust for large diesel engines is said to be unique, allowing good sound attenuation and low backpressure for economical fuel consumption.
Eminox recent developments include a vertical stack for the Leyland Daf 95, the Scania '3' series and the Volvo F16.
Belco Duron's formulation of a compression-moulded, rigid, asbestos-free friction material, used in brake lining, is claimed to increase service life by as much as 50% and is kinder to drums.
On-board weighing systems have not earned a good reliability record but Precision Loads says its new electronics, unaffected by moisture penetration, provides an accuracy of ±0.5%. The twin-channel system, suitable for rigid and articulated chassis, offers fore and aft weight distribution with totalising for GVW-without adding to the vehicle weight or making structural modifications.
TRI-AXLE TYRES
Bandag's WSW wing-tread for tri-axle tyres was developed to eliminate excessive wear and shoulder damage, commonly experienced with today's wide-base super-single tyres.
Brigade is exhibiting a high-tech solution to improve reversing safety. The Backeye reversing video system gives the driver a complete view over the blind area to the rear of his vehicle, over a distance of 15 to 20m from his back bumper.
The 385/65R22.5 super-steel tyre from Semperit was specially-designed for 9tonne trailer and semi-trailer axles. It has a wide profile but is suitable for both shortand long-haul work. Wide central ribs provide high braking power, while the wide flat tread ensures a high degree of stability.
