• There were a number of surprises among Jack Allen (Motor Bodies)'s El. lm display at the Institute of Waste Management exhibition, including the company's automated side-loading Colectomatic.
The American design, which is said to be able to serve over 1,000 homes daily on one-man operation, uses a side-mounted video camera system with a monitor beside the control panel in the cab. It loads into the front of a 20.6m3 body, uses a short 1.2m stroke packer box and discharges by tipping, helped by the packer unit.
Mounted on a 6x4 Britannia chassis, the prototype has a 12,120kg unladen weight and with an Allison automatic gearbox will retail for about .295,500.
Jack Allen also showed a 38.2m3 compaction-bodied semi-trailer. A self-standing unit with its own 74.6kW sixcylinder Lister diesel engine to power the hydraulic pump, it can be moved between sites by any suitable artic. Its rear arms will raise up to 5.0 tonnes, and its hopper will take up to 2.3e — hence its name, "Mighty Bite".
Norba's latest Linea 3 range of refuse trucks comprises 14.4, 16.4 and 18.2m3 models for three-axled chassis, with payloads from &75 to 12.5 tonnes. The new design uses a modular body system with a channelled frame covered by plastic side panelling. It now has a three-stage packing mechanism with a 6:1 compression facility.
Bolt-on bin lifts are available to suit most applications, all giving 165° angle of discharge into the hopper, which also has self-lubricating nylon slide blocks. Norba has 50 Linea RL3s on order, not counting the one exhibited in Darlington Council livery. It expects its sales of refuse vehicles to reach 350 this year, an increase of 13% over 1988.
Whale Tankers showed its multi-functional KiloWhale Combination, which can be used as a vacuum tanker, jetter or deep lift pneumatic conveyor. It uses a liquid ring exhauster, which absorbs up to 63kW in generating an airflow of 28n3/rnin and an airspeed of over 1,554m/min through 152mm-diameter pipes to handle heavy viscuous sludge, even through its swivelling, extending boom. Where depths are excessive, vacuum handling is replaced by pneumatic conveyancing.
When jetting, a gearboxdriven Pratissoli pump uses up to 60kW to delivery 245lit-min at pressures up to 138bar. Boom movements are control led from a wanderlead switch box, while engine speed, pump, exhauster, hose reels and main valves are controlled from a console at the rear.
Tipper body manufacturer ACCO (Motor Bodies) of Wednesfield unveiled its new Delta combined tipping hook arm demountable system for chassis up to 7.5 tonnes. Hydraulic power comes from an engine-driven pump, and the folding underframe is operated by a centrally-mounted ram.
Offloading the demount body is via the hooked arm, while hydraulic cross-locks hold the frame together to allow the system to tip. It all adds 320kg to the weight of a Transit chassis and costs .24,000, Bodies retail at about £1,000, depending on the type.
Equipment to ease the interchange of bodies between road and rail was exhibited for the first time by Shrewsbury-based Multilift.
Based on its military system, the demountable SRTE (Simple Rail Transfer Equipment) can be used with a suitably modified Hooklift vehicle. It is powered by the same hydraulic system and can shift 20-tonne ISO containers up to 2.74m high, loading from the left or r_ight.
