Grease is not necessarily harmful, argues Andy Walton, technical manager at Marcar Steel and Engineering, which distributes V.Orlandi drawbar equipment in the UK. It all depends on how much is used. “Orlandi couplings have a grease nipple and all you need to do is give them a shot of grease once a year,” he says. Turning to the couplings themselves, V.Orlandi is now supplying them with a cast steel rather than a cast iron jaw. “Cast steel is standard on the 57mm coupling and optional on the 50mm model,” says Walton. “It’s harder to break than cast iron.”

With the exception of the partners mentioned above, we will under no circumstances pass on your personal data to other companies or institutions, except if we are legally obliged to do so (for example, if the police requires it in the case of suspected crime). To help ensure that the prime mover and trailer are properly coupled together, VBG has introduced an air-operated coupling with red and green lights that complement the red and green lights in the cab. If the green light is illuminated, then all is well. If the red light has come on, however, then the driver should stop immediately and investigate why.It uses a crosshair which enables the driver to aim for the towing eye when reversing (pictured). Green guiding lines indicate the optimum height range of the vehicle in relation to the eye. UK operators of drawbar combinations include animal feed supplier Harbro. It has acquired an IVECO S-Way 6x2 rigid equipped with a 7.9m curtainsider body and fitted with a VBG coupling which it uses to haul a tri-axle curtainsider trailer. When deliveries have to be made to farms that are difficult to access, the driver uncouples the trailer and takes the feed in using the rigid. It has a rear-steer third axle to aid manoeuvrability.

Agricultural equipment is hauled by a tractor-mounted drawbar. Specialist agricultural tools such as ploughs are attached to specialist drawbars which have functions in addition to transmitting tractive force. This was partly made redundant with Ferguson's development of the three-point linkage in his famous TE20. Turn the steering wheels slightly towards the kerb: if the vehicle rolls, it will steer into the kerb and stop. In foggy weather you should avoid parking on the road; if you must park on the road, leave your parking lights on. Parking on a hill If you’re stopping overnight in a lorry park, it’s a good idea to park with the rear doors close to another lorry to keep the load safe. Always park in a secure, well-lit, reputable lorry park or designated parking area if possible.Leave the vehicle in gear: if the parking brake fails, the engine should stop the wheels turning. (This only applies to an HGV with manual gears.) On light vehicles, the most common coupling is an A-frame drawbar coupled to a 1 7/8 inch or 50mm tow ball. These drawbars transmit around 10% of the gross trailer weight through the coupling.

convenient – you’re more likely to cause damage, either to your vehicle or another vehicle, if it’s an awkward spot A drawbar is a solid coupling between a hauling vehicle and its hauled load. Drawbars are in common use with rail transport, road trailers, both large and small, industrial and recreational, and with agricultural equipment. Before you leave your vehicle, make sure the engine has stopped, the ignition system is switched off and the parking brake is on. Bear in mind that if a drawbar combination is involved in an accident, and the cause appears to be a fault in the link between the prime mover and the trailer, then the enforcement authorities will want to see evidence that inspection and maintenance procedures were adhered to. The operator will be in hot water if no such evidence can be produced.The direction of haulage may be push or pull, though pushing tends to be for a pair of ballast tractors working together, one pulling and the other pushing an exceptional load on a specialist trailer. The most common drawbar configuration for heavy vehicles is an A-frame drawbar at the front of a full trailer that connects to a tow coupling on a hauling vehicle [1] Unfortunately goods vehicles and trailers are often targeted by thieves. To help keep your vehicle secure Just remember that when you are reversing up to a drawbar trailer, it’s gently does it,” says Walton. “Force is the enemy of drawbar couplings.”

When you’re parking on a hill, you can use the wheels and the engine to make sure your HGV cannot roll away in case the parking brake fails. If your vehicle has air suspension, remember that it may move when you park it or when you start it: make sure you’re not parked too close to other vehicles, buildings, street furniture, etc, which the vehicle body could collide with if it moves.Our web shop displays general advertisements. We do not keep any personal data, so we do not know if you like them. Howard Ostle does not mince his words. “We’re terrible at drawbar coupling maintenance in Britain,” he states; and as UK sales and marketing manager at VBG Group Sales, he has seen the consequences of a lax approach taken by too many operators. Use plenty of lubricant instead,” Ostle advises. “Oil is a cheap mechanic, and if you lubricate a coupling, then you won’t get a problem.” Other brands are heading down the cast steel route, too – but no matter whether cast steel or cast iron is involved, drawbar couplings have to be treated with consideration.
