Product Information

Diesel expands in the heat. If your fuel tank is filled to the brim and it’s a hot day, expansion of the fuel will cause it to spill on the road which is very dangerous, especially for motorcyclists. Don’t fill your fuel tank to the brim. It is also a requirement for the manufacturer’s date code to be legible on all tyres fitted to LGV tractor units and trailers over 3.5 tonnes.

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. The drawbar should not be confused with the fifth wheel coupling. The drawbar requires a trailer which either loads the drawbar lightly (for example a small boat trailer, or caravan, or the load is the weight of the coupling components only (larger trailers, usually but not always with a steerable hauled axle, front or rear). By contrast, the fifth wheel is designed to transmit a proportion of the load's weight to the hauling vehicle. Drawbar configuration is mostly seen on hydraulic modular trailer and ballast tractor combination to haul oversize loads which require special trailer and tractor. The purpose of a pre-heating device is to heat the engine in cold weather. They heat the glow plugs in the cylinders. The starter should only be operated when the indicator light goes out.

Lorry and bus tyres have codes on the tyre side walls which indicate the maximum load and the speed capability. Increased risks of punctures Older vehicles require double-declutching to change gear. On new vehicles with synchromesh gearboxes, double-declutching increases clutch wear and wastes fuel. Protective clothing It is also a requirement for the manufacturer’s date code to be legible on all tyres fitted to LGV tractor units and trailers over 3.5 tonnes.

A high-pressure fuel injector delivers fuel into the cylinders. Most diesel engines use a high-pressure fuel injector system which will deliver pressurised fuel directly into the cylinders of the engine. This system is known as a direct injection engine. When you start the engine the ignition light should go out. If it doesn’t, you have an electrical fault.Energy-saving tyres keep fuel costs down because they have a lower rolling resistance and better grip than ordinary tyres. You should consider this when replacing your tyres. 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] Vehicle operators must have an effective system in place for drivers to report vehicle defects and have them repaired properly. If you are driving along and notice that tread is coming away from one of your tyres (i.e. your tyre is delaminating), you must stop and change it. Different sized wheels If you have been issued with protective clothing by your company for use while driving, it is your responsibility to wear it.

If you see this warning light then you have a problem with your oil pressure. Continuing to drive with this light on could cause your engine to seize. If there’s not enough oil pressure the engine components won’t be lubricated. They will overheat and eventually will seize. The first thing to do before uncoupling a trailer is to apply the parking brake. After leaving the cab, apply the trailer parking brake. Always park on a firm, level surface.

Reversing too fast into the jaws can squash the towing eye meaning the pin won’t drop through. Reverse slowly until the trailer is coupled. Aggressive reversing can break or bend the funnel which directs the towing eye into the jaw. In this case, the drawbar height was too low and the approach speed too fast. The funnel couldn’t direct the drawbar into the jaw, instead breaking through the funnel. If you are driving a vehicle with a two-speed axle, this doubles the number of gears. An electrical switch actuates a mechanism in the rear axle which doubles the choice of gear ratios, which can significantly improve the performance of a heavily laden vehicle. The fifth wheel coupling is used to connect a tractor unit to a trailer. It allows articulation between the tractor and trailer.
