How to operate a tipper

 Free-Report-Banner_01



Taking shortcuts and not following established safe operating procedures can have serious consequences when tipping a tipper semitrailer. Every operator of such equipment should bear in mind the following advice to minimise the risks and ensure the safety of the operator and other personnel, and it can also prevent serious damage and injuries.
Following some simple rules of proper use starts with the loading operation: The trailer should not be loaded if it is disconnected from the tractor; otherwise the trailer may overturn. The load should be evenly distributed in the tipper body also to reduce the risk or the semitrailer overturning while driving or subsequent unloading.
Before starting the unloading, the semitrailer and the tractor should be placed on firm, level ground and both vehicles should be aligned. It is unacceptable to unload while the semitrailer is positioned at an angle to the tractor. Before starting to tip it must be checked if when fully lifted it will be well clear of other objects, e.g., overhead power lines, trees, etc. Before lifting the body, the semitrailer pneumatic suspension should also be lowered.
The unloading should be performed in a continuous and fluent manner, without unnecessary increase in the engine RPM. It must be checked if material sliding off the tipper floor is not blocked at the end of the tipper body as this might lead to the overturning of the vehicle. If the load becomes blocked while the body is lifted, it is forbidden to jerk the tipper body or drive in the lifted position. Such practices can very often cause serious accidents. It should be strongly emphasised that the cylinder is designed to lift and lower the tipper body and is therefore not contributing to the vehicle’s stability. During the tipper operation a cylinder should not be subjected to the effect of lateral forces.
It is prohibited, for safety reasons, to go under a lifted, unsupported tipper body.
A tipping cylinder should not remain extended for longer than 30 minutes. After unloading the trailer, the cylinder should be lowered to the very end and after one minute the tipping control lever should be shifted to the neutral position. Care for proper condition of the hydraulic system will guarantee a long, trouble-free operation of the tipper system. It is not recommended to allow unauthorised personnel to work on the hydraulic system, especially any adjustments to the pressure settings. Every cylinder should be operated with correct pressure which does not exceed the maximum allowed working pressure determined by the manufacturer. This value is specified on the type plate of every Hyva cylinder. It is also essential to check regularly the oil level in the hydraulic system, the oil tank should contain enough oil to allow maximum extension of the cylinder. The type of oil should be properly selected for the intended use and climate. The oil should be changed once a year. Daily inspection should include checking the condition of the hydraulic hose connecting the cylinder with the hydraulic system, verifying the correct connection of quick release couplings, the condition of brackets fixing the cylinder, lubricating the pivot points and tightening the bolts fixing the brackets.
