The APR 49/20 Reversible Compaction Vibratory Plates are a powerful and maneuverable choice for construction tasks. With an 8.2 kw engine, it offers excellent climbing and compaction capabilities, performing well on grades up to 30%. It's heavier than most vibratory plates, except the APR 59/20. The working width of 450 mm can be extended by 75 mm or 150 mm. The durable engine hood provides easy access for servicing. It features an operator - friendly, vibration - cushioned and foldable guide handle for easy transport. The smooth variable hydrostatic forward and reverse motion allows for “on - the - spot” vibration. It has ergonomic handling, a maintenance - friendly two - shaft exciter unit with long service intervals, a wear - resistant and self - cleaning base plate, a well - protected robust centrifugal clutch with a wear - resistant V belt, and a powerful petrol or diesel engine. Optional features include a rubber mat for asphalt paver applications, an hour meter, and an electric starter. The machine weighs 391 kg, and the weight varies with different extension plates. It's equipped with a Hatz 1B40 diesel engine with an output of 6.6 kW / 8.8 HP at 2900 RPM. The maximum vibration frequency is 65 Hz, and the maximum centrifugal force is 49 kN. The working surface area per hour can be increased with extension plates. It has a speed of 35 m/min, a 5 - liter fuel tank, a gradeability of 30%, and a maximum incline of 25° to all sides.
Using the APR 49/20 Reversible Compaction Vibratory Plates is straightforward. First, make sure the engine is fueled up with the right type of fuel, which is diesel in this case. Check the fuel tank level before starting. To start the engine, you can use the electric starter if it's equipped. Once the engine is running, you can use the smooth variable hydrostatic controls to move the plate forward or backward. You can also use the “on - the - spot” vibration feature for better compaction. When working on slopes, remember that it can handle grades up to 30%. If you need a wider working area, you can attach the extension plates. When transporting the machine, fold the guide handle for easy loading and unloading. As for maintenance, the two - shaft exciter unit has long service intervals, but it's still a good idea to check it regularly. The base plate is wear - resistant and self - cleaning, but you should still clean it after heavy use. The centrifugal clutch and V belt are well - protected, but inspect them for wear. Keep the engine in good condition by following the manufacturer's maintenance schedule, like changing the oil and air filter at the recommended intervals. Also, check the fuel tank for any leaks and keep it clean.
