Low-flow compactor series for excavators

Engcon recently announced it will launch a series of entirely new low-flow compactors that can be powered by tiltrotators in 2019. According to Engcon, this will extend the area of use considerably and make excavators both more efficient and safer.

Engcon has manufactured compactors for excavators since the 1990s, but the problem hitherto was their demand for such a high hydraulic flow that they could not be connected directly to the tiltrotator’s extra outlet. This meant the compactors could not be rotated freely. Engcon has solved this problem with the newly developed series of low-flow compactors.

“We know that the compactor/excavator combination is ideal, as it means a major improvement in the work environment for ground workers, who must otherwise walk and control compactors down in the excavation, whose nature can vary a great deal,” said Johan Johansson, designer and project manager for Engcon’s new compactor series.

Engcon is introducing three models – the PC3500, the PC6000 and the PC9500 – where PC stands for plate compactor and the numerals indicate the compaction force in kg for each of the compactors.

The PC3500 will compact with approximately 7,715 lbs-force, the PC6000 will compact with approximately 13,228 lbf and the PC9500 will compact with approximately 20,944 lbf.

“Another major advantage when using compactors on excavators is the marked improvement in safety for ground workers. For example, when compacting in deep excavations there is a great risk that the vibrations from the compactor will cause a collapse, burying people under volumes of heavy soil,” declared Johansson.

In addition to the improved working environment and reduced risk of personal injury, Engcon’s compactors can be used on inclines where conventional soil compaction with rollers or hand-operated compactors is not possible. This includes everything from ordinary road embankments to compaction around bridge supports, erosion protection along watercourses and more.

Sorting grapples: Stronger, better suited

They’ve also introduced a new generation of rock and sorting grapples. The new grapples were displayed at Bauma, the world’s leading trade fair for construction machinery, held in Munich from April 8 – 14.

Fifteen years have passed since Engcon launched the SK stone and sorting grabs, and over the years they have become increasingly common accessories that make excavators even more useful and flexible. But because tiltrotators have developed a great deal in 15 years and excavators are now more powerful, Engcon is adapting the grabs to meet today’s needs by strengthening them and making them more suitable as accessories.

“In addition to strengthening the new grabs to make them more suitable for new generation tiltrotators and excavators, we will make sure they are more suitable as accessories,” said Johan Johansson, designer at Engcon Group.

Johansson reported that the grab arms will be closer together to more easily retain small items that otherwise would run through the grabs. They will also come ready for the installation of side plates. This will make converting a stone and sorting grab into a clamshell bucket quick and easy.

As before, the attachment points will be bolted on and ready for Engcon’s EC-Oil connector. All joints will be fitted with expander bolts to minimize play, cutters will be bolted-on for simple replacement and ready for mounting bucket teeth. The new grabs will be available in six sizes suitable for excavators from 1.5 up to 33 metric tons.

The SG12 will be the first model in the new grab series for release; it has a grab area of 3.6 ft² and is suitable for excavators in the 6 – 12 metric ton class. Production is planned to begin in the summer of 2019.
