The models of the GROSS electric rammers are the result of studying the needs of customers and the extensive work of the company's design department. Along with excellent technical characteristics, the GROSS TR70E1/E3 and GROSS TR90E1/E3 electric rammers have the important advantage of increased protection for equipment and the operator.

A new feature, which is still found on the Russian market only in expensive models from Western manufacturers, has been successfully used in GROSS vibration rammers for more than four years – automatic protective shutdown of the rammer when the operator releases the handle. The function is reliable because it uses a magnetic contactless switch (there is no mechanical switch that could fail as it wears out) and solid-state relays controlled by a voltage of 220V (380V), which make it suitable for use in case of strong vibration. The relays are housed in an aluminum alloy box, which promotes better heat dissipation and prevents them from overheating.

The power lever on the handle of the rammer is positioned so that it is easy to hold it clamped for a long period of time during operation. The design of the switch's mechanical pull is reliable and simple.

Included: protective headphones and a mask.
