EV-RM85 Tamping Rammer
15kN Tamping Rammer for Foundation & Heavy Civil Construction
Product Introduction
Construction projects involving structural foundations, retaining walls, bridge approaches, and deep trench backfilling require greater compaction force than standard lightweight rammers can provide. Higher soil density is essential for improving load-bearing capacity and reducing future settlement. The EVOX EV-RM85 is engineered to meet these demanding requirements by delivering stronger impact energy and excellent durability for intensive construction work. As a 15kN Tamping Rammer, it is designed for contractors who require dependable compaction performance on large civil engineering and infrastructure projects.
Powered by a reliable 4.0HP (3.1kW) gasoline engine, the EV-RM85 generates up to 15kN of impact force with a 40–80mm jumping stroke, allowing deeper soil penetration and efficient compaction of cohesive materials. Its reinforced frame, heavy-duty bellows system, and wear-resistant tamping shoe are built to withstand continuous operation under demanding jobsite conditions. It is also available with comprehensive OEM and ODM customization for construction equipment distributors worldwide.

Frequently Asked Questions
Q: When should a 15kN rammer be selected instead of a lighter model?
A: A 15kN machine is recommended for projects requiring greater compaction depth, higher soil density, and stronger support beneath structural foundations or heavy-duty infrastructure.
Q: Which soil conditions are most suitable for the EV-RM85?
A: The machine performs particularly well on cohesive soils, clay, mixed backfill materials, and compacted foundation layers where higher impact energy improves consolidation.
Q: Why does a longer jumping stroke improve compaction performance?
A: The 40–80mm stroke enables deeper energy transfer into the soil, helping achieve better compaction results in thicker fill layers.
Q: How does the reinforced frame benefit contractors?
A: The strengthened structure improves machine durability during continuous operation, making it suitable for demanding construction projects and rental applications.
Q: Are different engine configurations available?
A: Yes. EVOX can provide alternative engine options, customized branding, and product configurations according to customer requirements.
Q: What technical services does EVOX provide?
A: EVOX supports distributors with spare parts, engineering consultation, technical documentation, product training, and long-term after-sales assistance.
