New Hamm HC-series rollers can crush and compact in single step

The new Hamm HC 250 C VC (Tier 3) and HC 250i C VC (EU Stage V/EPA Tier 4f) compactors are able to crush and compact mixed soils, stones such as basalt and granite, and other construction materials with comparable pressure resistance in a single step. The Tier 3 model will be available later this year.

Featuring Deutz engines and reinforced components around the front frame, three-point articulation and the underbody, the new compactors are well-equipped for tough applications. The initial ‘VC’ in the model name indicates vibration crusher, while the separate ‘C’ symbolises a reinforced drum drive, which is capable of inclines of up to 60%.

These 25-t machines come with heavy-duty tyres for rocky terrain and the Easy Drive operating concept. In the operator cab, the seat has an extended backrest for greater comfort and an air-sprung seat can be selected as an option.

A highlight of the new VC compactors is the newly designed tool holder system. This is compatible with round-shank cutting tools for stone, as well as wear-resistant heavy-duty cutting tools with carbide tips and hard facing for abrasive stone or hard stone.

The configuration of the tool holder system and the way the tool inserts attach have been designed to ensure assembly and removal are quick and easy with no need for specialist tools, thus keeping maintenance and servicing costs low. The existing machines (H 25i VC/3625 VC) can also be fitted with the new tool holder system by switching the drum. Transport rings are available for easy transport.

The new VC compactors are suitable for a wide range of applications. Besides the customary crushing and compacting of geological material to create a stable substrate, the machines are also deployed to level rubble in landfill sites. In addition, they can be used for road planning works in tunnel building and surface mining sectors, or to pre-crush and loosen stone.
