New Ingersoll Rand CB Breakers Allow for Bucket, Tamper

Ingersoll Rand Attachments has introduced a lineup of six breakers, which attach to carriers up to 11 tons (10 t).

The Ingersoll Rand breakers expand the scope of work a breaker can accomplish. Standard breaker tasks such as trenching, demolition, and cutting, as well as compaction and excavation, can be completed with the same attachment. Two accessories — a bucket and a tamper — can be mounted onto the breaker without altering hydraulic connections. Using these accessories allows one operator, one carrier, and one attachment to accomplish multiple tasks for maximum productivity.

The breakers not only break up materials, but with the addition of a clip-on bucket, they can be used to clear away debris. The breakers also can be converted into a hydraulic tamper — without altering hydraulic connections — and used to compact the aggregate.

The energy chamber features a diaphragm design that holds its charge without requiring regular nitrogen refills. This results in constant impact energy on the work site.

Maintenance is easy with these breakers because they have fewer moving parts than other breakers and no tie rods to remove. If needed, the breakers can quickly be disassembled without special tools, reducing maintenance time and cost. The wear items are field-replaceable so the breakers can function with less downtime.

The compact profile of the Ingersoll Rand breakers also makes them easier to maneuver in hard-to-reach work areas, according to the manufacturer.

A pin-and-retaining ring system holds the single, field-replaceable bushing and tool in place while protecting the grease fitting. The retaining ring can be easily removed with or without the multipurpose tool included with the breakers. The tool also serves as a gauge for all wear components.

An automatic pressure regulator ensures that the breakers operate at maximum performance on all carriers, regardless of flow variations. Upper and lower shock absorbers isolate the breaker from the carriage, reducing noise and vibrations transferred to the carrier and the operator.
