Frequently Asked Questions About HC42
Common questions about HC42 specifications, applications, and selection criteria.
What is the effective depth of HC42?
The HC42 achieves effective compaction depths of 1.2 to 2.5 meters, depending on soil type, moisture content, and number of blows per point. It is classified as a shallow to medium-depth RIC machine.
What carrier machines work with HC42?
The HC42 is designed for 5-6 ton wheel loaders such as VOLVO L120GZ and CAT 950L, and can also be mounted on 30-40 ton excavators as an alternative configuration.
What projects is HC42 best suited for?
HC42 excels in bridge abutment backfill, culvert side treatment, confined zone compaction, road widening transitions, and general municipal infrastructure projects with limited space.
How does HC42 compare to HC36?
HC42 offers 17% higher impact energy (42kJ vs 36kJ) with the same carrier requirements, making it the better choice when slightly deeper or denser compaction is needed.
What is the difference between loader-mounted and excavator-mounted?
Loader-mounted HC42 provides better mobility and is ideal for moving between multiple work zones. Excavator-mounted offers more precise positioning control for vertical access work.
Does HC42 require special hydraulic systems?
No. HC42 operates at 16 MPa and ~160 L/min, which are standard specifications for compatible wheel loaders and excavators, requiring no hydraulic system modifications.
