High-Pressure Swivel with Pressure Amplifier for Double Fluid Jet Grouting Treatment
The lifetime of a high-pressure top swivel strongly contributes to the success of a big jet grouting/soil mixing project. Depending on the RPM during drilling and the duration of each injection, swivels’ seals and shaft are doomed to fail. These failures mean that the treatment, and the entire job site, will stop for the time required to disconnect/connect the swivel (approx. 4h).

CRM’s new swivel with pressure amplifier is designed to last for the entire length of big jet grouting/soil mixing projects.
Bi-Directional Static Load Testing (BS|DSLT)

GRL Engineers  offers Bi-Directional Static Load Testing (BDSLT) with the GRL-Cell for drilled shafts, bored piles, barrettes and ACIP/CFA piles. BDSLT separates soil/rock resistance and movement data for shaft and toe while determining the magnitude of mobilized shaft and toe resistances. The GRL-Cell is a high capacity device installed within a deep foundation element to perform a bi-directional static load test. As the GRL-Cell is pressurized, it loads the foundation element in two directions. GRL-Cells sizes range from 350-3500 ton capacities and are not restricted by structural or geotechnical limit of lad frame.
Love Your Crane Again!
ICE® offers a solution to vibration dampening.

Non-inherent vibration damping mechanisms were originally developed for vibratory drivers without built-in vibration suppressors. Like ICE® vibratory hammers and extractors, most modern vibratory units are designed with onboard suppression and it is not necessary to use auxiliary dampers. However, many crane rental houses and operators may find our 2D solution comfortable by doubling up on the vibration suppression.

With keeping safety first, ICE’s unique dampener has a safe design that fully complies with ASTM wire rope sling specifications making our solution useful in additional lifting applications requiring shock or vibration isolation.
