Video: Geoprobe® Model 54LT

Standard Doorways Don’t Stand in the Way

Drillers seeking a rugged, compact mini drill rig to slide between standard 36-inch doorways choose the 54LT. This mini drill rig is narrow enough to get into confined, enclosed places yet sturdy enough to track on tough terrain. Additional advantages of the 54LT mini drill rig include:

  • Lateral movement to offset probe without moving the mini drill rig
  • Probe cylinder speed control valve for consistent CPT push at 2 cm/second
  • Optional low clearance cylinder to handle 8-foot ceilings

Owners appreciate their ability to handle indoor and outdoor jobs with their 54LT mini drill rig.

"I was really impressed at how the 54LT was able to advance the probe through large, gravelly materials. You always sacrifice power for a smaller-sized rig, but the samples we recovered speak for themselves."

Tooling & Accessories

DT22 Soil Sampling System

Video: DT22 Soil Sampling System Overview

The Geoprobe® DT22 Soil Sampling System is a direct push system for collecting continuous core samples of unconsolidated materials from within a sealed casing of Geoprobe® 2.25- inch outside diameter probe rods. Samples are collected and retrieved within a liner that is threaded onto the leading end of a string of Geoprobe® 1.25-inch OD light-weight center rods and are inserted to the bottom of the outer casing.

SP22 Groundwater Sampler

The Screen Point 22 (SP22) Groundwater Sampler from Geoprobe Systems® was designed to keep the screen away from all percussive energy while the sampler is lowered downhole, thus extending the life of the screen. The SP22 can be used alone as a groundwater grab sampler or groundwater profiling tool, or with the DT22 Soil Sampling System. The screens can be deployed using either 1.25-inch Lightweight Center Rods or PVC riser. Designed for tough probing conditions, the screen head on the fully retrievable sampler adapts to either a stainless steel or PVC screen.

MC5 Core Sampler Soil Sampling System (LWCR)

Our MC5 Soil Sampling System is a single tube, discrete or continuous system with unmatched durability. MC5 Light Weight Center Rod Soil Sampling System. The MC5 1.25-inch Center Rod System was designed for the absolute worst of the worst direct push probing conditions. “These are conditions that we normally do not recommend probing in,” according to Mike Carlin, Project Engineer, “so we developed the toughest soil sampling system in the direct push industry ... it’s a brute!” Macro-Core® is a registered trademark of Kejr, Inc., Salina, KS.
