Customers have found the Model 7730DT to be highly productive in both shallow and deep sampling venues. The stronger, wider undercarriage allows this machine to be used on concrete or pavement, and enables the machine to readily negotiate in tight, confining work areas and on offroad, rugged terrain. And with the variety of options available, it's uniquely flexible to switch from environmental to geotechnical work with little time and effort. |

|
|
|
|
A
wireless remote control transmitter provides precise control of engine
functions as well as track movement. |
|
|
An
easy-to-use, well-planned control panel is located close to probing
or augering activities to assist in smooth field operation. A 12-volt
outlet on the side of the control panel can power various accessories
or accommodate a 110-volt inverter for equipment such as the Slug
Test Kit, Electrical
Conductivity Logging System, or a peristaltic pump. |
|
|
Four swing-open doors on the top, side and rear allow easy access for daily maintenance to the engine and hydraulic components. |
|
|
Work
table, sample preparation area, tool storage, machine vise, and Hydraulic
Liner Extruder are standard equipment on the Model 7730DT. |
|
|
Convenient onboard water storage and high pressure washer system for tool decontamination. |
|
|
The
heart and soul of every Geoprobe® machine is the GH62 Hammer,
which is standard equipment on the 7730DT machine. The GH62 Hammer
was designed specifically for soil probing applications and hits at
over 1,900 blows per minute and delivers forces greater than 80,000
pounds per blow to the top of the probe rod. The GH62 Hammer has bi-directional
rotation and can break through concrete in minutes. Use it with breaker
bits or coring bits to make a clear path for sampling. |
|
The Hydraulic Liner Extruder comes standard equipment on the Model 7730DT. |
|
The machine loads easily on a trailer and can be pulled by heavy-duty trucks. |
|
|
Optional
Equipment -- DH100
Automatic Drop Hammer:
Adds to the versatility of the machine by allowing geotechnical standard
penetration tests. Uses auxiliary hydraulics on machine for repeatable
and accurate blow count results. |
|
|
Optional
Equipment -- Overhead Mast and Hydraulic Winch:
Designed to relieve operator fatigue associated with heavy lifting
of large tooling and augers. Also helpful for tripping dual tube samplers.
Lifting capacity is approximately 3,000 pounds with a line capacity
up to 65 fpm. Individual components include a 12-foot overhead mast
with swivel tophead, hydraulic winch with 30-feet of wire cable, swivel
hook, and quick disconnect hydraulic lines.
