Load Frames for Triaxial Testing

Digital MasterLoader

Designed for applications requiring multi-purpose loading systems, the HM-3000 is ideal for just about any triaxial application from road construction to high-volume commercial and educational laboratories. The HM-3000 MasterLoader provides fully-automatic test performance allowing unattended operation while controlling motor start/stop, speed selection and test data acquisition. Its modular design allows the machine to be custom configured to handle any test necessary.

You can buy the machine to handle any specific test needs and add on to its capabilities at a later time. This way you only pay for what you need, but you are never faced with an obsolete system. The HM-3000 will function as a standalone device or can be interfaced with a computer using Humboldt's HMTS software. It also provides an analog output port if you need to utilize an XYt chart recorder. The HM-3000 is specifically designed for soil testing labs conducting multiple testing operations including: UU, CU and CD triaxials, UC, CBR and LBR. With its built-in four-channel data logger, the HM-3000 can acquire data from load, strain, pore pressure and volume transducers. The data acquisition can be automated by setting trigger conditions to start and stop logging. Tests can be initiated or terminated automatically

Features include:

• Four channels with real-time data acquisition

• Backlit LCD display

• RS232 interface for computer or printer.

• Nonvolatile test data storage and instrument calibration

• Battery-backed real-time clock

• Auto conversation of instrument calibration between English or Imperial units and SI or metric units

• Test setup and selection via keypad

• Automatic triggering of test logging data

• View logged test data via the LCD display

• Logging rate as fast as 0.1 second/reading

• Humboldt HMTS, Basic, User-Defined Level software included for data acquisitionincreasing lab productivity.

Includes:

SHH04— 3/4-16 Bolt x 3-1/2 inch long

WF04— Washer for SHH04 Bolt

H-4178.2— 3/4-16 Stud x 1-1/2 inch long

H-4454.3— 3/4-16 Plug / Adapter

HM-3000.10.1— Cylinder Bracket Holder

HM-3000.10.2— Displacement Indicator Platform

HM-3000.10.3— Displacement Indicator Rod.

Digital ProLoader

The HM-2900 ProLoader has been specifically designed to handle triaxial testing applications, including: UU, CU and CD triaxials, UC. From educational institutions and consulting firms to high-volume commercial labs and construction projects, the ProLoader can handle any application with ease. With its 3,000 lb. load capacity, the HM-2900 can easily handle all basic triaxial tests with ease.

The HM-2900 ProLoader provides fully-automatic test performance allowing unattended operation while controlling motor start/stop, speed selection and test data acquisition. Its modular design allows the machine to be custom configured to handle any test necessary. So, you can purchase the machine set up to handle a specific test need now, and add on to its capabilities later to handle additional tests. This way you only pay for what you need, but you are never faced with an obsolete system.

Features include:

• Four channels with real-time data acquisition

• Backlit LCD display

• RS232 interface for computer or printer

• Nonvolatile test data and instrument calibration storage

• Battery-backed real-time clock

• Auto conversation of instrument calibration between English or Imperial units and SI or metric units

• Test setup and selection via keypad

• Automatic triggering of test logging data

• View logged test data via the LCD display

• Logging rate as fast as 0.1 second/reading

• Humboldt HMTS, Basic, User-Defined Level software included for data acquisition

Multi-Speed Load Frame

The HM-2800 Multi-Speed Load Frame is designed for those who want a high-quality but simple, multi-purpose load frame without built-in data acquisition capabilities. The HM-2800 is ideal for triaxial applications where the operator either is not concerned with data acquisition; or, already has an existing data acquisition system or plans on constructing one. With its digital display, the HM-2800 also provides the operator the ability to select any speed with three decimal accuracy within its speed range.

The HM-2800 features a quiet, direct drive DC motor that provides a loading speed range from .008 to 1.999 in/min., controlled through the use of edit keys and a digital display. It also incorporates a separate, dedicated control to accommodate 2.00 in/min. for use in Marshall and TSR Testing. The controls also accommodate a rapid travel speed of 2.25 in/min for moving the platen into position quickly.

Features include:

• 10" platen provides roomy, stable base for test equipment

• Backlit LCD display

• Test speeds adjustable from .008 to 1.999 in/min. via keypad

• User selectable unit change between U.S. Standard and Metric from keypad

Includes:

SHH04—3/4-16 Bolt x 3-1/2 inch long

WF04—Washer for SHH04 Bolt

Multi-Speed Load Frame, 115V 60Hz— HM-2800

Multi-Speed Load Frame, 220 50/60Hz— HM-2800.4F
