S5831 50kN and 100kN MULTI-LOADERS


The Multi-Loader series of economy load frames can be used to perform CBR, soil cement, unconfined compression, triaxial and Marshall tests. With an adjustable rate of strain between 0.025 to 12.7mm (0.001 and 0.5 inch) per minute, S5830, S5830A and S5831 are recommended for unconfined compression, CBR, soil cement and triaxial testing (with the proper accessories) if the rate of strain is adequate. S5830A includes a 10,000 lbf or 50kN load cell and built-in digital display with peak hold feature and computer output for data acquisition. Load is displayed digitally to 1 lbf or 10N on SI versions.

Two table models 100kN (22,000 lbf) Multi-Loaders are available (S5831 and S5841). Both include 100kN or 20,000 lbf load cell with built-in digital display of load.

Model S5831 and S5841 are the only moderately priced, variable speed load frames capable of testing up to a capacity of 22,000 lbf (100kN) now being offered.

By adding an EDDI and S2016 Data Acquisition Software any load cell model Multi-Loader or triaxial load frame can be converted to full automatic data acquisition.

All S5840 series Multi-Loaders (S5840 , S5840A and S5841) leave our production facility with 3 precalibrated speeds in addition to the continuously variable range. The precalibrated speeds are 1mm, 0.05" and 2" per minute. Other selected speeds can be set up by us or by the user using a simple procedure.

S5840, S5840A and S5841 have been developed for laboratories needing a machine capable of testing soil, soil cement and asphalt (Marshall) specimens. With 50kN (11,000lbf) and 100kN (22,000 lbf) load capacity and adjustable 0.5 to 51mm (0.02 to 2") per minute platen speed, these machines are ideal for UK and USA CBR testing performed respectively at 1mm and 0.05 inch per minute, Marshall at 2" or 50mm/minute as well as unconfined compression and triaxial (with the proper accessories). A 50 or 100kN (11,000 or 22,000 lbf) load cell with digital display mounted in chassis reading to 10N or 1 lbf if specified is standard with S5840 and S5841 respectively. Display has peak hold feature showing load at failure and an output for data acquisition or recording. S5840A is identical to S5840, but has a 10,000 lbf or SI equivalent proving ring with calibration curve in place of the load cell for added economy. A 6,000 lbf proving ring can be supplied if specified. With its extended speed range, unconfined and triaxial testing are now convenient to perform.

The Multi-Loader sloping chassis has a return-stop-test control, digital speed control dial, upper and lower limit switches, on-off switch and adjustable upper crossbar. Total travel is 2.5". Width between columns is 12" and maximum opening between platen and crossbar is 35". Speed is accurately maintained by armature feedback. An 8" (203mm) diameter lower platen with concentric circles is supplied with all Multi-Loaders.

Gear box is cast, precision machined, high strength aluminum alloy. This eliminates deflection of individual components sometimes sandwiched together on other make load frames. Drive spindle travels through a machined sleeve totally eliminating side movement. An easily disassembled, enameled, heavy gauge chassis contains the gear box and drive mechanism. Tie rods are threaded giving necessary vertical adjustment. Top of chassis has 10" (254mm) wide free space-enough room to hold a plotter or dot matrix printer. Chassis is finished in blue and gray, measures 29x18x10" (737x457x254mm). Overall height is 54" (1,372mm). Standard voltage requirements on 50kN models are 115VAC. For 230VAC, specify -3 after catalog number. 100kN models come in 230VAC only.

Multi-Loader Accessories

These accessories are also suitable for use with S5770 series load frames. S5843 may also be used with S5760 load frame.

S5833 Unconfined Compression Set for S5830
ASTM D2166; AASHTO T208

Set consists of a 1,500 lbf double proving ring (or 500 lbf double ring if desired), 2" (50mm) travel dial indicator, 2 plastic discs, strain attachments and upper platen. If specimen is more than 5" in length, a 2" travel strain dial is needed. Please request quotation.

S5834 CBR Test Set for S5830
ASTM D1883; AASHTO T193

This set when used with S5830 enables test to be performed in accordance with ASTM and AASHTO specifications. A 6,000 or 10,000 lbf proving ring with 7.5" penetration piston, 1" travel dial indicator and indicator holding bracket are included.

S2016 Unconfined Data Acquisition System

This system can be used with any load frame having a load cell with compatible digital display and EDDI. Consisting of several components including a connecting cable and adapter, this system permits input of control parameters, specimen and project data as well as real time display of load and deformation data in graphic and digital form and data storage in ASCII format.

S2020 Unconfined Compression Software

This data acquisition program provides real time display and post processing of test data. Either SI or British units may be selected for default use. Graphical data may be displayed to the computer screen or directed to a hardcopy device which are supported at maximum resolution in black and white or color, as well as most popular dot matrix and color printers. Plots may also be output in a form which is readable by most word processors negating need to cut and paste in reports. A free demo disk is available upon request. Minimum computer requirements can be found in description of S2015.
