Call MNM Scales at (832) 290-3120 or email mnmscales@yahoo.com for current availability, application questions, and help confirming whether this 15,000 lb x 2 lb system is the right configuration for your force-measurement job.
The MNM MS720-15K 15,000 lb x 2 lb S-type crane scale is a calibrated tension/compression force-measurement package built around an alloy-steel S-beam load cell, digital indicator, rechargeable power and two eye bolts. MNM lists the system as calibrated and ready to use, with Peak Hold, lb/kg selection, RS-232 output and a 15,000 lb capacity with 2 lb displayed increments. That combination makes it relevant to buyers searching for a 15k load cell scale, heavy tension scale, pull-force meter, hoist test scale, cable tension test system or portable industrial force display.
Verified MS720-15K specifications
MNM’s live listing identifies 15,000 lb capacity and 2 lb accuracy/readability, Peak Hold, an alloy-steel S-type load cell, digital indicator, rechargeable battery and power supply, and two eye bolts. The indicator listing describes a plastic enclosure, mounting bracket, a 1-inch LED or LCD backlit display, selectable lb/kg units, zero, gross, net, accumulation, printing, counting, check weighing and auto-hold functions, RS-232 output, gravity adjustment and support for up to eight 350-ohm load cells. The listing also states 6000e, maximum 30,000d and 0.3 µV/e indicator resolution. Those indicator figures describe the readout electronics; they should not be interpreted as a guarantee that every mechanical installation will achieve the same usable force resolution under vibration, side loading or poor fixture geometry.
Why 15,000 lb x 2 lb matters
A 2 lb display increment is a practical compromise for high-force work where the operator needs much finer information than a coarse 5 or 10 lb crane display but does not need the extreme sensitivity of a low-capacity laboratory force transducer. It is especially useful when comparing pulls, checking repeatability between fixtures, documenting tension changes or identifying a meaningful force peak. The 15,000 lb capacity also provides headroom for jobs that are too large for 5,000 or 10,000 lb systems. Capacity headroom is not a substitute for proper engineering: shock loads, dynamic lifting and side loads can create forces well above a nominal static reading, so the complete fixture must be rated for the application.
Typical applications and users
Common search-intent applications include cable and wire-rope tension checks, winch and recovery pull measurement, controlled hoist proof testing, actuator and hydraulic-cylinder force measurement, fabrication fixture verification, heavy spring testing, machine setup, rigging research and industrial quality-control test stands. Users may include maintenance departments, fabrication shops, vehicle and recovery specialists, manufacturers, test technicians and scale-service companies. For suspended applications, use rated hardware and a controlled setup designed for force measurement; a load cell system is not itself a lifting-safety certification for the entire rig.
Setup and installation
Install the S-beam so the applied force follows the intended load axis. Avoid using the body as a structural stop and avoid side pull, twisting or bending moments. Inspect the eye bolts and mating hardware, center the load, secure the indicator where the display can be read safely, and route the cable so it cannot be pinched or used as a strain member. Before applying a large load, power the indicator, allow the system to stabilize, verify a clean zero, apply a small known load and confirm that the reading moves in the expected direction. If the system was shipped calibrated, this low-force verification is still worthwhile after transportation or a fixture change.
Calibration, maintenance and troubleshooting
Calibration should be treated as a system-level task involving the load cell, cabling, indicator and mechanical fixture. Start with no load and a stable mechanical zero, then apply a traceable known force appropriate to the system and perform span calibration using the actual indicator procedure. MNM does not identify the exact service-menu model on this listing, so do not assume OP-901, LP7515 or another button sequence without checking the indicator label. Recheck at several loads when possible. If the scale reads high or low, first inspect binding, side load, loose connectors, damaged cable and unstable power before changing calibration. If zero drifts, unload the cell completely and check that the fixture is not preloading or twisting the sensor. If Peak Hold seems inconsistent, compare slow controlled loads before blaming calibration.

Frequently asked questions
Is this a 15,000 lb scale or a 15,000 lb load cell? It is a complete force-measurement package built around a 15,000 lb S-type load cell and digital indicator. Can it measure compression? MNM lists the product for tension/compression; the fixture must apply force axially without side loading. Does it have Peak Hold? Yes, MNM advertises Peak Hold. Is it battery powered? The listing includes a rechargeable battery and power supply. Does it output data? The indicator description lists RS-232. Is the exact calibration menu published? Not on this product page; identify the indicator before entering a service menu. Is 2 lb readability appropriate for every test? No. Choose capacity and displayed increment based on the smallest force change you need to resolve and the maximum expected load, including safe headroom.
