If you're looking for a crane scale or dynamometer....you've come to the right place.


Johnson Scale Co. "The overhead weighing experts" We have over  100 years of experience in selling and servicing Dillon, MSI, Intercomp, Chatillon and CAS industrial crane scales, tension dynamometers, load monitoring instrumentation as well as RF wireless data acquistion. Our overhead weighing products are used throughout the world in virtually every industry; including aerospace, agriculture, petrochemical, utility, transportation, marine, aluminum, forestry, iron and steel, and nuclear.

Whats the difference?

  • A Dynamometer displays the tension force exerted between the two attached shackles. Originally inveneted in 1936 and still in use today. It is generally used to determine the tension in a line or suspended weight. Current models include simple, easy to use mechanical models, battery operated digital models, and wireless versions that let you combine up to 16 individual readings on one hand held controller.
  • A crane scale is a dynamometer outfitted with equipment appropriate for suspended weighing, such as large openings in the shackles, or non-swivel, swivel or bearing swivel hook on the bottom.
  • A Tension meter is simply a lever operated job specific dynamometer that quickly measures tension in overhead wires, guy wires, cable guardrails, etc.
  • Force control switches and load monitoring devices provide switch outputs which change state (open/close) at specific forces. Generally, they require no power to opeate and are connected to a variety of devices such as relays, lights, alarms or to the motor controller to stop crane movement. A force control switch may have mulitiple switches as needed for triggering at several loads The switch settings are usually set at the factory to the specific load(s) desired by the customer. Force control switches are available as in-line or clamp-on versions.

Typical use include:

  • Measuring tension in guy wires
  • Meauring tension in elevator cables
  • Fuel rod changes
  • Avaition and naval
  • Measure tension on line cords
  • Oil and gas industry.

Please Note: Many of our competitors still advertise the older Edjr dynamometers and AP EXtremes. Please be aware that any models starting with 36190 or are designated APxtreme are old stock and were discontinued a few years ago.

Each and every Dynamometer we sell includes a NIST traceable calbration certificate unless otherwise noted.  Additionally, our ISO 9001:2008 system will send you a reminder when your instrument is due for annual calibration.

When it comes to overhead weighing our customers safety is our number one concern. Please DO NOT use products that cut corners and are not overhead safety qualified. Please call us with any questions.

Our knowledgeable sales representatives are ready to answer your questions about product specifications, features, performance and benefits. Whether it is a new purchase, repair or NIST traceable calbration, Our goal is that prompt order delivery, quick turnaround, and easy access to techinical support is always within reach.
