Trade Shows have been cancelled for 2020 and we are disappointed as you are. But in anticipation of this reality, we have been working hard to create a new-to-the-world virtual booth for our devoted Customers. You will hear more about this in the next weeks, but look for:
DYNOmite views this year as an opportunity to engage with you in ways we haven't been able to in the past. Please visit our show page to register for additional information as it becomes available.
Bring your used dynamometer back to life. We offer third-party absorber, roller, and electronic-controller replacements, including replacement parts manufacturing. Land & Sea can convert many other manufacturer’s older or discontinued (single axle) chassis dynamometers over to true AWD, with full electronic axle synchronization, at a fraction of the cost of a new installation.
Our CNC Machining & Fabrication provides you with a dynamometer manufacturer’s factory quality – even for your custom one-off projects. Our in-house facilities include: computerized 2-D and 3-D CAD/CAM/FEA design, three or four-axis computerized conventional and surface milling, full CNC turning, “traction-groove” machining, and dynamic spin balancing of large rolls (up to 65" diameter x 12' long and 4,000+ pounds each), high-definition plasma-stream cutting, HD forming, TIG and MIG welding, powder-coat finishing and large-oven curing, surface-mount electronic repair, etc. Send your prints for a quotation.
Large roll repairs don't have to be a large problem. However, most machine shops are unable to handle turning and dynamic balancing the high-inertia and huge-diameter rollers used in typical chassis dynamometers. Fewer still have any experience at it. No wonder rebuilders turn to us. We manufacture a full range of dynamometer rolls on a daily basis… it’s what we do. Not only can we refinish the running surface of your worn rolls, they will probably work better than they did when they were new – read further to find out why.
The machining of new or worn roll surfaces drastically improves power transfer (while reducing tire-damaging heat buildup). These special deep-machined grooves are much more effective than short-lived friction coatings or cheap cosmetic (diamond shaped) cut or press knurling. Peak torque limits will often be more than doubled via this reconditioning. Besides refinishing the running-surface area of your rolls, we can also replace most worn (or bent) axle shafts – to a true running condition. Reconditioning will often save thousands of dollars (versus a replacement part) even on just a single roll or axle repair. Call for technical advice and quotations on our “Traction-Groove” machining service.
The balancing of large-diameter rolls, flywheels, impellers, and shafts reduces the damaging vibration loads. Rebalancing of rolls and rotors (after remachining) is critical for safe, vibration-free performance – we always recommend it. Installing out-of-balance components will guarantee premature bearing failure.
Add Electronics & Controls to your old analog emissions dynamometer or speedometer calibrator and you can perform road-load simulations, for AFR testing, on it. Even many simplistic inertia-only type dynos can be upgraded into fully programmable, and again useful, engineering tools by the addition of one of our DYNOmite Data Acquisition Dynamometer Conversion packages. After the installation, you will be able to perform controlled acceleration sweeps and long steady-state tests. Systems typically include: an appropriate capacity eddy-current absorption unit, electronic load control with power supply, full- bridge (temperature-compensated) torque transducer (normally an S-beam load cell), 28-channel DYNOmite-Pro DAQ computer, magnetic absorber-RPM pickup, temperature thermistor and a 28- channel data harness. That, plus a switch over to our DYNO-MAX™ software, is all it takes to bring your extinct “dynosaur” right into the 21st century!
