O EM quality
rebuilding brings your used dynamometer back to life. We offer
third-party absorber, roller, and electronic controller repairs, including
replacement parts manufacturing. Land & Sea can convert many other
manufacturers 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.
CNC machining and fabrication
provides you with a dynamometer manufacturers 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, TIG and MIG welding, surface-mount
electronic repair, etc. Send your own prints or photos for a quotation.
roll repairs need not create large problems for you. 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
on a daily basis
its 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.
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 weld and then grind refinish
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.
spin balancing of large-diameter rolls, crankshafts, propellers,
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.
electronics and 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
. 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!
