Q: What is the minimum concrete Requirement?
A
: 4" thick.

[top]

Q: What is the electrical Requirement?
A
: Most lifts are single phase, 230 volt, 60 Hz, 14.8 maximum amp draw and a 20 amp curcuit is needed, 3 phase is also available.

[top]

Q: What are truck Adapters and do I need them?
A
: If you work on trucks, or vehicles with running boards you need them. Truck Adapters are height extensions that allow the arm lifting pad to contact the frame or pinchweld when extra height is needed.

[top]

Q: Will a lift fit in my shop?
A:
Many twin post lifts today are designed to be installed in a shop with 12' ceilings. Many other styles, ingrounds, scissor racks can be installed in a shop with lower ceilings. The most prudent action is to get all the dimensions and measurements of your shop first or have one of our experienced sales staff visit your shop.

[top]

Q: What is a symmetric lift?
A
: Symmetric refers to the even distribution of mass. A symmetric twin post lift when properly operated, lifts the vehicle from its center area (measuring length). Vehicles center of gravity is placed directly between columns.

[top]

Q: What is an asymmetric lift?
A:
With an asymmetric lift the operator lines up the towers on each side of the car approximately with the front door-jams. Thus lifting the vehicle with more vehicle length behind the towers. Thus, easier access from vehicle. More weight is from the front of car so its a truer center of weight. Plus, these types of lifts can be narrower in design. Posts are placed forward of the center of gravity.

[top]

Q: Is my inground lift considered to be environmentally hazardous?
A:
The new federal EPA regulations:
The EPA has issued the new underground storage tank regulations and have excluded inground lift tanks from regulation. EPA's official position is as follows:
"In adopting the Federal Regulations (40 CFR 280) governing Underground Storage Tanks (USTs), EPA excluded several classes of tanks from regulation including equipment and machinery that contains regulated substances for operational purposes, such as hydraulic lift tanks [Section 280.10, (b), (3)] as well as UST systems that have a capacity of less than 110 gallons [Section 280.10, (b), (4)]. In the analysis of their rulemaking, EPA specifically cited hydraulic lift tanks for exclusion from the regulation. The Agency agreed with the reasoning that these types of tank systems pose a relatively low level of risk compared to other types of storage tanks because they contain small amounts of regulated substances solely for operational purpose; and a loss of regulated substance is accompanied by the faulty operation of the equipment, such that a loss of fluid causes knowledge of the loss."
For copies of the official EPA regulation (40 CFR, Parts 280 and 281), contact your local EPA office. Always check with local authorities to ensure you are complying with any local regulations.

Q: What is the difference between the "old-style" conventional inground lifts and the new environmentally safe ingrounds?
A:
JMC has many models of both styles. The conventional lift which we have all seen use approximately 60-85 gallons of oil. The new environmentally safe lifts are fully enclosed (sometimes called cassette lifts or canister lifts). The lift components are fully enclosed and the lifts like our Nussbaum top-lifts only need 6-8 quarts of oil. If a leak would occur - however unlikely - it would be contained in the canister.

Balancers

How large of tire/wheel will a balancer operate on?
What is tire matching or opti-ride?
Can I hide wheel weights on the back side of the wheel on my fancy aluminum wheels?
Can I balance wheels from large trucks like F350-550s or GMC 1 1/2 ton?
Do you have a solution for untrue centerholes on wheels?
Can I compensate for vibration broblems that are not wheel or tire related?
What is static vs. dynamic wheel balancing?

[top of faq]


Q: How large of tire/wheel will a balancer operate on?
A:
Basic specs.:
Rim width range 1.0-30''
Rim diameter range 3.4-35''
Max tire diameter 42'' other models 44''
Max wheel weight: 150 lbs
However Hofmann manufactures a balancer that does not require a hood
so it can do even larger tire and wheel assemblies. Hofmann also has models that will accommodate up to 60'' maximum tire tread diameter.

[top]

Q: What is tire matching or opti-ride?
A:
Hofmann has a patented procedure that atomatically matches the heavy spot on the wheel to the light spot on the tire. Thus allowing you to give a superior balance using the least amount of weight.

[top]

Q: Can I hide wheel weights on the back side of the wheel on my fancy aluminum wheels?
A:
Yes. Hofmann has 5 separate aluminum modes for hiding wheel weights on mag wheels.

[top]

Q: Can I balance wheels from large trucks like F350-550s or GMC 1 1/2 ton?
A:
Yes, with the proper optional adapters its quite easy.

[top]

Q: Do you have a solution for untrue centerholes on wheels?
A:
Yes, to ensure the best balance and smooth vibration free drive, the wheel must first be centered and torqued onto the balancer, just the same way it is mounted on the vehicle. It's that simple. Please visit our line sheet and click on Haweka Adapters for the complete picture.

[top]

Q: Can I compensate for vibration broblems that are not wheel or tire related?
A:
Yes, out-of-balance rotors, drums, drive shafts, etc. can be handled by using an "on-the-car balancer" or "finish balancer". This type of balancing is a suplement and should be considered a fine-tune after the traditional balance.

[top]

Q: What is static vs. dynamic wheel balancing?
A:
Static balancing uses a single plane (radial), that only addresses the "up and down" or hop imbalance as the tire/wheel rolls down the road. Static balancing attempts to only compensate for the heavy-spot mass in a plane that runs from the center of the hub area outward to the center of the tread area. This single-plane approach is not adequate to address today's sensitive vehicles or today's wider tires/wheels.
Dynamic balancing considers two weight planes. This balances both up-down and side-to-side imbalance. Dynamic, or "two-plane" balancing should always be used on today's vehicles.

Tire Changers

What is the term "Rim Clamp"?
Can I change Run-Flats?
How large of tire can I change?
Can I change ATV, Boat Trailer, Go-Carts or motorcycle wheels?

[top of faq]


Q: What is the term "Rim Clamp"?
A:
A "rim clamp" is just that. A tire changer that clamps on the back of the rim instead of the older conventional models that spun a cone down on the face of the rim. A rim-clamp tire changer clamps the wheel from behind and then with a tire iron against the demount head the operator milks the tire off the rim without ever touching the rim. Thus rim clamp tire cangers are mag/aluminum wheel friendly.

[top]

Q: Can I change Run-Flats?
A
: Yes, Run flats and other stiff side-wall tires can be changed much more adequately with the optional "Easy mount". The easy mount is a tire bead mount/demount device specifically made to mount on the side of a rim-clamp tire changer.

[top]

Q: How large of tire can I change?
A
: Depending on the model.
Maximum rim width 14''
Rim Clamps diameter 10''-23''
Maximum tire diameter 50''
Hofmann has models with capacity up to 96'' max tire diameter.

[top]

Q: Can I change ATV, Boat Trailer, Go-Carts or motorcycle wheels?
A
: Yes with optional adapters.

[top of faq]


Q: Who is Beissbarth?
A:
Beissbarth is a German manufacturer that has been in business since 1899. They are the largest manufacturer of computer wheel alignment in the world, with sales and service in over 72 countries. Beissbarth is recognized as the leader in alignment equipment technology by all of Germany's automobile manufacturers, including Mercedes-Benz, BMW, Porsche, Audi and Volkswagen.

[top]

Q: How fast can I have accurate live alignment readings?
A:
Using the Beissbarth "Random Choice" operating mode, your technician can easily have accurate, vehicle specific alignment readings in about 12 minutes. The Beissbarth system is also moveable, allowing you to use more than one bay if needed for performing wheel alignments.

[top]

Q: Can our technicians perform sensor calibration?
A:
Yes. Your technician simply access's the Beissbarth calibration program, and the software walks them step by step through the calibration procedure. The calibration is done electronically, there are no screws to turn. All Beissbarth Computer Wheel Alignment Systems come with the calibration fixture as standard equipment. The Beissbarth System also notifies you of the need to calibrate your equipment.

[top]

Q: Do we need to perform run out compensation?
A:
Beissbarth's exclusive "No Mar" tire clamping wheel clamps are designed so run out compensation is only required when being used on steel wheels. Since 70 percent of today's vehicles come with factory alloy wheels, which require no run out compensation, your technicians can save valuable time skipping this procedure while still maintaining maximum alignment accuracy.

[top]

Q: What wheel sizes can we clamp to?
A:
Beissbarth exclusive "No Mar" tire clamping wheel clamps can be used on any steel or alloy wheel from 10'' to 20''. Since the Beissbarth clamps, clamp to the vehicles tires, the wheel clamps can't fall off. There is no metal to metal contact with expensive alloy wheels using the Beissbarth wheel clamp. The only part of the clamp which contacts the wheel are 3 nylon extensions. Nylon adapters for "no lip" alloy wheels and truck extensions are included as standard equipment.

[top]

Q: Is it easy to operate?
A:
The Beissbarth operator software is extremely easy to follow. There are 2 different operating modes; one for the novice and one for the more experienced alignment technician.

[top]

Q: Where do we get service?
A:
Service is performed promptly by JMC Automotive Service Equipment. We have a complete stock of Beissbarth replacement parts and have Beissbarth trained technicians. Beissbarth USA is located in Nashville, Tennessee if additional parts and technical support are needed.

[top]

Q: Are yearly updates expensive?
A:
Yearly vehicle specification updates are $ 195.00 per year. Updates are usually available in late June. Updates come loaded on 3 1/2'' floppy discs with easy to follow instructions for downloading onto your Beissbarth Computer Alignment System. The Beissbarth Computer Wheel Alignment System comes with 35 years of vehicle data for import and American vehicles as well as vehicle specific digital photos and diagrams or alignment procedures. After market alignment shims and parts information is at your finger tips from Specialty Products.

[top]

Q: What about hidden after the sale options?
A:
What you see is what you get. The only option with your Beissbarth ML 4000 "Cordless" Computer Alignment System is the undercar remote display. Everything else is standard down to the cabinet dust cover.

[top]

Q: What about low vehicle spoilers?
A:
No problem. With the Beissbarth ML4000 "Cordless" Computer Alignment System with 8 CCD toe sensor technology, if a low spoiler is sensed during the alignment, the patented Beissbarth "spoiler program" is activated. The spoiler program then reroutes the front toe beam around the rear of the vehicle, allowing easy and accurate alignment on even the most difficult to align vehicles.
