2 Post Lifts

Q: What makes your lifts better than the competitors?
A: We have explained for the last several years that our full line of Atlas lifts are manufactured to the same exacting standards as most of the "better known" domestic lift companies. All lifts are NOT built the same! There are similarities in the appearance of most above ground lifts, but the ATLAS LIFTS are built to standards that far exceed those standards incorporated by most other Asian lift manufacturers.

We also stock most of the lifts we advertise and have in-house service techs that can help with installation questions.

We have a parts department that stock all the parts needed for the current Atlas lifts we sell, and we also have parts for lifts that we sold over 10 years ago.


Q: Is the Atlas lift a "better" lift than the Master Series lift?
A: You sometimes hear companies distinguishing their products with the terms "GOOD", "BETTER", and "BEST." If we had to summarize the quality of our Atlas vs. Master Series, we would label Master Series "GOOD" and Atlas the "BEST".

The Master Series offers ONLY a limited one-year warranty on the major components of their lifts. The majority of Atlas Lifts carry a five-year structural warranty and one year hydraulic system/power unit warranty.


Q: Do you have both the Master Series and Atlas Lifts displayed in your showrooms?
A: We display the ATLAS lifts in our showroom and stock hundreds of Atlas lifts in our six National warehouses. Please visit any of our six locations to see your lift “in person”!


Q: How Does A 2-Post Above Ground Lift Work?
A: Click here to find out.


Q: What is the voltage on the motors of your lifts?
What is the horse power on the motors for your lifts?
A: All of our 2 post lifts are powered by a 220V motor.


Q: What kind of electrical wire should I use for my above ground lift?
A:

Size (gauge) of wire is dependent on the motor horsepower of the power unit and the distance of the power unit from the power source. Consult a professional electrical contractor if you feel it necessary, but the rule of thumb electrical requirements are listed below:

2-post lift with a 220V single phase motor: 10-2 wire (with ground wire)...30 AMP service



Q:

Does it matter whether the wiring is run from the ground or from above?

A: No, but if your goal is to make the electrical wiring connection to the power unit look "professional", then run the wire from the ceiling. When you try to "micro-manage" the exact position of the power unit column...and stub the wiring (in the concrete) next to the power unit column...the odds of getting it perfect are 50-50...at best. When you stub the wiring in the ceiling...you can position your lift properly and "drop the wire" directly to the power unit. You can enclose the wire in an attractive "wire cover" for a professional look.


Q:

Does the power unit motor cord have a male plug?

A: 220V motors on the power units are only available with either blank "pigtails" or “no pigtail”. (the customer must furnish the pigtail) . Customers must always provide the male and female ends.


Q:

Can I mount the power unit on any column?

A: Yes, but most lifts have only one column that can be used to mount the power unit.  This column has the mounting bracket (and maybe the lock release bracket) welded to it.  Make sure that you install that specific column where you want the power unit.


Q:

Can the power unit be moved to a remote location?

A:

Yes, but the extra hydraulic hose will act like a reservoir which may require more hydraulic oil to be added to the system. Ask your salesperson about “remote mounting” your power unit.



Q: Does my lift come with anchor bolts and/or the hardware to mount it to the floor?
A: Most of our two post lifts and most of our commercial grade four post lifts come with the appropriate number of anchor bolts to mount the lift to the floor. The customer will be always be responsible for providing the necessary hydraulic oil for the lift.


Q: What size concrete anchor bolts are needed?
A: Most 2-post lifts comes with enough ¾" x 5 ½" concrete anchor bolts for the initial installation of your lift. If you need to shim one column over one inch, then you need to purchase longer anchor bolts (3/4” x 6 ½”) 

Additional anchor bolts are available for purchase through Greg Smith Equipment Sales or from your local hardware or home improvement stores.


Q: Can I get a footprint dimension so that I can pre-drill the holes for my lift?
A: It is not necessary to pre-mount anchor bolts for our two post lifts. When you receive the lift, the holes in the base of the lift will be the guide through which you will drill holes and set anchor bolts. We do not recommend pre-mounting anchor bolts into the concrete.


Q: What are the concrete floor requirements of my lift?
A: 2-post lifts (under 12,000 LB. capacity):
Four (4) inches of concrete at 3000 PSI
12,000 pound two-post lifts (and higher capacity):
Six (6) inches of concrete at 3000 PSI is required.


Q: Do I need more (thicker) concrete in the area of the posts?
A: NO! Our listed concrete requirements are sufficient. But, if it makes you feel better, you may pour the concrete as thick as your pocketbook will allow.


Q: How long should I let my new concrete floor cure?
A: You may install (anchor) your lift (four days) after the concrete has been poured. You must wait a total of seven days before using the lift to its rated capacity.


Q: How do I determine the concrete thickness of my garage floor?
A: Drill a test hole and measure the thickness. Most garages will have at least four (4) inches. If you mount the lift and the "anchors" begin to lift out of the concrete over a period of time, you will need to relocate your lift or pour "new concrete pads" under the columns. There is also many types of epoxy concrete adhesives that help anchor your lift in marginal concrete.


Q: If I need to cut out my existing concrete and pour a new pad....how thick?
A: The new pad should be at least 4' by 4' and 10" thick. These new concrete pads should have "rebar" installed into the new pour and into the sides of the existing concrete slab.


Q: How large "stand alone" concrete pad is needed for an outdoor lift?
A: 2-post lift:
The concrete should be twice the required thickness of a "normal" concrete floor for the lift's weight capacity. (10K lift should have 8 inches of concrete) The "slab" should extend at least 24 inches past the outside of each column (side to side).


Q: I have a slope in my garage floor. Do I need to be concerned?
A: To allow for water drainage, many garages have a 1" to 2" slope from the back of the garage to the front. This minimal slope will not affect the safety or lift capacity of your lift.
Two post lifts (with one column mounted slightly higher than the opposite column) can  have the arms adjusted (equalization cables)...so that the arms (vehicle) are LEVEL when raised.

Columns can be "shimmed" with plastic or metal shims. If the column is to be "mounted with anchors"...make sure you use extra length anchors to compensate for the "shimmed" area above the concrete.


Q: Can concrete anchors be used if my garage has in-floor heating?
A: Yes, but you need to determine the "hot water pipe configuration" in your floor. If you are pouring a new concrete floor with hot water heat, then allow plenty of room for the columns to be installed. If you have in-floor heating already installed and do not have an accurate installation diagram; spray a small amount of water on your floor and turn the heating system to the highest setting. You may be able to see the outline of the heat pipes as the floor water begins to evaporate. Drill where it is wet. Dry areas indicate a heat pipe underneath.


Q: What type of hydraulic oil do I need to operate the lift?
A: Hydraulic fluid is the only recommended fluid/oil for your lift. AW 32 or AW 46 is the proper type of oil recommended by the lift manufacturer. Synthetic oil, automatic transmission fluid, and other substitutes are not recommended.


Q: How much hydraulic oil will I need?
A: Most two post require an average of 3-3.5 gallons of hydraulic fluid.

Hydraulic fluids can typically be found at most local parts, home improvement, or tractor supply stores.

Shipping regulations will not permit Greg Smith Equipment Sales from shipping hydraulic fluid. Hydraulic oil is available at our INDY location.


Q: How often do I need to change the hydraulic fluid?
A: Hydraulic fluid only needs to be added if there is a leak in the sealed system of the lift. Over time, extreme temperature fluctuations may create water particles to form inside the system over time. "MILKY" fluid should be evacuated and changed to ensure smooth operation.


Q: Can I mount and use my lift outside?
A: Yes, with certain limitations. Lifts must be mounted on a concrete surface of sufficient depth and integrity. Cold weather will affect the operation of any electric/hydraulic lift because the hydraulic oil will move slower in colder weather. Exposed metal cables need to be protected with a light weight marine-grade grease or WD-40. Cover the power unit to protect against moisture entering the motor.


Q: Can I mount my lift in an unheated garage?
A: Yes, but the hydraulic oil (in cold weather) will move slower because of its increased viscosity.

Trick: Place a "trouble light" with a 25 watt incandescent bulb near the plastic reservoir prior to use. (Be careful the bulb in protected and does NOT contact the plastic reservoir...reservoir will MELT) The heat generated from the light bulb will "warm" the hydraulic oil and increase the performance of your lift.


Q: Can I get a lift with a key lock out for the power unit?
A: Yes, but they are sold as an option and we believe that the key lock is just a gimmick that has proved to be unreliable. We sold them a few years ago...and the solenoids gave us headaches after 6 months!


Q: Can the overhead beam of a (2-post) lift be used to pull an engine?
A: No...use a cherry picker. The overhead cross beam (although made of heavy steel) is designed to be only a conduit for the hoses and cables!


Q: Do the carriage wear blocks need lubrication?
A: Yes...but very minimal! Please refer to your owner's manual.


Q: Where can I get parts for older lifts that are no longer produced?
A: Products are constantly changing, but Greg Smith Equipment should be able to locate most of the popular lift parts for lifts manufactured in the last ten years.

Most USA lift manufacturers are out of business...but even though the lifts were "made in the USA"...many of the parts have been coming from China for over 15 years. Many parts are generic...and although the quality of some of the parts may vary from the original manufacturer, the end result should be satisfactory.


Q: My lift "jumps" as it is raised or lowered. How do I prevent the "jumping"?
A:

The hydraulic system may have "air" in the system and the system needs to be purged.

If your lift has a "direct drive" cylinder, raise the carriage about one foot. Do not set the lift on its locks. Locate the allen screw on the top of each column. Open (just a little) ONE allen screw until you feel a small amount of air AND fluid flowing; tighten the screw. Lower the lift and then repeat the procedure for the other cylinder. Repeat if necessary.

For other lifts (with different cylinder configurations); raise and lower the lift a few times (with no weight) and hold the dump valve for a few seconds when in lowered position. You can feel the air flowing through the vent hole in the reservoir cap. The hydraulic system is being "bled".


Q: My lift makes a squeaky noise when it goes up and down. Can I eliminate it?
A: A noise coming from the lift while it is traveling up or down may be caused by a variety of reasons. A certain amount of sound is normal. However, certain sounds are indications that some adjustments may be necessary.

The columns need to be perfectly aligned (and level side to side) to ensure that the carriages are not contacting the inside of the column at some irregular angle that may create a vibrating sound.  This can be caused by improper installation.

The seals inside our cylinders are made to "fit" as tight as possible. On some lifts, there is a "break in period" that is needed to "soften" the seals inside the cylinder. The "stiffer" seals may vibrate or rub against the inside of the cylinder wall until the seal becomes more pliable after using the lift several times. We recommend the addition of four ounces of Caterpillar Hydraulic Oil additive #1U-9891 into the power unit hydraulic oil reservoir to help "speed up" the break in period. This Caterpillar hydraulic oil additive will soften the seals just enough to eliminate the noise, but will allow the seals to maintain their integrity to operate effectively.

There may be other factors that would produce some slight noise when operating the lift.
The lift experts at Greg Smith Equipment can provide you with many solutions to eliminate much of the noise. Of course, we cannot come to your location to perform these simple procedures, but we figure that if you were competent enough to install the lift, then performing some small noise reduction tasks should be very easy.


Q: How tight should the equalization cables be on my lift?
A: Raise the lift and DO NOT set it on the locks. Try to pull the cables together with the fingers of one hand. The cables should move toward each other about 1/3 of the way. If the cables do NOT move...they are too tight. If the cables can touch each other...they are too loose.


Q: Can I "adjust" an overhead lift to be a "little shorter"?
A: Certain models of our "overhead lifts" can be shortened "in the field", to accommodate some customers who are vertically challenged. Please call the lift technicians at Greg Smith Equipment to find out if the model of lift you are considering may be modified. If you are NOT mechanically inclined (or willing to pay someone that is mechanically inclined) then an "in field" modification will not be possible.


Q: I didn't get a manual or any instructions with my lift?
A: Yes...you probably did (and lost it).  However, most installation manuals are available on our web site. We can also mail, fax, or email a copy to you.


Q: What is the warranty on your lifts?
A:
  • Most Atlas and Direct Lift 2 post and 4 post lifts are warranted for (5) years on structural components and (1) years on hydraulic power units and cylinders from invoice date.

  • Master Series lifts have a (1) year parts only warranty.


    • Q: Does Greg Smith Equipment offer installation of its lifts?
    A: Greg Smith Equipment Sales works with dozens of lift installers throughout the USA and will be glad to provide names of these professional lift installers upon request. However, most lifts are installed by the customer with the help of some friends. Your local "handyman" can easily install these lifts with the help of our on-line easy to understand lift assembly guides.
