2-POST LIMITATIONS AND ADAPTER
USAGE:
REV (2/9/2006)
2-POST LIMITATIONS:
ALL MOHAWK 2-POST LIFTS ARE FOR INDOOR USE UNLESS
SPECIFICALLY QUALIFIED AND MODIFIED FOR A CUSTOM
ENVIRONMENT.
ALL MOHAWK 2-POST LIFTS MUST ACCOMPLISH THREE MAIN
CRITERIA IN ORDER TO LIFT A VEHICLE SAFELY:
1. PROPER FRAME ENGAGEMENT WITH PADS. ALL 2-
POST FRAME ENGAGING LIFTS ARE DESIGNED TO LIFT
STANDARD VEHICLES WITHIN THEIR RATED
CAPACITY BY THE VEHICLE FRAME. IF SUITABLE
FRAME CONTACT LIFT POINTS CAN NOT BE REACHED
OR ACCOMMODATED BY THE LIFTING PADS, THE
VEHICLE MUST NOT BE RAISED WITH THE LIFT. REFER
TO VEHICLE MANUFACTURER LIFTING POINT
SPECIFICATIONS (AND VEHICLE LIFT POINT LABEL PER
SAE J2184, VEHICLE LIFT POINTS FOR SERVICE
GARAGE LIFTING).
2. PROPER CENTER OF GRAVITY PLACEMENT OF
VEHICLE ON LIFT ENSURE THAT THE CENTER OF
GRAVITY OF THE VEHICLE LIES CENTERED BETWEEN
THE LIFTING ARMS. THIS SHOULD PLACE THE CENTER
OF GRAVITY OF THE VEHICLE IN LINE WITH THE
CENTER OF THE POSTS AS WELL.
3. PROPER LOADING OF ARMS. INDIVIDUAL ARM
CAPACITIES ARE ¼OF THE RATED LIFT CAPACITY,
AND MUST NOT BE EXCEEDED. FOR INSTANCE, A 10,000
LB RATED 2-POST LIFT HAS ARMS THAT ARE RATED
FOR 2,500 LBS EACH. IT IS POSSIBLE THAT A 10,000 LB
VEHICLE CAN OVERLOAD THE ARMS ON A 10,000 LB
LIFT IF THE FRONT AND REAR LOADING ARE NOT
EQUAL.
WITH RESPECT TO HEAVY ENDED VEHICLES SUCH AS FORK
TRUCKS, DELIVERY VANS, PICKUP TRUCKS, ETC, ATTENTION
MUST BE MADE TO ENSURE THAT THE PER ARM CAPACITY OF
THE LIFTING ARMS IS NOT EXCEEDED AND THAT THE CENTER
OF GRAVITY OF THE VEHICLE LIES CENTERED BETWEEN THE
LIFTING ARMS.
SPECIAL SAFETY PRECAUTIONS MUST BE OBSERVED IN
APPLICATIONS INVOLVING VERY LONG AND VERY SHORT
WHEELBASE VEHICLES. 2-POST LIFTS ARE NOT DESIGNED TO
RAISE STRETCHED LIMOS AND OTHER TYPES OF LONG WHEEL
BASE VEHICLES. AS A RULE OF THUMB, THE VEHICLE LENGTH
ON A 2-POST MUST BE LIMITED TO 4 TIMES THE LENGTH OF THE
ARM SPREAD TO RAISE IT. THE CENTER OF GRAVITY ON THIS
VEHICLE MUST LIE BETWEEN THE LIFTING PADS TO
ACCOMPLISH THIS. NOTE THAT SOME VEHICLES, PER VEHICLE
MANUFACTURER GUIDELINES, ARE NOT TO BE RAISED BY THE
FRAME. REFER TO VEHICLE MANUFACTURER GUIDELINES FOR
PROPER LIFTING TECHNIQUES.
THIS LIFT IS NOT INTENDED, NOR DESIGNED, TO LIFT VEHICLE
FRONT OR BACK ENDS USING ONLY TWO ARMS.
CARE MUST BE OBSERVED WHEN REMOVING ANY HEAVY
COMPONENTS FROM A VEHICLE AND THEREBY DRASTICALLY
SHIFTING THE VEHICLE CENTER OF GRAVITY (I.E. ENGINE
REMOVAL, TRANSMISSION REMOVAL, ETC.). THE USE OF JACK
STANDS AT THE FRONT AND REAR ENDS OF THE VEHICLE IS
HIGHLY RECOMMENDED WHEN PERFORMING THIS TYPE OF
WORK.
ADAPTER USAGE AND LIMITATIONS:
THE USE OF HEIGHT ADAPTERS IS COMMON FOR MOST LIFTING
SITUATIONS TO ACCOMMODATE HIGH FRAMES AND LOW
OVERHANGING BODIES OF VEHICLES.
