2. ALL RIGGING COMPONENTS MUST HAVE A WORKING LOAD LIMIT THAT
IS EQUAL TO OR GREATER THAN THE COMBINED WEIGHT OF INTENDED
LOAD PLUS THE Kenlift®.
3. UNDER NO CIRCUMSTANCES SHOULD ANY COMPONENT USED AS RIGGING
TO THE Kenlift®BE OF A RATED CAPACITY LESS THAN THAT OF THE
Kenlift®.
4. DO NOT RIG UNPROTECTED NYLON SLINGS OR WIRE ROPE DIRECTLY
THROUGH LIFT BAIL.
5. IF USING EQUIPMENT OTHER THAN A CRANE: USE RIGGING OF
SUFFICIENT LENGTH TO PREVENT CONTACT BETWEEN Kenlift®AND
EQUIPMENT.

Section V. Operation.
Before attempting to use the Kenlift®device ALWAYS perform a test lift on the
intended object(s) to confirm proper operation. DO NOT use a Kenlift®to handle
objects beyond the rated capacity or range.
A. Automatic operation:
1. Ensure that the Kenlift®’s capacity and range are appropriate to the median barrier wall to be
handled.
2. Ensure pads are clean and free of debris or contamination.
3. Position the Kenlift®at or near center of object to be lifted.
4. Lower Kenlift®onto object, taking care to minimize impact.
5. Ensure that all persons are clear of the Kenlift®and wall.
6. Release tension on the rigging to cycle the actuator.
7. Raise the Kenlift®and load in a smooth motion. Do not “jerk”.
8. Deposit at desired location.
9. Release tension on the rigging to cycle the actuator. (Note: avoid undue slamming of the
Kenlift®into open position to prolong actuator life.)
10. Remove the Kenlift®(Kenlift®is latched in open position automatically)
B. AVOID JARRING, SWINGING, AND OTHERWISE UNNECESSARY
MANIPULATION OF THE LOAD.
C. AVOID HANDLING OF LOADS OFF CENTER.
DANGER
!
Manipulation of the Kenlift®by ground personnel for the
purpose of alignment with load shall only be done with
Kenlift®suspended above the barrier. KEEP ALL HANDS
AWAY FROM Kenlift®DURING OPERATION.
DANGER
!
Tip: The majority of wear on the Kenlift®, pads and associated components
results from shock loading, impacting, and poor alignment of the Kenlift®with
the load. Minimizing these incidents will greatly extend the life of the Kenlift®
and consumables.
Pads and surfaces of the load that come into contact with the
pad surfaces MUST BE CLEAN and free of any foreign
material or coating that could compromise the grip.
DANGER
!

D. DO NOT USE THE Kenlift®TO PICK MULTIPLES OF ITEMS IN A SINGLE PICK.
E. OBSERVE ALL SAFETY PRACTICES ASSOCIATED WITH OPERATION OF HOIST
MACHINERY.
F. DO NOT USE A Kenlift®TO DRAG LOADS.
G. DO NOT ALLOW LOAD (BARRIER) TO CONTACT ANY SURFACE/OBJECT WHILE
BEING HANDLED.
The Kenlift®barrier handling device produces grip
proportional to and dependent on the weight of the
barrier wall. It is for this reason that while in
operation the Kenlift®and wall NEVER be allowed to
contact other items.

Section VI. Maintenance
A. Daily:
1. Visually inspect the Kenlift®for signs of stress and wear.
2. Check that bolts and nuts are snug.
3. Ensure free movement of all components.
4. Ensure that all warning labels are present and readable.
5. Check that the actuator mounting screws are snug and seated.
6. Lubricate all moving mechanisms with penetrating oil.
7. LUBRICATE ACTUATOR WITH LIGHT PENETRATING OIL ONLY
(WD40™)
8. For Pads:
a. Check that all pad mounting bolts and nuts are tight.
b. Verify freedom of rotation for pad angle.
c. Ensure that pad material is sound, and not de-laminated from backing plates.
d. Ensure that pad mounting bolt heads are min.3/32” below the surface of the pad.
e. Ensure pads are clean and free of any foreign material or substance.
B. Annually*
1. Remove pivot bolts and coat with grease.
2. Inspect holes, pins, bolts etc. for wear. See sect VII for criteria.
3. Remove actuator, clean and lubricate with light penetrating oil –check for signs
of wear, replace if necessary.
* Frequency depends on usage, environmental conditions, etc.
