ASSEMBLING THE CRANE
If the crane is improperly assembled, it might malfunction and result in serious personal injuries.
Read this instruction manual in its entirety before assembling the crane; only assemble the crane if you fully
understand both the associated risks and the manufacturer-approved assembly procedure discussed below.
•
Follow the assembly procedure described in Steps 1-8. If you have any questions about the assembly process,
•
ONLY qualified personnel should assemble the crane.
•
DO NOT
modify the crane in any way. Modifying the crane automatically voids the
and might make the crane unsafe to use.
•
DO NOT
use the crane if you notice damage to, or deformation of, the beam, uprights, or any part of the leg
assemblies. Using the crane despite weakness of a structural component could result in crane collapse.
•
DO NOT
use the crane if any of the hardware (bolts, nuts, clamps, etc.) is damaged or missing. Contact the
to order replacement parts.
•
DO NOT
use the crane if any of the casters are damaged. A damaged caster may cause the crane to tip over, and
the possibility that the crane will tip increases while it is used to hoist or support a load.

:
(for 2,000 lb. (AHA-2-#-#) and 4,000 lb. (AHA-4-#-#) models only)
Insert the end of each leg into one of the leg openings in the yoke as shown below. Fasten the legs to the yoke with
clevis pins (33-112-034 or 28-112-031) and secure the clevis pins with hitch pins. Insert a knob into the yoke until the
end of the knob presses firmly against the leg.
Step 2: (for Come-Along accessory kit only) If you have a “Come-Along” kit used to adjust the height of the crane),
install the cable loops before inserting the uprights into the yokes. Twist the provided cable loops into a figure “8”; then
fold it over onto itself (this will double loop the cable). Slide the doubled loop around the receiver of the yoke.
