Signal words:
This manual uses SIGNAL WORDS to indicate the likelihood of personal injuries, as well as the probable
seriousness of those injuries, if the product is misused in the ways described. Other signal words call attention to uses
of the product likely cause property damage. The signal words used appear below along with the meaning of each
word:
Identifies a hazardous situation which, if not avoided, WILL result in DEATH or
SERIOUS INJURY. Use of this signal word is limited to the most extreme situations.
Identifies a hazardous situation which, if not avoided, COULD result in DEATH or
SERIOUS INJURY.
Indicates a hazardous situation which, if not avoided, COULD result in MINOR or
MODERATE injury.
Identifies practices likely to result in product/property damage, such as operation that might
damage the product.
Safe use recommendations:
VESTIL strives to identify foreseeable hazards associated with the use of its products. However, material handling is
inherently dangerous and no manual can address every conceivable risk. The end-user ultimately is responsible for
exercising sound judgment at all times.
Electrocution might result if the crane contacts electrified wires. Reduce the likelihood that an operator
or bystander might be electrocuted by applying the following:
DO NOT assemble or use the crane in an area where it might contact electrified wires.
DO NOT contact electrified wires with the crane.
Material handling is dangerous. Improper or careless operation might result in serious personal
injuries. To reduce the risk of injury:
Before using the crane, always inspect the usage area for conditions that might require special precautions.
 DO NOT use a structurally damaged/malfunctioning crane. ALWAYS inspect the crane before each use according to the
inspection instructions on p. 21-22. DO NOT use the crane unless it passes every part of the prescribed inspection, i.e. do
not use the crane if it is damaged.
 DO NOT attempt to lift a load that weighs more than the rated load of your crane model (see Table on p. 2-4; capacity
labels on product; “Markings and labels” on p. 23).
 DO NOT stand beneath or travel under the crane if a load is suspended, and DO NOT permit any person to stand
beneath, or walk/stand under, the load.
 Inform all persons in the area that you are going to use the crane; instruct them to stay clear of the crane and the
supported load during operation.
 DO NOT allow people to ride on the load or climb on the crane.
 ALWAYS load the crane according to “Proper loading” recommendations on p. 21. Failure to properly load the crane
might cause the load to swing as it rises. A swinging load might cause serious injury.
 DO NOT use the crane if any label (see p. 23) is unreadable, damaged, or missing. Contact Vestil for replacement
label(s) as needed.
 DO NOT use the crane to transport loads. ONLY use the crane to lift loads!

Assembly instructions:
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.
Failure to apply the assembly procedure described in Steps 1-8 below constitutes misuse of the product.
ONLY qualified personnel should assemble the crane.
DO NOT modify the crane in any way. Unauthorized modifications automatically void the limited warranty (see p.
25) 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 Vestil 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.
Modifying the crane in any way automatically voids the limited warranty.
This crane can be used outdoors. However, it should be sheltered from the weather when not in use.
Inspect the crane for damage before each use.
UU Step 1 UU :[2,000 lb. (AHA-2-#-#) and 4,000 lb. (AHA-4-#-#) models only] Attach the leg weldments and yokes
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. Wind a knob into the yoke until the end of the
knob presses firmly against the leg.

Step 2:[NOTE: If you ordered a “Come-along” kit, perform Step 8 on p. 21 first.] Fasten uprights to leg assemblies
(AHA-6-#-# series; 6,000 lb. capacity models) or yokes (2,000 lb. and 4,000 lb. models).
Insert the uprights into the receivers of the leg assemblies or yokes. Align the 3
rd
pinhole in each upright with the
pinhole in the leg receivers as is depicted in Diagram 2 below.
Pin each adjustable upright to a leg assembly through the same (3
rd
) pinhole with adjustment pins (see Diagram 2A
below as well as the exploded parts diagrams on p. 5-16).

Step 3: Attach the uprights to the I-beam
1. Measure the flange width of the I-beam (see Diagram 3A).
2. Mark the centerline of the beam bracket and measure half
the width of the flange on either side of the centerline. (See
Diagram 3B).
3. Identify the 4 bolt holes in the bracket that lie just outside
the width of the beam flange.

Step 4: Fasten the I-beam to the uprights.
a. As shown in Diagram 4A, insert
1
/
2
in. structural bolts through the bolt holes of a beam clamp and through the
selected bolt holes in the beam bracket. Then, slide a lock washer onto each bolt and secure the bolts with
1
/
2
in. structural nuts. Do not fully tighten the nuts at this point.
b. As shown in Diagram 4C, insert the flange of the I-beam into the gap between the beam clamp and the beam
bracket; then install another beam clamp on the other side of the beam to secure the flange on both sides.
Diagram 4B shows
Step 5: Make sure that the I-beam is centered on both beam plates and that the beam clamps significantly
overlap the flange on both sides. Tighten the nuts to 50 - 52 ft·lb of torque.
Step 6: Stand the crane on its feet.
Rotate the crane onto its feet in a controlled manner. [For instance, attach a hoist chain to the I-beam and then
slowly raise the beam until the crane rotates to stand on its feet. Alternatively, raise the crane with a fork truck.
Position the forks under the beam and slowly raise it until the crane rotates onto its feet.]

ave moved to a
location away from and behind the fork
truck.
