Operation
TO PREVENT SERIOUS INJURY and DEATH: The use of gantry cranes is subject
to certain hazards that cannot be met by mechanical means, but only by the
exercise of intelligence, care, common sense, and experience in anticipating
the motions that will occur as a result of operating the controls.
Wear ANSI-approved safety goggles, hard hat, heavy-duty work gloves,
and steel-toed work boots during operation.
Do not use without Locking Pins (7) in place and secured with R-Pins (18).
Do not exceed 1 Ton (2000 lb.) capacity.
NOTE: Once Assembly is complete, tighten ALL Bolts before initial operation.
The Gantry Crane can be used with a Push Trolley (ITEM 97392) and a hoist offered by Harbor Freight
Tools. Install trolley and hoist (both sold separately) according to manual instructions before operation.
Adjusting I-Beam Height
CAUTION! Use two people to
adjust the I-Beam height.
1. Remove the R-Pins (18) from the
Height Pins (7) and slide out Height Pins.
2. Once the Height Pins have been removed,
turn the Handles on both Pulley Assemblies
clockwise to raise the I-Beam.
Turn both counterclockwise to lower I-Beam.
CAUTION! To reduce the risk of tipping,
use crane at lowest height
possible for the application.

(shown in Figure H on the right side diagram).
4. Do not operate the hoist unless the
hoist unit is centered over the load.
5. Do not pick up a load in excess of the rated
load appearing on the hoist or load block,
except during properly authorized tests.
Do not use a hoist overload limiting device
to measure the maximum load to be lifted.

a designated person only.
However, always obey a stop signal,
no matter who gives it.

interference with other cranes and operations in the area.
2. Land any load that is attached to the gantry crane.
3. Use warning signs and barriers on the floor beneath the gantry crane
where overhead maintenance work creates a hazard.
4. Wear ANSI-approved safety goggles, hard hat, heavy-duty work gloves,
and steel-toed work boots during operation.
Frequent Inspection

2. Some components may require adjustment.
The following are examples:
a. Immobilize gantry crane before
lubrication by blocking casters.
a. operating mechanisms
b. limit switches
c. control systems
d. brakes
b. Lubricate all moving parts regularly using
grease. Lubricate kingpin bearing raceway
on each caster, as shown in Figure B.
6. After maintenance work is completed and
before restoring the crane to normal operation:

b. reactivate safety devices;
c. remove replaced parts and loose material;
d. remove maintenance equipment.
Testing
1. Test repaired cranes and cranes
that have not been used for a year
or more, before being used.
3. After testing in the unloaded state,
attach up to a 2,000 Ib. total load
(including trolley and hoist weight,
do not exceed trolley or hoist capacity)
and carefully retest to check proper
load control and to check brake operation
along the full length of the bridge.
2. First, with the crane unloaded,
check all functions of the crane, including:
