Use instructions:
NOTE: Before using the crane for the first time, perform the "Initial Inspection" described on p. 21 below.
Crane operators are responsible for operating the crane in a safe manner. To reduce the likelihood of
serious personal injuries or death resulting as a consequence of negligent operation:
 Only use this crane if you are qualified and trained to use it. The operating instructions in this manual supplement
safe crane and hoist operation practices learned during your training program.
 ALWAYS apply the safe material handling practices learned from your training program.
 All personnel not participating in the use of the crane must stay out of the area during use. Be certain no part of any
person or object is under any part of the boom (I-beam) or the suspended load at any time and particularly before
lowering it. Instruct all persons to remain at a safe distance during operation.
 Always carefully watch the boom and any load hanging from it while using the crane.
 Always follow the hoist and trolley manufacturers' instructions regarding proper use of their products.
 BEFORE the load is connected to the hoist, lock or immobilize the casters (for instance with chocks).
 DO NOT use the crane and notify your supervisor and authorized maintenance personnel if: 1) you observe any
damage or hear unusual noise during operation; or 2) you observe any warping or deformation of the beam, the
adjustable uprights, the load hook or chain/cable.
Proper loading:
Position the trolley and hoist directly
above the load. Center the trolley and hoist
above the center of the load and position the
long axis of the I-beam above the center of
the load. Proper positioning is illustrated in
Diagrams 8A & 8B.
Connect the load to the hoist chain/cable,
according to the instructions supplied with
your hoist and the method applied at your
work site; then raise the load only as high as
is necessary to position it. Once the load is
properly centered above the work location,
lower the load until it is fully supported by
the ground or work surface and disconnect
the load from the hoist. Return the crane to
its storage locations.
If you must move the load to a different
location, return the load to the ground or
other supporting surface, e.g. pallet, and
disconnect it from the hoist.
crane and load separately to the work
location. Only use the crane to lift loads.
Inspections and maintenance:
Owner(s)/end-user(s) of the crane should apply Occupational Safety and Health Administration (OSHA) crane
inspection procedures (see 29 CFR 1910.179 by visiting http://www.osha.gov/ and navigate to "Regulations"; then to
"General Industry" standards, section 1910.179. However, the end-user should realize that occupational safety and
health laws and regulations of the state where the crane is used, rather than federal OSHA regulations, are controlling
authority). Inspections are classified according to the intervals at which inspection should be performed. The identity
of the components to be inspected and the degree to which those components wear, deteriorate, or malfunction
determine how frequently you must inspect the crane. 29 CFR 1910.179(j) describes the various inspections the end
user is responsible for performing on this crane:
1. Initial inspection — before a new or modified crane may be used for the first time, it must be inspected to
insure normal condition. Conduct a "Frequent inspection" as described next.
After the first use, the crane end-user/owner must conduct the following 2 types of inspection:
