USING THE CRANE
Before using the crane, perform a
inspection described on p. 12.
WARNING
Risk of serious personal injuries or death.
•
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 applied at your work site. Acquire a copy of the most
recent edition of ASME B30.17 and apply all operation, inspection, maintenance, and care
recommendations.
•
ALWAYS apply the material handling practices learned from your training program.
•
All personnel not participating in the use of the crane must stay out of the area while the crane and hoist
are used. 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.
•
Only use this crane on level concrete surface.
•
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 I-beam, the upright, base frame, fastened connection points, especially anchorages,
the load hook or hoist chain/cable.
•
DO NOT operate a hoist with a twisted, kinked, or damaged chain or rope. DO NOT operate a rope hoist
unless the rope is properly seated in its groove.
LOADING THE CRANE
Center the hoist above the center of
the load. The long axis of the I-beam
should align with the center of the load.
Proper positioning is illustrated in Diagrams
A & B.
Connect a load to the hoist according
to the instructions supplied with your hoist
as well as the lifting methods applied at
your work site; then raise the load only as
high as is necessary. 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.
RECORD OF SATISFACTORY CONDITION (THE “RECORD”)
Thoroughly inspect the crane after installing and assembling it and
before
putting it into service. Record the
condition and appearance of each of the frame members (I-beam, upright, base frame), tie rods, yokes, and all
fasteners (anchor bolts, bolts, nuts, pins, etc.). Thoroughly photograph the crane from multiple angles. Include
close range photographs of the anchoring hardware, all labeling, and all fastened connections (I-beam to
upright; upright to base frame; yokes to tie rods and yoke brackets). Add the photographs to the RECORD.
Collect all photographs and writings in a file. This file is a record of the crane in satisfactory condition. Compare
to this RECORD to determine whether the crane is in satisfactory condition.
