Step 8: If you have a “Come-Along” kit used to manually adjust the height of the crane, install the cable loops before
inserting the teletubes.
Use Instructions
NOTE: Before using the crane for the first time, perform the “Initial Inspection” described on p. 22.
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
teletubes, 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 diagrammed in Fig.
6.
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. Move the crane and load
separately to the desired work location.
Only use the crane to lift loads.
Twist the cable loop into an “8” and fold the top of
the 8 over onto the bottom part of the 8 (this will
double loop the cable). Then slide the doubled
loop onto the yoke.
