13-2-9 Precautions for special types of crane operation
(0099-0037-0E)
(1) Tandem lifting
1) Work with two cranes of the same model.
2) Select cranes which have ample capacity for the job.
3) Appoint one signaler for the entire operation.
4) As a rule, control the cranes by single lever operations and
avoid compound lever operations.
5) Avoid slewing operations.
(2) Crane operation on sites with underground areas
1) Choose the number of parts of line with ample capacity for
the job.
2) Choose outrigger setting positions with particular care.
3) Be particularly thorough in all aspects of signaling.
4) Since the load is out of your view, proceed with extra caution
in all crane operations.
5) If the number of parts of line on a wire rope is unsuitable for
the boom length, the hook will not reach the ground level and
the wire rope will wind backwards onto the drum and suffer
damage.
