PERBANDINGAN PRODUKTIVITAS LUFFING CRANE DENGAN HAMMER HEAD CRANE PADA PROYEK HIGH RISE BUILDING STUDI KASUS: MENARA ASTRA PROJECT, JAKARTA
ABSTRACT: The economic growth
has contributed to the increasing number of high rise building construction
mostly in big city especially Jakarta. In practice, the construction of high
rise building project is aided by heavy equipment that is hammer head crane
which is known as one of tower crane type. However, with the increasing number
of high rise building construction, the hammer head crane space that usually be
used in high rise building project is limited, hence, another type of tower
crane called luffing crane that can be working optimally in the limited space
is needed as the alternative for hammer head crane. For the consideration in
choosing the type of which tower crane that should be used in the project, it
requires the productivity analysis that is related to the equipment efficiency
for each column, slab and beam works. From the research that has been
conducted, it shows that the hammer head crane productivity is 13% higher fo
column work and 65% higher for slab and beam works than luffing crane’s. With a
note that in horizontal movement, luffing crane is excel more than hammer head
crane. So overall, it can be concluded that in a condition where hammer head
crane still can be operated in a limited space, its productivity is still
higher than luffing crane productivity that operated in the same condition and
surrounded. While luffing crane is used if hammer head crane is utterly can not
be operated.
