Unlike T-type tower crane, the luffing crane is designed to lift its jib. The T-type tower crane, such as topless cranes,
operate by moving a trolley along the fixed jib, while the luffing crane adjust the distance by lifting or lowering the
entire jib without trolley moving along the jib. In places where spaces are limited, such as in urban areas, tower cranes often interfere with nearby buildings. In this case, you will need the luffing carne, which hold the short counter-weight
jib and can adjust the angle of the front jib.
