, PT6516

For restricted work spaces, the flat top tower crane is an ideal choice. It's easy to install and dismantle the jibs in mid-air, and because these cranes are generally smaller, several can be used on the same construction site. For high-rises surrounded by smaller buildings, the top slewing tower crane has a better chance of completing the job. With no pulling rod, these topless tower crane's jibs are wider and more stable with less chance of buckling.
