PRODUCT DESCRIPTION
12 Ton Topless Tower Crane
This series of tower cranes, ranging from SATW1 has a horizontal jib frame, a jib-trolley radius-changing mechanism and a
hydraulic self-raising mechanism. It is original in design, reliable in operation and satisfactory in shape. Equipped with all
necessary safety devices, these cranes show a good speed-control capacity, satisfactory operating stability and high work
efficiency. They can be widely used for the construction of high-rise hotels, residential buildings, high-rise industrial buildings,
large-span factory buildings and tower-like buildings like tall chimneys.

Feature & advantage
1.suitable for all kinds of construction projects and can work under all kinds of work condition.
2.It has a high working speed, good speed-adjusting performance, steady operation, and high efficiency.
3.The crane has a complete set of safety devices, which can guarantee the safe and high-efficiency operation of the
equipment.
4. Three-speed motor and mono-speed ratio decelerators are applied in the lifting construction, which enables heavy load
low speed
and light load high speed.
5.Planet gear decelerator is applied in the circumgyrating structure, together with moment-limiting hydraulic coupler, which
can realize high load capacity, steady starting, and reliable operation.
