1. The tower crane adopts the upper slewing and upwards jacking apparatuses, rear-mounted jib pivot, and anchoring system.
2. The installation of pedestal has not too much requests about the auxiliary craning equipment and concrete base, which simplify the erection process.
3. The tower mast includes basic, standard and anchoring sections. The anchoring section can be interchangeable with the standard section due to the same geometric dimensions.
4. The hydraulic jacking system and the section leading device can increase or decrease the height of crane safely.
5. This series tower crane adopts advanced anchoring method and structure that the anchoring location can be flexibly adjusted to a wide application range.
6. The slewing mechanism consists of two world renowned planetary short-axis gearboxes, and three rows of cylinder slewing bearings. It can realize the variable slewing speed control, and stable, high precise slewing.
7. The hoist mechanism consists of the high quality planetary short shaft gearbox, Lebus drum and high strength compact type anti-twisting wire ropes.
8. The complete safety protection device can fulfill the multiple protection of the tower crane, referring to the force moment protection, overload limit, counterweight height limit, luffing height limit, mechanical limit, overtravel switch protection, angle induction protection, overflow, shutcut, over or under voltage, phase losing and phase sequence protections. What is worth saying is the absolute value coding luffing height limiter without metallic contact.
9. The electrical control and monitoring system has quite a number of smart functions, including the load recognition, zero-potential protection, rough handling resistance, wind speed monitoring, working and static state interlocking, tower mast monitoring,
10.The electrical control panels are enclosed in a box type electrical control center with an automatic temperature controller inside. The box can keep the electric elements at the best working status, and simplify the transportation of the control room. The electrical communication control system can simplify the physical cable linkage between itself and the actuators, so that the failure rate can be lowered.
