3. The outline of the crane is international fashion model and very perfect, enjoyed by the home and abroad users.
4. The crane has many working mode, it is used in different condition. Such as: outrigger stationary, undercarriage stationary, anchored to the building and mobile, so that it is applied in different construction projects.
5. It has high working speed and good regulated speed performance. The technique of the stepless speed regulated and frequency altering is used in the hoisting mechanism, the trolleying mechanism and the slewing mechanism, so the crane works more smoothly and reliably.
6. The main electric components are used world-renowned products, which service life is 3~4 times longer than China-made counterparts with less failure, simple maintenance and reliable.
7. All equipped safety devices are mechanical or mechanical-electrical integrated products, and adapt to all badly conditions to ensure the crane working reliably.
8. Large-radius hoisting jib suspended by double rigid pull rods, featuring good jib rigidity,light jib weight, small jib cross-section, small wind resistance and nice-looking appearance andseveral jib lengths, it is satisfied different construction needs.
9. Out- hung operator cabin, featuring excellent field of view, spacious interior, could install air conditioner; it is satisfactory working environment to the operator.
10. The tower cranes have certificates of ISO, CE, etc, suitable for safety and environmental protection.
11. Optional tower crane black box offering, to show the correct and specific working condition of tower crane every day.
