Self-raised Tower Crane

Leading technology of working mechanism
(1)Hoisting mechanism: Matching with frequency transforming & multipolar dynamo resistivity for timing. Stably shifting impules the electric fence gently. Multipolar dynamo works stably, it is simple and economic with gentle impulisvie currency when starting and shifting.
(2)Trolleying mechanism: Frequency transformer and wire wrapping motor can be applied to conduct speed regulating. It is economic and convenient to operate.
(3)Slewing mechanism: Frequency transformer and wire wrapping motor can be applied to conduct speed regulating.
