Integrated Planetary Drive · Low Headroom · Compact Structure · Precise Lifting
The DQH European Electric Wire Rope Hoist is engineered for modern European-style single-girder crane systems, combining a compact low-headroom configuration with an advanced planetary transmission integrated inside the rope drum.
The hoisting motor transmits power to the planetary reducer through a flexible coupling. By integrating the reduction mechanism inside the drum, the DQH makes efficient use of internal space and reduces the external footprint of the hoisting drivetrain, contributing to a compact overall structure and increased available lifting height.
Combined with modular construction and optional variable-frequency control, the DQH delivers smooth lifting, precise load positioning and reliable performance for modern industrial material-handling applications.
The DQH features a hardened-gear planetary reducer integrated directly inside the rope drum.
Multiple planet gears share the transmitted load, providing high torque density within a compact mechanical structure. The integrated arrangement reduces the space required for an externally mounted gearbox and contributes to the compact dimensions of the complete hoisting mechanism.
Designed specifically for European-style crane systems, the DQH uses an optimized trolley and hoisting arrangement to minimize the vertical space occupied by the hoist.
The compact configuration helps increase available hook travel and makes more effective use of workshop height, particularly where building clearance is limited.
The hoisting motor is connected to the integrated planetary gearbox through a flexible coupling, providing reliable torque transmission while helping absorb shock loads and compensate for minor alignment deviations.
The resulting drivetrain is compact, smooth and well suited to frequent industrial lifting operations.
Dual-speed and variable-frequency configurations are available according to operating requirements.
VFD control provides smooth acceleration and deceleration, accurate low-speed positioning and reduced load swing, helping improve both handling efficiency and operational control.
The motor, coupling, drum assembly, planetary transmission, rope guide, hook block, travelling mechanism and electrical control system are arranged as functional modules.
This modular architecture simplifies installation, inspection, adjustment and component replacement while helping reduce maintenance downtime.
The trolley arrangement is specifically designed for European box-girder crane systems, providing a compact installation profile and stable cross travel.
Combined with variable-frequency travel control, the system provides smooth acceleration, deceleration and positioning across the crane span.
The DQH can be equipped with braking protection, upper and lower lifting limits, overload protection, motor protection, travel limits and electrical safety functions according to project requirements.
At the core of the DQH is its integrated planetary transmission.
Unlike conventional hoisting arrangements that position the reduction gearbox externally, the DQH installs the planetary reducer inside the rope drum, utilizing the internal drum space as part of the transmission architecture.
Hoisting Motor → Flexible Coupling → Integrated Planetary Gearbox → Rope Drum → Wire Rope → Hook Block
This arrangement shortens and simplifies the external drivetrain while maintaining the torque required for industrial lifting.
The planetary architecture distributes the transmitted load across multiple planet gears, providing a combination of compact dimensions, high torque density, smooth transmission and reliable operation.
Why Low Headroom Matters
In modern industrial buildings, available vertical space directly affects crane lifting performance.
The compact DQH configuration reduces the space occupied between the crane girder and hook, allowing the hook to travel closer to the crane structure. This helps maximize the effective lifting height without requiring additional building height.
For new factories and modern production facilities, this can provide greater flexibility in crane layout and material-handling system design.
