Overview
The Single-Blade Lifting Tool is an auxiliary lifting and docking system for wind turbine blades, suitable for onshore and offshore use and for blade lengths from standard to ultra-long. It provides safe, stable and flexible handling to improve site productivity and reduce installation time.

Horizontal Type with Lifting Sling — Key Features

• High versatility: expands applicability by changing sling type and mounting holes.
• Lightweight design with optimized components for transport and handling.
• Rapid deployment: foldable beam arm enables integrated transport and minimizes on-site assembly.
• Dual-redundant wireless control with hold-to-run and two-button modes for safe operation.
• Limit switches and pressure monitors provide automatic stop to prevent blade damage.
• Series and modular design shorten delivery and simplify complex orders.

Horizontal Type with Lifting Sling — Components & Functions
Steel Structure
High-strength steel plate frame as the main load-bearing element; modular spans allow adaptation to various blade profiles for precise docking and stable attitude control.

Hoist Assembly
Coordinated multi-hoist control enables smooth lifting and fine orientation adjustment for accurate alignment at connection points.

Power System
Integrated independent power unit supports autonomous operation without external supply; provides stable power to electronic and hydraulic systems.

Release System
Supports automatic release and forced manual unlocking in case of power loss; position feedback and limit protection prevent jamming; interlock design avoids simultaneous sling slippage at both ends.

Clamping Mechanism
Hydraulic drive with automatic pressure-sensing stop; multi-axis spherical joint follows blade curvature; wear-resistant rubber pads protect the surface while ensuring secure grip.

Electrical Control System
PLC-based control with wireless remote; load, pressure and position sensors provide real-time monitoring and precise automated control during lifting.

Sling and Shackle
High-strength flat slings protect the blade surface; forged alloy shackles ensure reliable load-bearing performance.


Horizontal Type with C Clamp — Key Features

• Adaptable to multiple blade models by changing clamps.
• Designed for harsh offshore conditions with high corrosion class and elevated IP ratings.
• Operates in wind speeds up to 22 m/s, extending working windows.
• Dual-redundant wireless control with hold-to-run and two-button modes.
• Limit switches and pressure monitors provide automatic stop to prevent blade damage.
• Series and modular design for reduced lead times.
• Integrated installation/removal design permits use of the same equipment for mounting and decommissioning a single blade.
• Smart tagline system with automatic tension control to maintain stable and safe lifting.

Horizontal Type with C Clamp — Components & Functions
Steel Structure
Fabricated from high-strength alloy steel plates with precision welding for stable load-bearing capacity and adjustable spans.

Clamping Mechanism
Flexible gripping with rigid locking: wear-resistant anti-slip pads conform to the blade; hydraulic pressure is adjustable to suppress wobble or torsion during lift.

Tagline System
Real-time attitude adjustment with automatic tension control; self-locking brake counters wind-induced oscillation and twist.

Turning / Pitching System
Precise rotation of blade angle for rapid alignment with the hub, improving installation efficiency and reducing cycle time.

Power System
Integrated independent power unit with emergency start, overload protection and low-oil alarms for autonomous and safe operation.

Electrical Control System
PLC control with wireless remote; sensors enable automated control of angle adjustment, clamping and release.

Hydraulic System
Integrated hydraulic system using high-reliability components, with excellent sealing, minimal leakage risk, accurate control of clamping pressure and pitching speed, and overload/overpressure protection.
