Rotorblade maintenance platform UVM10L

The Blade Maintenance Platform UVM10L is used as a rotor blade traversing system for the temporary insepction of rotor blades in wind energy systems fitted on circular steel or concrete towers. The UMV10L is an easy to install solution to reach most of the installed blades of about 2MW turbines.

UVM10L consists of three main functional groups and it is made entirely from welded aluminium:

• Two asymmetric working half-platforms connected to the base frame by an undercarriage. They can be moved apart or closer together separately or at the same time in order to adjust them precisely to different rotor blade cross-sections.
• One base support frame with side mounted trapezoids, on which the hoist parallelograms plus Tirak rope hoists (X1030 P) and Blocstop fall arrest devices (BSO 1030 EFA) are fitted
• An electric positioning frame with adjustable bumper rollers ensures a stabile ascent and descent along the turbine mast

UVM10L main safety features among many others are:

• Automatic triggering of the Blocstop fall arrest device in case of inclination of the platform and overspeed
• Emergency Power Supply: if power supply fails an emergency descent is always possible
• Sliding clutches : the gear motors for the two platform halves are fitted with sliding clutches to prevent damage if any of the components are blocked during intentional movement
• The parallelogram inclination can be adjusted using the Bravo lever hoists and this ensures that the platform’s centre of gravity can be re-aligned at anytime. Monitoring of the wind speed and visual alarm for the operators.
