2 Grupo Resa combines the global manufacture and support services to satisfy the customer's requirements and needs. It has developed a line of elevators aimed at solving the access problems of wind towers, tower cranes and other industrial installations. Each manufacturing stage, from the reception of materials used, the finish of different products is subjected to exhaustive monitoring, culminating the process at our test benches, where the quality controls demanded by the current legislation for our products are performed. Our reason of being is to provide customers with a service that always exceeds their expectations, with a professionalism that proves both the human and labour quality of our employees and an unimpeachable integrity. RELIABLE ELEVATOR Designed and manufactured by Grupo Resa, the elevator is the result of many years of experience operating in all kinds of difficult access installations. The safety characteristics and the efficient performance of Grupo Resa differentiate us from the rest. With integrated safety devices against excessive speed and the facility to reach and activate the manual descent, you can be absolutely sure of performing reliable and safe operations for many years. ADVANTAGES OF THE RACK AND PINION SYSTEM The R-300 elevator incorporates a rack and pinion elevation system for a safe and reliable operation. A pinion is directly ducked to each drive reducer, assembled on the cabin. Each pinion engages with the mast rack allowing the cabin to go up and down, and stop the movement using electrical integrated disk brakes in each motor. The elevation system through a rack and pinion system requires a minimal maintenance and is extremely safe, reliable and versatile. Easy and safe to assemble and disassemble, without the need of external machinery. The assembly of the sections and the bracing to the facade is carried out from the upper floor of the cabin.

5 APPLICATIONS The current demand for lifting systems is increasing in all types of industrial sectors, hence Grupo Resa has developed a line of elevators which is outstanding for its versatility, reliability and safety. One of the fields of greater implementation are wind turbines, to perform inspection and maintenance tasks of these towers, to periodically access the gondola and transport two operators and their tools inside the tower.

INTERNAL CONTROLS Our elevator has constant pressure controls which the operator uses both inside and outside the cabin to assemble the masts.

Moreover, the system guarantees the elevator cannot move at any time while the enclosing are open. - Door locking systems: it uses a safety locking switch system during door closing.

- Multi-speeds: the user can lift up to 48 m/min in service and at 12 m/min during assembly.

7 DATA ELECTRICAL SPECIFICATIONS Power - Frequency * 400V / 50Hz Rated power 2 x 1,1 KW Rated current 2x3A Supply cable 5 x 4 mm² Service Mode-Man Present Cabin interior 13 m / min *Standard elevator with power 400V 50Hz, with possibility, upon request, of manufacturing it for any supply network. INTERNAL CONTROLS Our elevator has constant pressure controls which the operator uses both inside and outside the cabin to assemble the masts. OPTIONAL COMPONENTS - Safety systems for door closing: they prevent the access of people to the service elevator area unless the elevator is in safe accessibility conditions. Moreover, the system guarantees the elevator cannot move at any time while the enclosing are open. - Door locking systems: it uses a safety locking switch system during door closing. - Floor calls - External controls: the elevator has controls for constant pressure or by pulse, which the operator uses on each floor for loading and unloading. - Multi-speeds: the user can lift up to 48 m/min in service and at 12 m/min during assembly. - Floor recognition: the elevator is controlled by an electronic system that manages the operation and the recognition of the floor without having to install skids and position switches Therefore all the position switches installed on the elevator, are emergency switches or passive safety switches. A graphic touch matrix screen is supplied which indicates the floor we wish to go to and the floor where it is at the time. The plants are programmed from this terminal, elevating the machine and memorising its position. - Overload floor system: includes elements that interrupt the operation in the case the user has exceeded the load capacity.
