3_1_1_e_060706 01.08.2006 17:52 Uhr Seite 2 RACO ELECTRIC CYLINDER® MODULAR SYSTEM – HEAVY DUTY SERIES (TYPE 1) SIZE 9,10,11 up to 6m HIGH-PERFORMANCE ELECTRIC CYLINDERS: EXTREMLY ROBUST, POWERFUL AND PRECISE The high power modular system to fit your individual needs! Electric cylinders of sizes 9 to 11 have been developed according to a joint design principle which fulfils the requirements for linear drives for extremely high actuating forces or high loads. For this reason, development work on the "Heavy Duty" range has focused on providing sturdiness and durability even under the toughest of conditions. Extreme operating conditions such as heat, cold, dust, humidity and vibrations define the benchmark for the reliability of RACO's electric cylinders, which are used in bridges, locks, satellite / solar systems, lifting and crane equipment both onshore and offshore. Features & Benefits: High force, long stroke and high speed available High reliability even under extreme operating conditions High positioning accuracy and reproduction of former values Modular System to fit your individual needs Solid construction principle with high safety coefficient All sizes with multiple-speed trapezoidal thread spindle or ball screw Covered thrust unit with internal torque support Actuator controlled by force limiter or limit switch Performance data, dimensions and weights for actuator size 9 (max. 160 kN) up to size 11 (max. 1000 kN), Stroke up to 6000 mm RACO Schwelm

RACO ELECTRIC CYLINDER® MODULAR SYSTEM - HEAVY DUTY SERIES (TYPE 1) PERFORMANCE AND TECHNICAL DATA trapezoidal thread spindles (type M1R...) or ball screws (type K1R...) with profile geometry optimised used as a central drive element. The electric cylinders of the types equipped with a ball screw. On account of their higher specific efficiency, ball screws are pre- ferred in applications where a long service life with high realized. The rolling contact bet- ween the balls and paths in the spindle nut system results in only very slight friction in comparison with trapezoidal thread spindles. The...

Where heavy loads must be lifted, the avoidance of uncontrolled lowering of the load is particularly important in terms of safety, RACO Schwelm especially with a vertical installation...
