Linear actuators for compact ­performance and reliability

4th Quarter 2015 Shaft power components

The new CMLA electromechanical linear actuators from Columbus McKinnon can handle the toughest operating conditions. They can be mounted in any position, making them suitable for applications in the food, chemical, process and metalworking industries. Available in four load specifications from 500 to 1300 kg with rated outputs of 5000 to 13 000 N, they offer excellent reliability in an even more compact and powerful unit.

As the unit is pre-wired, installation is ‘plug and play’ simple. The optional ball screw and low gear ratio make for high lifting speeds. The CMLA is suited for precision applications due to its precise positioning and its repeat accuracy. It also offers constant lifting power through the complete stroke, its standard stroke length being up to 1000 mm. The motors, brakes and drive mechanism are designed in accordance with DIN EN 60034-5, protection class IP65 for outdoor use in a temperature range from 0 to 60C.

While a three-phase AC 3Ph 400 V (50 Hz) motor is standard, a direct current 24 V motor is an option on the P50 and P70 models. Efficiency is enhanced thanks to a two-stage straight-toothed spur gear and an optional ball screw. All rotating parts run on high quality ball bearings. Mechanical limit switches are standard, while variable magnetic limit switches are an option. The CMLA is fitted with a self-locking trapezoidal screw, with a ball screw as an option. An anti-turn device is standard and no external control elements are needed. The unit is also supplied with a wide range of accessories.
