EMG Electro hydraulic actuators
Electrohydraulic EMG actuators
Electrohydraulic EMG actuators convert electrical energy into mechanical energy and perform mechanical work during a specific section of the stroke. The proven versatility of the electrohydraulic thrusters EMG ELDRO® and ELHY® in different areas of operation has led to its widespread use in mining, steel, port and building industry applications.
Electrohydraulic actuators EMG ELDRO® and ELHY® can be utilised in combination with different operating elements, for example in the following areas of application:
-Lifting and lowering mechanisms
-Locking and unlocking by displacement of load-securing wedges or securing hooks
-Lowering of the wipers on conveyor belts
-Valve actuators on hydraulic presses
EMG ESZ Electro-Servo Cylinder
EMG ESZ Electro-Servo-Cylinder
The Electro-Servo-Cylinder developed by EMG is used as a control and positioning cylinder. It converts by means of a Planetary Gear Thread (PGT) the rotation generated by a threephase current motor into a linear movement. The function principle is based on a rolling motion at low friction and consequently low wear.
The standard model of the Electro-Servo-Cylinder consists of the following components:
- threephase asynchronous motor
- spindle with planetary gear thread, thrust housing and piston rod with knuckle
- rotating lock of piston rod
- housing with pivot
HKAL EMG hydraulic cylinder
HKAL Hydraulic Compact Actuator Linear
With the Hydraulic Compact Actuator Linear (short: HKAL), EMG has come up with a new actuator unit combining tradition and innovation. Its great adaptability as well as its rugged technical design and economic efficiency allow HKAL to be used in a broad range of industrial applications including:
- mining and conveyor technology
- mechanical engineering and plant construction
- power plant engineering
- valve engineering
- hydraulic steel constructions
- renewable energy (solar energy, water energy, etc.)
