The versatility of this modular electric wire rope winch, coupled with maximum safety and reliability, makes it the ideal choice for demanding working environments where safety is the top priority.

Our ATEX-certified ETSW-EX cable winch complies with the strict standards of the ATEX Product Directive 2014/34/EU and the Machinery Directive 2006/42/EC and has been specially developed for use in explosive atmospheres.

Its main feature is its safe and spark-free operation, which is guaranteed by innovative safety features.

The cable winch has a variety of protective mechanisms that drastically reduce the risk of sparking and therefore potential ignition in environments with flammable mixtures of air, gases or dust.

This is achieved, for example, by special wire ropes with copper-plated load hooks that minimize electrostatic discharges. The electrical control unit in a pressure-resistant encapsulated housing also ensures safe operation.

Special surface coatings and antistatic materials ensure a further level of safety by minimizing the generation of sparks. Sophisticated ignition protection encapsulation and the use of antistatic materials such as plastics, paints or stainless steel make this cable winch a reliable choice in a wide range of industries.

Limit switch / end position switch-off:
The limit switch with protection class IP65, designed as a spindle limit switch, is installed on the drive side as an extension of the drum axis to save space. In the basic version, the limit switch is designed with 2 contacts as an emergency limit switch. In order to prevent the emergency limit switch from starting up during operation, the limit switch is optionally available with 4 contacts to enable it to start up during operation. All 4 contacts are adjustable to allow the greatest possible flexibility of use. If an optional overrunning clutch is required, the limit switch is mounted on the opposite side of the operator.

Frame:
The frame essentially consists of two side plates connected to each other by threaded rods, which provide the necessary stability and are used to hold the drum and to mount or suspend the cable winch on the respective surface. The side plates are designed to accommodate both the drive unit and various accessory options. The functions of your winch can therefore be expanded at a later date, e.g. by adding a freewheel clutch.

Drive:
The cable winches in the ETSW series are available in the standard version as electric cable winches with a three-phase brake motor with an operating voltage of 3 PH / 400V / 50 Hz and a spur gear. Thanks to its duty cycle of 60% and protection class IP55, the winch is suitable for almost uninterrupted use under the toughest conditions, even outdoors.

An ETSW winch with other operating voltages or drive types is available on request.

Winch drum:
The standard version of the ETSW cable winch is initially designed with a smooth drum body. On request or if there are technical requirements (e.g. reducing the distance to the first deflection), we can also supply the electric cable winch with a grooved cable drum. Due to the modular design, every ETSW winch can also be converted from a smooth to a grooved rope drum after completion. It is also possible to obtain optional stainless steel versions or cable winches with multiple cable outlets.
