Do you need precise, robust and durable actuators for adjustingyour systems? Then we are the right partner.

Since developing the actuators, ZIMM has already proved this inseveral small and large solar power plants. In doing so, 1- and2-axis-trackers have been equipped comparably. The system isdelivered with software according to the required customerspecification for single or composite systems.

Besides photovoltaic, our trackers ZSA are also suitable for satellitesystems, wind energy, facade technology, shadowing technology,door actuation and also for industry.

ZIMM Solar, like the Screw Jack Systems, follows the long lasting,established philosophy of the modular construction kit.The ZIMM Actuators ZSA are assembled individually from stockstandard components providing short delivery times as standard.

We would be pleased to develop a concept for linear drivessuitable for your particular application, this means we willexamine your requirements and then offer you a tailor-madesolution, based on our standard program - supplemented withyour wishes.

We look forward to hearing from you.

The fact that insurance companies and solar park operators knowthat a quality product is in use, which avoids damage and down-time and therefore can possibly avoid higher costs, will have

a positive influence on the profitability analysis.

Our standard program with 3 sizes covers the majority ofdifferent applications.

In addition, ZIMM also offers further options and products inthe sector of ZIMM Screw Jack Systems, produced for loads from2.5 kN to 1000 kN.

Visit our homepage www.zimmsolar.at or contact our ZIMM SolarTeam in person. We will be pleased to advise you!

ZIMM has been involved in linear, electromechanical drive systemsfor machine and plant construction for more than 30 years andcan support you with the right products and expert advice.

ZIMM is an international operating company from Vorarlberg -located in Western Austria - and is a family business that hasdeveloped into a global player and delivering its products allover the world.

ZIMM has developed the ZSA series of solar actuators especiallyfor outdoor applications and the requirements of solar plants.The actuators are designed and manufactured to be operated tolast at least 20 years with a low maintenance requirement.The actuators stand out with their robust and stable constructionand the usage of quality components.

Nevertheless, we can offer you an excellent price-performanceratio by serial production and simple installation - a lasting andexcellent product.

Pivot brackets LB for Actuator ZSA

Pivot brackets LB are made of corrosion-resistant steel and aredesigned for the full nominal load.

ATTENTION:When planning your own design, please consider that not onlythe axial loads (Fx) but also the resulting bending forces (Mx)on the bolts must be absorbed by your design.

NOTE:

Customer-specific pivot brackets can also be deliveredon request.

*ZSA-21-LB have only 2 mounting holes
