Company Profile

We Supply and Repair Drivetrain and Hydraulic Cylinders

Who We Are

Hydraulic Engineering Repair Services (HERS) was established in 1971 under the name Hydraulic and Air Services (Pty) Ltd and changed its name to Hydraulic Engineering Repair Services in 1996.  HERS became a wholly owned division of Hudaco Trading (Pty) Ltd in December 2015.

HERS has a proud tradition of supplying a superior mix of quality and affordable products designed to meet specific customer requirements.  By listening to the needs of customers and adapting to changing environments, we are able to constantly update and improve our service.

With nearly five decades of hydraulics and drivetrain experience, we have created a foundation of excellence from which to support our industry and customers.

Drivetrain Division

Our Drivetrain division was established just under 20 years ago and we are an official distributor to the Southern African market of two leading suppliers of drivetrain equipment – Kessler and Dana. We have been an agent of Kessler for over a decade.

New products

We supply new axles, transmissions and torque converters to a wide range of markets for a variety of uses – agriculture, construction, cranes, material handling, mining, harbour equipment, marine applications, lift trucks, aircraft ground support, agriculture, telehandlers, heavy trucks and special vehicles.

Repairs

The Drivetrain Division is housed in a 1800 square metre factory with a dedicated stripping bay and ten work bays, most of which are serviced by overhead cranes.

A test bay with an axle test bench and another with two dynamometer test benches conduct tests on completed transmission repairs.

Over the past ten years the HERS drivetrain team has proven to be a leading repairer of other drivetrain components, such as Clark, ZF and CAT, to name a few.

With our modern drivetrain test bench, we are able to reduce operational costs for our customers by repairing and refurbishing equipment to OEM specifications.

Training

All HERS technicians have undergone official Kessler training on their full range of products.

Spares and Service Exchange Parts

We also carry a substantial quantity of spares and also offer a large range of service exchange stock to reduce production time losses through component failures on site.

Our Markets

We design, manufacture, refurbish and repair a range of hydraulic cylinders for customers in the mining, off-highway, construction, material handling, plant hire, steel, airport and harbour markets.

Design & Engineering

HERS uses the latest Autodesk Inventor CAD software to model hydraulic cylinders. This ensures that all components function and fit perfectly prior to any manufacture taking place.

Machining

All components are machined according to international ISO tolerance tables.  Workshop personnel have individual sets of measuring equipment that are calibrated regularly to meet the requirements of our ISO 9001:2015 accreditation and audited by Bureau Veritas Certification.

Testing

All cylinders are tested on a hydraulic test bench.

Drifters & Impact Hammers

To strengthen our hydraulic offering, we recently added a capability to service and repair drifters and impact hammers as well.
