Eldro Brakes
Electromagnetic brake systems for safe crane operations
Eldro electro-hydraulic thruster brakes are the fail-safe braking workhorses of industrial cranes: spring force applies the brake, and an electro-hydraulic thruster releases it whenever the drive is powered. If power fails, the brake closes automatically and holds the load. KRANHAUSS has manufactured crane equipment in Ankara since 2004 and supplies Eldro-type thruster brakes made to order, in drum and disc configurations, to customers in more than 50 countries.
How Eldro Thruster Brakes Work
An Eldro brake pairs a spring-applied braking mechanism with an electro-hydraulic thruster. While the drive motor is energized, the thruster holds the linkage open and the brake stays released; the moment power is cut — by the controller or by a fault — the springs close the brake and hold the load. That fail-safe logic is why thruster brakes are standard on crane hoisting and travel drives and heavy equipment such as belt conveyors. Because the thruster damps the closing motion, engagement is smooth and progressive, which limits shock loads on couplings, gearboxes and the supporting structure.
Drum and Disc Configurations: Selection Criteria
KRANHAUSS supplies Eldro-type brakes in drum and disc configurations to suit the drive layout. The right unit depends on a handful of parameters you likely already have: required braking torque, drum or disc diameter, motor power, switching frequency, and the operating environment — indoor, outdoor, dusty or corrosive. The duty class of the crane mechanism matters as well, since frequent stops call for generous thermal reserves. If you are replacing an existing brake, the mounting dimensions and the thruster's stroke and force define the envelope; share a drawing or photos and we match it.
Made to Order in Ankara Since 2004
Every Eldro brake leaves our Ankara facility built to order, not picked from a shelf — which is also why we publish no list prices. KRANHAUSS operates under company-level certifications including ISO 9001, ISO 14001, OHSAS 18001, ISO 3834-2 and EN 1090, with CE marking, and supplies crane equipment for demanding sites such as steel plants, ports and cement factories. Whether you are specifying brakes for a new crane or sourcing a replacement for a unit in service, send us your drive data and we will engineer a matching proposal.
Frequently Asked Questions
What makes an Eldro thruster brake fail-safe?
The brake is applied by spring force and released by the electro-hydraulic thruster, so it can only stay open while the system is powered. Any loss of supply — an emergency stop, a tripped breaker, a cable fault — lets the springs close the brake immediately and hold the load without any operator action.
Can your brakes replace an existing thruster brake on my crane?
In most cases, yes. Because each unit is made to order, we can match the mounting dimensions, drum or disc size and thruster characteristics of the brake currently installed. Send the nameplate data, key dimensions or a drawing of the existing unit, and our engineers will confirm compatibility before quoting.
What information should I include in a quote request?
Share the application (hoist, travel or conveyor drive), the required braking torque or motor power, drum or disc diameter, supply voltage, operating environment and quantity. If anything is missing, our team follows up — we prefer to clarify details up front rather than quote a brake that does not fit your drive.
How do you handle delivery and shipping terms?
KRANHAUSS exports worldwide and has shipped to customers in more than 50 countries. Delivery times, packaging and Incoterms are agreed individually for each order, since made-to-order equipment varies in scope. Share your specification through the quote form and you will receive a proposal covering both the brakes and the commercial terms.
