Danfoss Airflex Dragline Clutches & Brakes
A dragline can contain several independently identified clutch and brake assemblies. A useful inquiry specifies both the machine and the mechanism being serviced so procurement can distinguish the required unit from other components on the same machine.

Airflex options relevant to mining draglines
FHB floating-housing brakes
Danfoss identifies the FHB air-cooled brake for dragline applications.
DBA disc brakes
DBA brakes are spring-applied and pressure-released. Danfoss lists draglines among their applications.
Use these family descriptions to organize your inquiry. The exact assembly, dimensions, operating conditions and equipment requirements determine compatibility. Supply status is confirmed for the specific requested part.
What to document before requesting parts
Identify the mechanism
Specify whether the installed assembly serves hoist, drag, swing or another function. This describes the location of your inquiry; it does not establish which family is fitted.
Document the installed unit
Provide the brake or clutch nameplate, assembly drawing and existing part number. Photograph mounting details if the nameplate is missing or incomplete.
Define the parts request
Separate a complete brake inquiry from a friction-component or service-kit inquiry. List the quantities required for each identified assembly, especially when several similar units are installed.
Prepare your mining draglines parts inquiry
- Dragline manufacturer and model
- Mechanism and installed brake or clutch model
- Assembly / component numbers and photos
- Quantity per mechanism and delivery destination
Provide any original drawing, nameplate photo or previous purchase reference with your email. Keep original markings intact when photographing the assembly, and include units with any dimensions you supply.
For older Eaton Airflex equipment, retain the original identification in your inquiry rather than guessing a current substitute. A visible family name helps start identification, but does not replace the full part or assembly number.
Request a quick quote
Send your part references, quantities and destination to Alpha Trading International. Pricing, availability, lead time and any proposed replacement reference are confirmed with your quote.
Email your parts inquiry →Your email application opens so you can add documents and review the inquiry before sending.
Mining draglines: frequently asked questions
Are all dragline brakes FHB units?
No. FHB is a documented dragline brake family, but the installed assembly must be identified. Do not assume that it replaces another brake family.
Can you review a hoist or swing brake inquiry?
Yes. Name the machine mechanism and provide the fitted unit’s identification. The mechanism name alone does not determine the correct part.
What if the nameplate is unreadable?
Send clear photographs, available drawings, old purchase references and any legible markings. Additional identification may be needed before a quote can be confirmed.
Can I order several brake kits together?
Yes. List each assembly separately with its component number and quantity so the inquiry does not combine unlike units.
