Irwin Rail-Based Cars & Locomotives Teams With Willison Couplers to Make a Great Pair

When it comes to mine and haulage, Willison Couplers are the best way to keep your rail cars on-track and maintain a safe workplace.

Willison Couplers can interlock without manual assistance. Their strength, simplicity of design and minimal operating parts make them the best couplers for loads ranging from capacities of 1 to 40 tons. Because of this wide range of load-bearing ability, Willison Couplers can fit any size car or locomotive.

Whether heavy-duty (20- to 40-ton capacity), regular-sized (5- to  19-ton capacity) or reduced-sized (1- to 4-ton capacity), Willison-equipped cars can be outfitted with shanks to accommodate any type of car construction, cushioning arrangement or track requirement.

Additionally, Willisons couple with every other Willison of the same size head!

Coupling Made Easy

With Willison Couplers, the pressure of one coupler against the opposite coupler forces the two couplers into alignment.

The two locks, now opposite each other, are pushed rearward into the coupler body until interlocking lugs come into contact with the coupler face. The angle of the lugs and face to each other guides the lugs of each coupler into corresponding interlocking jaws. When lugs have fully entered interlocking jaws, the locks are freed and returned to their normal position by the rugged stainless steel spring.

Thus, with the couplers in locked position, the lugs are held firmly in the opposite coupler’s interlocking jaw.

The Willison Coupler, along with train movement, performs the coupling operation without manual assistance or pre-setting of any mechanism.

Uncoupling Two Cars

Willison Couplers have many types of uncoupling mechanisms due to the many operating conditions in which rail cars must function.

To uncouple cars, the uncoupling mechanism raises the lock lever that retracts the lock, permitting couplers to part easily.  Only one coupler needs to be unlocked for the cars to separate.
