Versatility of H6H Hydraulic Winch Leads to New Applications

No doubt about it, the Allied hydraulic winches demonstrate an amazing level of versatility and adaptability. Take a look at these interesting new

winch applications:

Caterpillar 963D Track-Type Loader

A modern track loader is not an easy machine for add-ing a rear-mounted towing winch. Instead of a vertical rear face as usually seen on a crawler dozer, it has a rear-mounted engine, radiator and counterweight where a winch would be installed. Little details like that did not stop Fabick Cat of Missouri USA from supply-ing their customer with a new 963D track loader with rear-mounted Allied H6H winch. Working closely with Allied for technical support, the Fabick team developed a mounting bracket to secure the winch to the rear frame. They used the standard ripper hydraulic circuit to power the winch, needing only to develop the con-necting hoses to complete the hydraulic system. (See also the Allied winch on John Deere 755C track loader in Winchlines, Vol. 26 No. 2.)

One challenge for this type of installation is that the operator is unable to see the winch when sitting at the controls. Fabick sourced a closed-circuit video camera to mount above the winch and a display screen to mount inside the cab.

The 963D with winch will fi nd a wide variety of uses in oilfi eld applications. The winch gives the operator greater confi dence in tackling more diffi cult ground conditions, knowing that self-rescue and equipment rescue are at the tips of the fi ngers.

Liebherr PR724 Crawler Dozer

Liebherr, a diversifi ed manufacturer of heavy equip-ment, cranes and hydraulic equipment based in Europe, has been supplying hydrostatic crawler dozers since 1972. Their dozers have been widely used in Europe for many years, and are starting to make a stronger entry into the North American market. No surprise that a winch requirement would arise before too long. Liebherr dealer RECO Equipment in Ohio USA needed

The Caterpillar 963D track loader with the Allied H6H winch. A video camera at the top of the radiator grille allows the operator to see the winch in operation.

The Liebherr PR724 now has the option for Allied H6H winch. The “Plug and Play” H6H winch can be installed easily on the pin-mount rear face of the dozer.

a winch on a PR724 dozer. The Allied H6H winch was the perfect size, well-known in the North American market, and readily adaptable. Working closely with Liebherr Engineering in Telfs, Austria, Allied developed a specifi c mounting bracket and hydraulic arrangement for this dozer model. For the fi rst installation, Allied engineering staff was on-site to verify the fi t-up and operation of the winch.

This is just the beginning of a more complete winch offering on Liebherr dozers. Look for additional news later this year.

Caterpillar D6T Track-Type Tractor

The Cat D6T is normally outfi tted with the Allied W6G PTO-driven winch. An electrical utility service contrac-tor had been using the Allied H6G winch on D6N, and was now looking to upgrade to D6T. They needed the precise line control that a hydraulic winch can offer. The new H6H was readily adaptable to both D6N and D6T. Both D6N and D6T can now take either the W6G PTO winch or the H6H hydraulic winch.

Komatsu D61-23 Crawler Dozer

Komatsu has just released their newest crawler dozer, the D61-23, replacing the D61-15. It is a hydrostatic dozer, similar to D51-22. The Allied H6H winch, cur-rently used on D65-16/17, will be offered for this new dozer as well.

Tigercat 635D Grapple Skidder

Allied has been the OEM supplier of skidder winches to Tigercat in Canada for many years. The WH410 winch, a hydraulic derivative of the very successful Al-lied PTO-driven W400 skidder winch (previously from Clark and Lufkin), is installed on most Tigercat skidders. A recent demand for a more powerful skidding winch on Tigercat’s largest skidder, the 635D grapple skidder with rear bogie axle, resulted in a collaborative effort between the Allied and Tigercat engineering teams to adapt the H6H hydraulic towing winch to this log skidder. The H6H gives the 635D both high line pull for rescue work in diffi cult terrain and fast line speed for production skidding in areas where the terrain is unsuitable for traditional grapple skidding.

The common theme in all these applications is the Allied H6H winch. With its state-of-the-art variable displacement motor and modular drive train, the winch can be quickly adapted to a wide variety of hydraulic supply systems and control schemes. This fl exibility shortens the engineering lead time substantially, allow-ing Allied to maintain its edge as a responsive supplier to the heavy equipment community.

The H6H hydraulic winch is available for the fol-lowing crawler dozers and track loaders:

Caterpillar D6N, D6T, 963D

Komatsu D61-23, D65-16/17

John Deere 750J/K, 850J/K

Liebherr PR724

The massive Tigercat 635D in a tropical logging environment needed a winch to match. The H6H is perfect for this heavy-duty application.

The H6H winch is based on the very successful W6F and W6G PTO-driven winches. The hydraulic motor is housed inside the winch frame, out of harm’s way. Using different hydraulic motor settings and planetary gear ratios, the H6H winch is readily adaptable to a wide variety of hydraulic inputs.

Winch Manuals at your Fingertips

Did you know that you can view and download any of the

Allied winch manuals free of charge? Maybe your cus-tomer wants a replacement Operator’s Manual for the used machine he is buying. Perhaps the repair shop is looking for old Hyster winch spare parts. Sometimes a customer just needs a few selected pages from the service manual to get them going again. Web access is the perfect way to address these and similar require-ments.

You’ll fi nd lots more on our web site. Take a look at the suggested spare parts lists. There’s even an animated display of the inner workings of an Allied winch. Check it out! Go to http://www.alliedsystems.com/winch/winch.htm

Dealer Training Knows No Limits

When it comes to travel in support of its dealer organization, Allied takes a back seat to no-body. Just recently, Territory Manager James

Smith and Winch Engineer Eric Predeek were in Jakarta, Indonesia to deliver three days of intensive winch ser-vice training to a team of about 20 technicians from Cat dealer P.T. Trakindo. Trakindo is one of the largest Cat dealers in the world. Their customers know and trust the Allied winch as the reliable choice in the rough conditions of the Asian tropics.

A key focus of the training was the W6F winch for Cat 527 track skidder. The Cat assembly plant for the 527 TSK is immediately adjacent to the Trakindo Training and PDI facility in Jakarta. In the more remote areas where skidding loads are the heaviest, Trakindo selects the Allied winch for its reliability and acceptance over other winch choices.

Most of the winch users are in remote locations. The service technicians often do not have the luxury of a well-provisioned shop for doing diagnosis and repair. A key part of the training was instructing the techni-cians on how to properly diagnose winch problems so that they can quickly decide what can be repaired in the fi eld and what needs to go back to a repair facility.

Trakindo service technicians from six far-fl ung branches traveled up to 2,000 miles (3,300km) to the Jakarta Training Center for detailed service training on the Allied winch.

Allied Supports Caterpillar in Bonneville Power Administration Fleet Upgrade

Take a look at this impressive upgrade to the fl eet of dozers owned by the Bonneville Power

Administration (BPA), based in Port-land, Oregon. It includes three Cat D5K crawlers equipped with Allied H4A hydraulic winch and six Cat D6K crawlers equipped with Allied H5C hydraulic winch. Caterpillar De-fense and Federal Products Group purchased the winches from Allied, and had them installed by local Cat dealer Peterson Cat in Portland.

BPA will use the dozers in maintain-ing their extensive network of pow-er transmission lines throughout the Pacifi c Northwest. The D5K dozers will be used in part to pull power poles out of the ground. The Allied integral arch on the winch provides greater lift and more control over the pole as it comes out of the ground. The D6K dozers will be used for power-line sagging applications. The hydraulic winch delivers precise control over the position of the line, allowing the power line to be tensioned to exactly the right level.

The Allied H4A and H5C winches feature a “plug-and-play” design concept. The dozers did not need any winch-ready options from the Cat factory, which shortened the lead time and reduced cost considerably. With a non-winch-ready dozer in stock, you can deliver a winch-equipped dozer at much shorter lead time and at lower cost, thanks to this approach.
