For helicopters with life capacities of 1000 to 25,000 lbs (454 to 11,350 kg)

Since 1990, Isolair has worked with the most progressive helicopter logging contractors and forest management agencies in the Pacific Northwest and Canada. The result is our Logger 6000 series of hydraulic grapples. These units have been tested, refined and proven in all types of logging and clean-up. They offer the features our customers have asked for as well as the rugged, yet lightweight, construction necessary to survive under extreme loads.

The smaller units are made of aluminum and steel to give maximum payload. Also, their hydraulic systems are completely self-contained which eliminates the need for long hydraulic lines. The larger units are all steel designed to "stand up" to the incredible stresses imposed by large unbalanced bundles of logs. They are operated by a helicopter-mounted auxiliary hydraulic pump available from Isolair. Breakaway connections allow the unit to be instantly jettisoned in case of trouble.

The pilot has complete control of the grapple opening and closing on the cyclic and ,with experience, will develop remarkable dexterity in handling. The small 6000-1 has effectively cleaned streambeds and removed slash on aircraft such as the MD 500 and Bell 206. Isolair also has custom brush fork tines available. And, like all Isolair products, the Logger series is user oriented, carefully engineered, and made in the USA to aircraft standards by committed craftsmen.

When we produced our first prototype Logger Grapple in 1990, operators were still using chockers and ground crews. There were doubts that helicopter logging costs could be significantly lowered. The first user, contract l offing in Oregon's Mount Hood National Forest with a Bell 204, was delighted with the immediate benefits. He noted reduced crew and related insurance costs, full pilot control, flexibility in scheduling, and the ability to sort and deck logs at the landing area. He caught the attention of area forest managers, who became enthusiastic supporters of the Logger 6000.

In today's politically charged forestry climate, helicopter logging offers many advantages. Road builing can be curtailed or eliminated in many slaes. Steep slopes that were difficult and unsightly to log can be handled easily Commercial thinning and selective logging can now be considered. In fact, we see a time in which helicopters will lift entire trees from a falling area, and limbs and foliage will be completely utilized.

Since our first mid-sized Logger units were produced, Isolair has been asked to produce larger and smaller grapples. On the large end of the spectrum, our 6000-25 is well suited for heavy lifters such as the S-64 and Mi26. At one site in British Columbia, our 6000-11 produced over 350,000 lbs (158,900 kg) per hour. A 6000-25 is now in use and is expected to produce an even higher volume. Operators have reported increased aircraft utilization of up to 40%.On the smaller end, we have users doing slash clean-up profitably with the 6000-1 and a MD 500.

The science of modern helicopter logging has just begun and we, at Isolair, are proud to play a significant role. As custom manufacturers, we welcome your inquiries. Many of our best products have sprung from operator requests and we are always happy to work with you to develop the helicopter accessories you need to remain productive and profitable.
