Don't Let Heights Get You Down — Canadian Air-Crane can transport your construction projects to the top.

Patented "Anti-Rotation" Rigging System*

The ability to secure a tower or tower sections during installation can mean the difference between a quick job and possibly destroying the tower and cement foundation. Canadian Air-Crane's patented "anti-rotation" rigging system enables us to keep loads from spinning independently of the helicopter.

The anti-rotation device allows for precision control over minute movements of the load to set the base quickly and safely over the bolt stubs and minimize damage to bolt threads. The anti-rotation device consists of a 6 foot (2 meter) spreader bar suspended with the 25,000 pound (~11,340 kg) capacity winch and a "locking ring" with several catch points around the ring to lock the cargo into facing any major azimuth. The locking ring is secured to the helicopter through four hard points on the fuselage.

Ski Lifts:

Speed and efficiency are vital when transporting and installing ski lift towers. Our Erickson S-64 Aircrane is known for its impressive lift capacity - even at high elevations. With decades of experience in the industry, remarkable piloting skill, massive lift capacity, and quick, precise placement, Canadian Air-Crane's average time per lift is as low as seven minutes.

We can transport an entire tower/cross-arm structure up to the set site and keep it stationary and level while workmen accomplish the bolt-down. When altitude and temperature restrict the helicopter's lift capacity, our operations team can assist in the design and planning process to separate the towers into safe working loads that can be reassembled efficiently and securely at the set site.

Tramways:

Canadian Air-Crane participated in the installation of the Mt. Roberts Tramway, which stretches 1,800 feet (~549 m) and weighs more than 1,000 tons. The tramway is cantilevered off a cliff face near the top of the mountain. In some areas, the overall slope angle is greater than 60 degrees.

The treacherous terrain and remote locations of many tramways makes installation a challenge. The tremendous lift capacity of our Erickson S-64 Aircrane and our patented anti-rotation rigging system combine for the ideal construction crane system in areas that may be inaccessible to land-based construction teams.

Canadian Air-Crane has experience with tramway construction throughout the Pacific Northwest - from the Silver Mountain Gondola Tramway in Silver Valley, Idaho, to the Heavenly Valley Tramway near the southeast corner of Lake Tahoe, to the Mt. Roberts Tramway near Juneau, Alaska.
