EXTERNAL AIR TRANSPORT BY CH-47 HELICOPTER
This work package describes how to prepare the scraper for external air transport by CH-47 helicopter, and how to
return machine to operational configuration after external air transport.
Due to weight restrictions, the tractor and scraper must be sectionalized (separated) to accomplish external air
transport. Selected components are also removed from the tractor to further reduce weight of the tractor. Once sep-
arated, tractor and scraper are each separately rigged with sling legs and lifted by CH-47 helicopter.
The level of disassembly required will depend on the CH-47 mission flight profile. Prior to sectionalization, this
mission flight profile must be determined. This will ensure machine is disassembled only to the degree required to
meet weight requirements.
Amount of fuel left in machine's fuel tank must comply with guidance from Military Traffic Management Com-
Assistance from two Unit Maintenance mechanics is required to prepare the machine for external air transport.
If operating machine without ROPS/FOPS, drive with extreme caution, at low idle, and in 1st gear or
reverse ONLY. Machine has no rollover/falling object protection without ROPS/FOPS. Failure to fol-
low this warning may cause injury or death to personnel or damage to equipment.
As part of this procedure, the ROPS/FOPS is removed from the tractor. Operation of the machine after assembly at
the work site may be required without the ROPS/FOPS, until the ROPS/FOPS is transported to the work site and
Use extreme caution when handling heavy parts. Provide adequate support and use assistance during
procedure. Ensure any lifting device used is in good condition and of suitable lift capacity. Keep clear of
heavy parts supported only by lifting device. Failure to follow this warning may result in death or injury
Many components that must be removed and installed during this procedure are very heavy. Use assistance, cau-
tion, and follow safe work practices when handling them.
Hitch and steering movement can reduce clearances suddenly and cause personnel injury. Always stop
engine BEFORE working in area of hitch link.
Throughout procedure, be aware of potential hazards when working around hitch. Do NOT work in area of hitch
link unless engine is shut down.
TOOLS AND EQUIPMENT
Tools and equipment required for sectionalization are stored in an ISU-60 shipping and storage container (Item 1,
Tools required to assemble machine after external air transport must be carried in the scraper's on-board BII tool-
box. This is because there may be a delay in the delivery of the container to the assembly site. After transport and
assembly of machine, stow tools and equipment in container.
