| clasp to allow the section to
be opened and stacked, like sheets of plywood.
The lay-flat design accommodates job-to-job
transport and storage needs. It is the preferred
design of roofers who use pick-up trucks to
transport materials. If the chute section has no
clasp, then it is a permanent tube. As a more
voluminous section, the permanent tube is less
desirable for meeting storage and transport
needs. |
| ....The cost of a chute system ranges from
$75 to $200 per section depending on the quality
and thickness of the plastic wall.Some companies
will stamp your company name into every section,
to advertise your firm and deter theft. |

| Installation |
| ....A small but typical plastic chute
system, 30 ft in length, weighs approximately 350
lb. Because the total weight of even a small
chute system is substantial, proper installation
is essential. |
|
....There are two aspects
to installing a chute system: Lifting it, and anchoring
it. Lifting the chute is the easy part. Anchoring can
present difficulties as roofs often lack built-in anchors
or structural members that can be used as anchors. For
this reason, chute systems are best installed using the
manufacturer's chute hoist.
| ....A properly designed chute hoist is able
to lift the chute & anchor it in place. As
well, the chute hoist should facilitate the
emptying of wheelbarrows, rubble buckets, and
loaders. Chute hoists generally use a manual
winch box, which is fast enough for chute
installation. They anchor the chute using counter
weights, or expansion anchors. Always check that
the chute hoist you purchase is engineered, and
has ample capacity for the heights you work at. |
| ....There are various models of chute hoist
available. Some lift and anchor 20 ft of chute,
while others can lift and anchor up to 200 ft of |
|
chute. The
cost of a chute hoist reflects the quality of its design,
construction, and the amount of chute it can lift. A
chute hoist capable of supporting 30ft of chute will cost
approx. $1000. The larger chute hoists (200 ft capacity)
cost approx. $10,000.
| ....Alternatively, the chute can be lifted
with a crane or a material hoist, and affixed to
structural members of the building. Do not use
parapet clamps to anchor your chute: Parapets
were never designed to support heavy loads, and
their strength can vary greatly from one building
to another. Trash chute systems are rapidly
becoming a part of the roofer's toolbox. The
trash chute speeds the roofer's work and keeps
the job site clean. Trash chutes are one more way
in which roofers can use a new tool to obtain a
competitive edge. RM |
