1. GLOSSARY

Breaking Strain: The average load at which a new component (for example: a cable or chain

assembly) will fail. The breaking strain is obtained by applying direct tension to a component at a uniform rate of speed, in a testing machine.

Chute: A series of linked chute sections that are used to convey debris.

Chute Hoist: An engineered device that has been designed specifically to raise, anchor,

and lower a chute. A chute hoist consists of a support frame and a winch apparatus. The support frame, with the winch apparatus removed, can also be referred to as a chute hoist.

Chute Sections: Modular conical tubes that can be linked together in series to form a chute.

Chute System: A suspended chute and the anchors (including chute hoists) that support it.

Design Factor: Also known as the “safety factor”, it is a product’s theoretical reserve

capacity. The design factor is calculated by dividing the Breaking Strain by the Working Load Limit. The design factor is generally expressed as a ratio, for example: 10 to 1, or 10:1.

Working Load Limit:

The maximum load which can be applied to the component, when the

component is new, or in “good as new” condition, and when the load is applied in-line, with respect to the centerline of the component. This term can be abbreviated to WLL.

5. THE CABLE ASSEMBLY

THE VITAL COMPONENT

Every Superchute are used to link one chute section to the next.

The cable assembly pair is the vital component of a chute section. Each pair supports the weight of the chute sections beneath. Therefore, the uppermost pairs on a suspended chute support more weight than cable assembly pairs located lower down on the chute.

Consequently, if your chute will mix Superchute assemblies, plan to put the sections with the older cable assemblies at the base of the chute. This action will put the stronger cable assemblies at the top of the chute, where they are most needed.

THE CABLE ASSEMBLY (continued)

NEW HEIGHT & WEIGHT LIMITS OF CHUTE SECTIONS

Over time changes have been made to the cable assembly. As well, new height and weight limits are in effect. Check the date stamp on every chute section to understand your new height

& weight limit:

a) If the chute section was manufactured in February 1999 or later, and is equipped with the original cable

assemblies, it can carry a maximum of 60 sections (200 feet, 60 meters) or 2000 lb. (900 kg) of chute,

whichever is reached first.2

b) If the chute section was manufactured between June 1996 and February 1999, and is equipped with the

original cable assemblies, it can carry a maximum of 30 sections (100 feet, 30 meters) or 1000 lb. (450 kg) of chute, whichever is reached first.3 If you would like to be able to build a taller chute (up to the limits described in “a)” above), contact the factory for retrofitting of the cable assemblies.

c) If the chute section was manufactured prior to June 1996, and is equipped with the

original cable assemblies, it can carry a maximum of 15 sections (50 feet, 15 meters) or 500 lb. (225 kg) of chute, whichever is reached first.4 The cable assemblies of these sections feature lightweight, metal alloy clips stamped with the words “KONG – BONAITI - ITALY” (shown on the right). The KONG clip is much weaker than the forged ones currently used. The three possible colors of the KONG clip are:

If you have chute sections equipped with cable assemblies that use KONG clips, and would like to be able to build a taller chute (up to the limits described in “a)” above), contact the factory for retrofitting of the cable assemblies.

THE GATE OF THE “KONG” CLIP MUST CLOSE FULLY. If the gate is not fully closed, its strength is greatly reduced. Oil the gate hinge and spring regularly. Discard cable assemblies whose clip gates do not spring shut.

The above information applies to new, undamaged cable assemblies working together in pairs. Abuse or wear and tear will reduce the strength of the cable assembly. If you are unsure of the strength of your cable assemblies, please call the Superchute

Notes:

As of June 1996 the month and year of manufacture have been branded into every chute section.

ATTACHMENT TO THE CHUTE WALL

Prior to installing a chute section, ensure that two cable assemblies are fastened securely to the chute wall.

Please note that Wraparound cable assemblies attached to the chute wall. This shipping method keeps the sections from shifting in transport.

Attach cable assemblies to the chute wall using the instructions shown below and on the next page (these instructions are included with every pair of packaged cable assemblies).

• A loosely attached U-Bolt could undo and cause the failure and collapse of the chute.

• A falling chute system can cause serious injury and death.

• Attach each cable assembly to the chute wall, per the diagram

enclosed with every cable assembly bag (see next page).

MAINTENANCE

Check the condition of the cable assemblies on each chute section regularly:

• Replace cable assemblies that show signs of wear.

• Replace cable assemblies that have been strained.

• Oil the clip’s gate hinge and spring regularly. The gate must spring closed.

• For forged clips, spare gate springs can be purchased from Superchute

• Replace damaged cable assemblies with new, authentic Superchute

• Always change the full cable assembly, not just a part of it.

• Keep a written register, with dates and signatures, of all maintenance operations: record and

identify chute sections whose cable assemblies have been upgraded (or downgraded). Engrave a code or date into the plastic chute wall adjacent the cable assembly, or attach a durable identifying tag to the cable assembly.

Discard The Entire Cable Assembly If Any Of The Following Conditions Are Discovered:

THE WIRE ROPE:

• There are 3 or more protruding broken wires within a 2 inch (5 cm) interval.

• There are broken wires near attached fittings.

• The wire rope has kinks, birdcages, twists, or other distortions.

• The wire rope has been stretched.

• The wire rope is corroded.

• The wire has been damaged by heat, as evidenced by discolored wires.

• The thimble is loose and rattles in cable eye.

• The pressed sleeve is cracked, loose, or damaged.

THE U-BOLT GROUP:

• The U-bolt is bent, cracked, or damaged. • Pieces are missing from the U-Bolt Group.

THE CABLE ASSEMBLY (continued)

CAUTION!

Certain factors can be abusive and lessen the load that the cable assembly (and by extension, the chute section) can withstand. Some examples are:

• twisting of the cable assembly

• disfigurement, deterioration by straining, usage, weathering, heat, and corrosion

• rapid application of load or jerking

• the application of excessive loads

Keep corrosive substances away from the cable assemblies, and do not weld near the chute system.

Some types of damage may not be visible to the eye. Consider the following example:

Incident: A blockage occurred in a tall chute. The blockage went unnoticed and workers

continued to introduce debris into the chute. The installers had calculated the weight of the unblocked chute to be 1500 lb. (680 kg).

Debris continued to accumulate in the chute until the blockage was finally discovered by the inattentive safety monitor. A crane was called in and the entire chute was lowered to the ground. The crane’s load indicator showed the total weight of the chute and blocked debris to be 15,000 lb. (6800 kg).

Upon inspection of the cable assemblies, no obvious signs of strain were noted. The chute sections were equipped with cable assembly pairs having a combined working load limit of 2000 lb. (900 kg). The breaking strain of the cable assembly pairs is 20,000 lb. (9000 kg).

Action: Although the cable assemblies showed no obvious sign of strain, the working

load limits were greatly exceeded. All the cable assemblies should be replaced.

Conclusion: If, during the course of your job, the working load limits of the cable assemblies

are accidentally exceeded, consult a structural engineer and the Superchute factory to determine whether the chute sections in that system must be refitted with new cable assemblies.

WARNING

6. SELECT AN INSTALLATION AREA

Choose the installation area carefully. A poor choice can create a hazardous chute system.

Use the following guidelines when choosing the site for your chute installation.

1) SAFETY OF THE PUBLIC: The chute should be located in an area far from the public. Always consider the consequences of a worst case scenario. For example:

• If the chute collapsed (due to a blockage that overloaded the cable assemblies) would it fall across a high traffic area, over a road, over a pedestrian walkway?

• If a worker tossed a brick into a top hopper or door section, but missed, what could be the consequence of the brick falling outside the chute?

• If a hole wore through the chute wall, and debris escaped from the chute, would the debris shower the public below?

2) SHELTER FROM THE WIND:

• Select an area that provides shelter from the PREVAILING wind.

• Building corners that protrude outwards tend to accelerate the wind.

Due to this effect, do not place the chute within 20 feet (6 meters) of a protruding building corner.

• Inset corners generally provide

excellent shelter from the wind. Whenever possible, install the chute in an inset corner (see sketch).

• The effect of wind on the chute is

discussed in Section 10: Installation, under the heading: “Wind & Restraint Issues”.

(continued)

3) ELECTROCUTION: Prevent electrocution by choosing an area that is free of electric cables. If cables are present, contact your local electrical authority before proceeding.

4) THE CHUTE MUST HANG VERTICALLY: To reduce the risk of a blockage, choose an area where the chute will hang vertically. Horizontal displacement of the chute must not exceed 20% of the chute’s height. See the sketch below.

If the chute does not hang vertically, debris will rub against the chute wall. This friction will cause the speed of the moving debris to decrease, possibly to the point where debris stops moving, thereby creating a blockage.

5) PROTRUSIONS THAT CONSTRICT THE CHUTE: Choose an area that will not force the chute to bend over balconies, ledges or any other kind of large structural protrusion that will constrict the chute. The next page provides further information on this subject.
