1.0Application

The Trolmatic™ is designed for emergency personnel escape with automatically controlled speed of descent from an elevated structure. The Trolmatic™ is only available as a sloped descent model. The Trolmatic™ has to be attached to the carriage AG300 on which the user sits. The carriage is sliding on a guide cable and has a manual brake for docking. See Figure 1.

Warning: The Emergency Descent Device must not be used for fall protection.

1.1Limitations

The following application limitations must be considered before using this equipment

A.Capacity: This equipment is designed for use by one person with a combined weight (including tools, clothing, etc.) of 20 kg minimum to 136 kg maximum.

B.Descent: This equipment may not be used for vertical descents. This equipment may only be used as described in this manual.

C.Slope Angle of Guide Cable: The guide cable should have an angle of 30° to 45° from the ground (see Figure 2).

Figure 2 - Slope descent angle

D.Descent Speed The speed at which the user will be lowered when using Trolmatic™ increases with the weight of the user and with the slope of the guide cable. The maximum speed of descent (inclined speed) is 4 m/s but the usual speed,

with the average angle and average weight, is around 2.5 m/s.

For example, if the angle is 45° and the length of the cable guide is 100 m, the corresponding height is 70 m. An average speed of 2.5 m/s will lead to descend the inclined 100 m length / 70 m height in 40 seconds.

E.Hazardous Areas: Use of this equipment in hazardous areas may require additional precautions to reduce the possibility of injury to the user or damage to the equipment. Hazards may include, but are not limited to: high heat, caustic chemicals, corrosive environments, high voltage power lines, explosive or toxic gases, moving machinery, sharp edges...

F.Training: This equipment is intended to be installed and used by persons trained in its correct application and use.

G.Operating and Storage Temperature: -40°C to 60°C

2.0System Requirements

2.1Compatibility of Components

The Trolmatic™ is designed to be used with its carriage and a 12 mm diameter cable guide.

Substitutions or replacements made with non-approved components may jeopardize compatibility of equipment, and may affect the safety and reliability of the complete system.

2.2 Compatibility of Connectors

Connectors (hooks, carabiners, D-rings) must be capable of supporting at least 20 kN. Connectors must be compatible in size, shape, and strength. Non-compatible connectors may unintentionally disengage (roll-out). Roll-out occurs when interference between the connector and anchorage connector causes the hook or carabiner gate to unintentionally open and release. Self-locking snap hooks and carabiners must be used with this system to reduce the possibility of roll-out. Do not use connectors that will not completely close over the attachment element.

2.3 Anchorage Strength for Emergency Descent Device

The anchorage / structure used to suspend the Trolmatic™ must sustain static loads, applied along the axis of the device, of at least 12 kN. When more than one Trolmatic™ is attached to an anchorage, the strengths stated above must be multiplied by the number of descent devices attached to the anchorage. Anchorages used to support a guide cable must be sufficiently strong to withstand the forces generated in the guide cable by the descent. Recommended anchorage strength (including a safety factor of 2) for cable guide shall be 18.24 kN (4100 lbs). Guide cable tension should be between 89 daN (200 lbs) and 200 daN (450 lbs).

2.4 Guide Cable and Trolmatic™ Installation

A guide cable must be used with this equipment. See Figure 3. The guide cable installation must be designed by a Qualified Person. The carriage must be installed as shown, with the braking manual handle pointing to the landing area. The carriage housing shall not be removed. Insert the cable guide into the carriage trolley at an open end of the cable guide before completing connection of the cable to the structure. The angle at which the guide cable is secured, as well as the amount of slack in the guide cable, will affect the descent speed. The guide cable must be installed with sufficient slope and limited slack to ensure the user will reach the landing area in the event of an emergency descent. The guide cable and the anchorage point must support the weight of the user in a descent. The guide cable MUST be 12 mm diameter wire rope, galvanized or stainless steel. Bottom anchorage for the cable guide can be the 3M Pylon Anchor (ref : 7256000, but not CE-certified).

Failure to follow wire specifications will prevent the carriage from sliding and braking correctly and may even cause the carriage to become stuck during a descent. Connect the quick link of the Trolmatic™ cable end to the lowest bolt of the carriage trolley (see the closeup of Figure 3) and ensure that the quick link is firmly tightened.

The operation of the Trolmatic™ should be verified by performing a test descent in accordance with section 3.2c. 3M™ can supply guide cable and associated cable clamps and thimbles (see Section 7.0 for component specifications).
