1.0 Application

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.

1.1 Limitations

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).

Angle 30°

to 45°

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

2.0 System Requirements

2.1 Compatibility 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).

3.0 Installation and Use

3.1 Before Each Use

Before each use of this equipment, carefully inspect it according to section 5.0 of this manual.

3.2 Plan

Plan your emergency escape system and how it will be used before starting your work. Consider all factors that will affect your safety before, during, and after an escape. Consider the following when planning your system:

A. Anchorage: Select a rigid anchorage point to connect the Trolmatic™ that is capable of supporting at least 12 kN.

See section 2.3.

B. Descent Path And Landing Area Clearance: Your descent path must be unobstructed. The landing area must be clear

of obstructions to permit safe landing of the user. Failure to provide an unobstructed descent path and landing area may result in serious injury.

C. Testing The System: 3M™ recommends performing a test descent using a 75 kg weight. The descent speed should

be uniform and allowed to reach the landing area safely. Remember to log any descent height (including test descents) in the Descent Log on Page 15 so that the cumulative descent height data is available.

D. Sharp Edges: Avoid using this equipment where system components will be in contact with, or rub against, unprotected

sharp edges. If working with this equipment near sharp edges is unavoidable, cover the sharp edges with heavy pads.

E. After a Descent: See Figure 4 below. To retract the device's line, deploy the articulated part of the handle, and then turn

the handle counter-clockwise. The system is ready for another descent after it is fully retracted.

Deploy the articulated part of the handle. Turn handle counter-clockwise to retract device line.

Caution: When retracting the cable into the

Trolmatic™, the cable should always maintain tension so that it fits in the handle without any slack. A minimum of 2 kg tension on the cable is recommended when turning the handle. Keeping the AG300 connected to the Trolmatic™ along the cable guide during cable retraction will provide the required cable tension.

3.5 Sitting on Trolmatic™

See Figure 6 below. A full body harness is recommended for use with this device. First, disconnect from any fall arrest or restraint device (lanyard, SRL…) you may be connected on. This is to avoid that starting the evacuation and being stopped by the primary fall arrest device that you are connected to.

Connect your front D-ring to the captive carabiner of the carriage mast. If you don't have a front D-ring, connect any other D-ring(s) you may have on your harness to the captive carabiner, like D-rings on the side slings of derrick harnesses, for instance. Open the belt and close it around you. Then, disconnect yourself of any fall arrest or restraint device (lanyard, SRL…) you may be connected on. This is to avoid that you start the evacuation and are stopped by your primary fall arrest device that you forgot to disconnect. Sit down on the seat of the carriage while holding down the manual brake to keep the carriage in place.

3.6 Use

Check your descent path and landing area for obstructions before stepping off the structure. The device will allow you to descend at a rapid rate. Release the manual handle and step out of the structure to descend freely. Pull down on the manual handle to slow your descent. Do not grasp the guide cable while descending. When you are at the last 20% of your descent, pull down on the manual handle to slow your descent before reaching ground level. After landing, disconnect your front D-ring from the trolley, open the belt and exit the landing area.

4.0 Training

It is the responsibility of the user and owner of this equipment to be trained in its correct care and use. The user

4.1

and owner must be aware of the operating characteristics, application limits, and consequences of improper use of this equipment.

Warning: Training must be conducted without exposing the trainee to a fall hazard. Training should be repeated

on a periodic basis.

5.0 Inspection

A formal inspection of the Trolmatic™ and its connection to the structure shall be made at least every 12 months,

5.1

by a Competent Person. A formal inspection should be completed if the system parameters are changed, such as after a system is moved or re-rigged its anchorages are moved, the guide cable angle is changed, etc. Extreme working conditions or an installation that is permanently outside may require increasing the frequency of inspections. Inspect the Emergency Descent Device according to Sections 5.2 and 5.3. Record inspection results in the Inspection and Maintenance Log in Section 9.0.

5.2 Inspection Steps

Step 1 . Inspect the device for loose fasteners and bent or damaged parts.

Step 2. Inspect device housing for distortion, cracks, or other damage. Ensure that the top anchorage and crank handle

are not damaged or distorted.

Step 3. The device lifeline must pull out fully. Inspect the wire rope for cuts, kinks, broken wires, corrosion, or severely

worn areas.

Caution: When retracting the cable, it should always be in tension to fit the handle without any slack.

We recommend a minimum of 2 kg of tension on the cable when turning the handle to retract the cable.

Step 4. Device labels must be present and fully legible. See Section 8.0.

Step 5. Inspect for corrosion on the entire device.

Step 6. Inspect connecting hooks, quick link or carabiners for damage, corrosion, and general functionality.

Ste p 7. Inspect the Carriage for excessive wear. The carriage brake handle must move freely along the cable guide.

Inspect the captive carabiner on the carriage mast and ensure that it is in perfect operating condition.

Step 8. Inspect the guide cable. Inspect the wire rope for cuts, kinks, broken wires, corrosion, or severely worn areas.

If the guide cable is damaged do not use the system.

Step 9. Inspect each system component and subsystem according to manufacturer’s instructions.

Step 10. Record inspection results in Section 9.0.

5.3 If inspection reveals an unsafe or defective condition, remove the device from service and contact an authorized service

centre for repair. Servicing from an authorized service centre is also mandatory as soon as the cumulative descent height in the Descent Log reaches 1100 m. For example, after 22 descents of 50 m in height, the Trolmatic™ will need to be serviced by an authorized service centre, who will at least change the brake.

6.1 Maintenance

Periodically clean the exterior of the Emergency Descent Device with water and mild detergent.

Position the device so excess water can drain out. Clean labels as required. Clean device lifeline with water and mild detergent. Rinse and thoroughly air dry. Do not force dry with heat. An excessive build-up of dirt, paint, etc., may prevent the lifeline from retracting back into the device.

6.2 Storage

Store the Emergency Descent Device in a cool, dry and clean environment, as well as out of direct sunlight. Avoid areas where chemical or organic vapours may be present. Thoroughly inspect the Emergency Descent Device after extended storage. The Trolmatic™ should always be fully protected against damage and deterioration.

If permanently installed outside or in damp conditions, adequate protection should be provided: cover, shelter, etc...
