Aplicació

1. Finalitat: The Confined Space Davit is designed to work as part of a system to raise or lower a person or material to work in a confined space for entry, retrieval, fall arrest applications, and material handling. The Confined Space Davit is a modular design and allows multiple configurations with optional Davit Arms, Lower Mast Extensions, and Bases.
2. Límits d'aplicació: The FallTech Confined Space Davit is a dynamic anchorage system that will vary in its performance depending upon configured offset. Care should be taken to understand the capacity of the system and anchorage strength requirements.
3. Capacitat del sistema: The maximum capacity of the Confined Space Davit is one worker for confined space entry and egress, with the worker weighing no more than 3101bs (140kg) including clothing, tools, etc. For rescue applications, the Confined Space Davit has a maximum capacity of two workers with each worker weighing no more than 3101bs including clothing, tools, etc.
4. Davit Anchorage Strength: When using the FallTech Confined Space Davit with the 3-Piece Portable Base, the mounting surface must support 50001bs. When using the FallTech Confined Space Davit with any other base, please refer to the user instruction manual for the specific base.

Requisits del sistema

1. Compatibilitat de connectors: Connectors are considered to be compatible with connecting elements when they have been designed to work together in such a way that their sizes and shapes do not cause their gate mechanisms to inadvertently open regardless of how they become oriented. Contact FallTech if you have any questions about compatibility. Connectors must be compatible with the anchorage or other system components. Do not use equipment that is not compatible. Non-compatible connectors may unintentionally disengage. Connectors must be compatible in size, shape, and strength. Self-closing, self-locking snap hooks and carabiners are specified by OSHA and ANSI Z35g.12.
2. Compatibilitat dels components: Equipment is designed for use with approved components and subsystems only. Substitutions or replacements made with non-ANSI Z359 compliant components or subsystems may jeopardize compatibility of equipment and may affect the safety and reliability of the complete system, see Figure 1. Ensure compatibility between the connectors if non-FallTech components are used for fall protection.
3. Connectors: Only use self-locking snap hooks, rebar hooks, and carabiners with this equipment. Only use connectors that are suitable to each application. Ensure all connections are compatible in size, shape and strength. Do not use equipment that is not compatible. Visually ensure all connectors close and lock completely. Connectors (snap hooks, rebar hooks, and carabiners) are designed for use only as specified in this manual.

Instal·lació i ús

General Rescue Requirements: The equipment specified in this manual is designed to work as part of a system to help facilitate non-entry rescue and entry rescue from confined spaces.

• Confined spaces vary in size, shape, configuration, and hazard. The equipment/device(s) detailed in this manual may not be suitable for use during some permit-required confined space entries. Hazards such as entanglement, electric arc, engulfment, and general lift obstructions may interfere with safe rescue and cause greater harm to the entrant.
• All confined space entries should be planned whenever possible in such a manner that any foreseeable hazard is mitigated and non-entry rescue can be facilitated.
• In the case that non-entry rescue is not feasible, a rescue plan must be in place that provides rescuers with knowledge about the specific confined space hazards they may encounter during a rescue, training on appropriate rescue methods for the confined space they will be entering, and the correct equipment and PPE to perform the entry rescue. Please reference OSHA code CFR 1926.1211 and ANSI Z117.I-2016 for further details on employer responsibilities in preparing for both entry and non-entry rescue.

System Configurations for Non-Entry Rescue Methods: When entering a permit-required confined space, non-entry rescue is required unless retrieval equipment would increase the overall risk of entry or would not contribute to the rescue of the worker. Mechanical devices must be available to retrieve personnel from vertical type permit spaces more than 5 feet deep. When using mechanical devices for non-entry rescue, consideration must be given to the means of entry/egress, the mitigation of fall hazards and the method of emergency retrieval.
Single Line — Winch Only — Entry/Egress Using Ladder

1. When a single mechanical device is used for non-entry rescue into a confined space it serves only as backup to the worker’s primary entry/egress method. In most cases the primary means of entry/egress into a vertical confined space is a ladder. When using only a winch as the backup to the entrant’s primary means of entry and egress, the attendant should take care to keep the winch line taut to avoid any potential overload due to a fall event on the winch line. The winch is not a fall arrest device and must not be subjected to fall forces. The winch is for emergency retrieval only. See Figure 2. Single Line — 3-Way Only — Entry/Egress Using ladder
2. When a single mechanical device is used for non-entry rescue into a confined space it serves only as backup to the worker’s primary entry/egress method. In most cases the primary means of entry/egress into a vertical confined space is a ladder. When using an SRL-R only as a back up to the worker’s primary means of entry and egress the device cable will pay freely in and out of the housing as the entrant moves into the vertical confined space. In the event the entrant falls the SRL-R will arrest the fall and reduce fall forces applied to the body. The attendant may then engage the backup emergency retrieval winch to raise the entrant out of the confined space. The emergency retrieval winch is not to be used for ordinary entry/egress in and out of the confined space. See Figure 3.
3. Dual Line — Winch and SRD/Alternate PFAS – Entry/Egress Using Ladder When a confined space has an existing ladder but the attendant is unable to maintain a taut winch line as the entrant descends and ascends from the confined space, it is possible to use a regular SRD or Fall Arrestor Connector Subsystem (FACSS) to provide protection from impacting and overloading the winch during a fall event. In this case the PFAS provides fall protection as the worker freely moves vertically, and the winch provides backup as the emergency retrieval device from the confined space. See Figure 4.
4. Dual Line — Winch and 3-Way — Entry/Egress Using a Winch When no alternate method of entry/egress (such as a ladder) exists the confined space entrant will be suspended, raised and lowered with the winch line attached to a shoulder yoke or sternal D-Ring of a Full Body Harness. An SRL-R is then attached to the dorsal D-ring of the Full Body Harness to provide fall arrest and emergency retrieval. Suspended workers are required to have a backup system to their primary means of entry/egress that will limit fall forces to the body and provide emergency retrieval in the event of a winch malfunction. See Figure 5.

3pc Portable Base Assembly (Applies to both base sizes)

IMPORTANT

• Please see Table 2 in Appendix A for 3pc Portable Base compatibility. The davit base legs are shipped in a different orientation to optimize packaging and storage when not in use, Figure 15. To assemble, the legs must be rotated from the packed position to the proper orientation for use. On both legs, remove the detent pins as shown in Figure 16. Rotate the round tube of the leg to the use position, as shown in Figure 17. Align the holes of the round tubes and reinsert the detent pins, as shown in Figure 18.
• Before inserting the legs into the base center section, refer to the table in Figure 19 to match the Base Position with the Pin Position of the Davit Arm. To install the Davit Base Legs, ensure the red thumb screws are loosened (turn counter-clockwise). Insert the legs into the base center section and determine the offset your application requires; align the holes and insert the detent pins, Figure 20. Tighten the red thumb screws (clockwise) to ensure they are locked in place as shown in Figure 21.

Confined Space Davit System Assembly

• Place the Portable Base in the location suitable for the application. Insert the Lower Mast Extension, see Figure 22, into the Portable Base sleeve with the position limiting bolt toward the front of the base as shown in Figure 23.
• Lift the Davit Arm and place if onto the Lower Mast Extension, see Figure 24. Ensure the bolt on the Lower Mast Extension fits into the Davit Arm mating notch as shown in Figure 25.

Anivellació

• When using the Confined Space Davit System, the base must be level at all times with the legs pinned and tightened in place.
• To level of the davit, adjust each leg height until the bubble is centered in the bubble level, see Figure 26.

Fine Offset Adjustment

• The Confined Space Davit System is equipped with a fine adjustment screw to help ensure the anchor point is centered over the entry/egress location.
• To adjust, turn the fine adjustment screw to raise and lower the arm to the desired position, see Figure 27.

Winch/3-Way Installation

• Based on your application, attach the FallTech Davit Device Receiver Bracket to the davit using the provided detent pins.
• See Figure 28 for correct and Figure 29 for incorrect orientations of the Davit Receiver Bracket. DO NOT mount any device on the front of the lower mast.
• To attach a winch or 3-Way to the Davit Device Receiver Bracket, place the notch in the device side bracket over the bottom bar of the bracket as shown in Figure 30. Rotate to align the upper holes, see Figure 31. Insert the provided detent pin, see Figure 32.
