USE: The Man Rated 5-Piece Adjustable/Variable Offset Hoist System is designed to attach to a person in order to raise or lower
EN
them to a work space. The system has been designed and manufactured to comply with the requirements of ANSI A 359.1-1992
and CE. This instruction covers the Advanced Variable Offset Mast (Model 18000, 18040) which has a pulley offset range from 12
inches (30.5 cm) to 29 inches (73.7 cm). Lower masts and mast extensions are designed to function as the same component. A
maximum of two components may be combined, but must not exceed 90 inches (228.6 cm) in height. Combinations of three or
more components must be reviewed and approved by DBI-SALA. The Advanced Variable Offset Mast may be equipped with front
mounted and/or back mounted winches (A) and self retracting lifelines (SRLs). Figure 1. The Offset Mast (B) has a standard
anchor point (C1) with a variable capacity (depending on the offset pin position); and the additional 5000 lb. (22.2 kN) capacity
anchor point (C2) can be used for fall-arrest anchorage. A head mounted U-bracket (Pt#15651) is available to mount on this
anchor point (C2). Figure 2.

BEFORE USE:

• All anchor points, or mounting/setup locations for permanent or portable systems must be approved by a qualifi ed person.*
• Plan your work program before starting. Have the required people, equipment and procedures available to do the job.
• Always work in teams. One person being raised or lowered and the other pays out the line and reels it in.
• Wear appropriate protective gear, such as: a hard hat, safety glasses, protective shoes with slip resistant soles, heavy
gloves, protective clothing and a face mask.
• Winches and SRLs may not be mounted in the front position on lower masts or mast extensions. Rear mounting is allowed
at any point.
• All winch and SRL mounting parts and hardware must be supplied or approved by DBI-SALA.
• Securely anchor the winch before using.
• Use only an approved full body harness for the workers.
• Use only retractable lifelines or shock absorber with a maximum arrest force equal to or lower than the lowest rated
component of your system.
• Retractable devices or shock absorbers must be installed and used in accordance with the manufacturer's instructions.
• Masts must be used with bases or sleeves approved for use with the applicable mast offset.
• Upper masts must be used with an appropriately sized lower mast.
• Where required by regulation, each installation must be approved to all applicable standards by a qualifi ed person.*
• All equipment must be set up and operated under the supervison of a competent person** according to the manufacturer's
instructions.
• Modular components are labeled with the capacities and rating to which they were designed, tested, and manufactured. The
rating of any system is considered to be the rating of the lowest rated component in the system. Do not use equipment if
rating labels are damaged or illegible. New labels are available from DBI-SALA.
• Adjust the mast using the Pin Positions (PP) as noted in Step 10. Follow the maximum and minimum positions for the offset
that matches your situation. Pay close attention to the base in case the base rating capacities change for different settings
(offsets) of the Variable Offset Mast (e.g. pin position 4 must use base position 4).
• If overhead obstructions are in the way, adjust the screw on the gusset (V) to its collapsed position (no exposed threads). If
obstructions are in front of your mast (e.g. a wall near the workspace access point) adjust the screw on the gusset (V) to its
full length (maximum exposed threads).
• The system should be removed from the job site when no longer required.
*Qualifi ed Person: An individual with a recognized degree or professional certifi cate, and extensive knowledge and experience in
the subject fi eld, who is capable of design, analysis, evaluation, and specifi cation in the subject work, project, or product.
**Competent person: An individual who is knowledgeable of a manufacturer's recommendations, instructions and manufactured
components who is capable of identifying existing and predictable hazards in the proper selection, use and maintenance of fall
protection.
INSTALLATION:
Step 1. To set up the hoist base, lay out all parts on the ground as in Figure 3.
Step 2. Remove leg pins (D) and rotate leg tubes (E) in leg sleeves (F) from transport/storage position (G) to operating
position (H). Figure 3
NOTE: Leg assemblies must be in operating position (H) at all times when using the hoist.
Step 3. Insert leg sleeves (F) into base center section (I). The width of the base may be adjusted by selecting different holes (J)
in the leg sleeve to install pin (K). Figure 3
NOTE: Base must be pinned into position through the hole in both the center section and the leg sleeve (K) at all times when
using the hoist. Figure 4
Step 4. Tighten the tri-screws (L) after the desired width is obtained to remove play from the base. Figure 4
Step 5. Move the base into position over the opening. Adjust the base height and level using adjuster screw (M) and level
indicator (N). Figure 4
NOTE: Base must be level at all times when using the hoist.
Step 6. To set up the hoist mast assembly, insert the lower mast (O) into base sleeve (P). Figure 5
Step 7. Make sure the stop dog (Q) faces the front of the sleeve (P), and that the lower mast (O) rotates freely throughout its
range of rotation. Figure 5
Step 8. Lock the lower mast (O) into position by tightening the tri-screw (L). Do not over tighten as this may interfere with mast
rotation in a rescue situation. Figure 5
Step 9. Install the upper mast assembly (R). Make sure that the locating key (S) on the lower mast (O) completely engages the
key way slot (T) of the upper mast (R). Figure 5
Step 10. To avoid tipping the base when swinging the mast side to side, adjust the base according to the following:
• Determine the maximum operating offset of the Variable Offset Mast. See Figure 6. Pin Positions 1-4 (PP) regulate the Top
Pulley (TP) and Bottom Pulley (BP) offsets. The table in Figure 6 shows the maximum offset (MAX) and minimum offset
(MIN) for each pulley in all 4 pin positions. Maximum offset is determined when the adjustable gusset (V) is fully collapsed
(no visible threads). Minimum offset is determined when the adjustable gusset is fully extended. Note: In Figure 6 the
Variable Offset Mast is in Pin Position 1 with gusset fully extended.
• Adjust the base according to the positions diagram shown for the base (W) and match the Base Pin Position (BPP) setting
