DBI SALA LAD-SAF Instrucciones Para El Usuario página 8

2.3 LOAD REQUIREMENTS FOR STRUCTURE AND BRACKET CONNECTIONS: The climbing structure to which
the LAD-SAF system is installed must be capable of supporting the loads imposed by the system. For calculation
®
purposes the required bracket load may be assumed to be distributed evenly between the number of rung
attachments. For example; the TB-1 top bracket is supplied with three rung connections. The load required for
each rung for a single user system is 1,125 lbs (5.0 kN) per rung (3,375 lbs [15.0 kN]/3).
A. TOP BRACKET: The top bracket connection loads include system pretension and forces associated with
arresting a fall. Load requirements for the top bracket vary depending on the number of users allowed
on the system at one time, top bracket model, and type of connection to the structure.
Top Bracket Connection Loads:
• One user on the system: 3,375 lbs (15.0 kN)
• Two users on the system: 4,350 lbs (19.3 kN)
• Three users on the system: 5,325 lbs (23.7 kN)
• Four users on the system: 6,300 lbs (28.0 kN)
B. BOTTOM BRACKET: The bottom bracket connection must be capable of supporting a system
pretension load of 750 lbs (3.3 kN) in the direction of loading.
2.4 LOAD REQUIREMENTS FOR D-RING ANCHORAGE: See Figure 8. The D-ring Anchorage is designed
for use with the DBI-SALA Force2
must be attached to a Lad-Saf
requirements.
CAPACITY: The D-ring anchorage is for use by persons with a combined weight (clothing, tools, etc.)
of no more than 310 lbs (141 kg). No more than one person may be connected to the D-ring at any
time.
APPLICATION: The D-ring anchorage must be used in accordance with local requirements for fall
arrest or rescue systems.
SWING FALLS: Swing falls occur when the anchorage point is not directly above the point where a
fall occurs. The force of striking an object in a swing fall may cause serious injury. See the instructions
provided with the energy absorbing lanyard for more information.
3.0 SYSTEM INSTALLATION
3.1 This LAD-SAF system is designed for easy installation onto a ladder with a rung spacing of 11.024 in.
®
(280 mm). The basic procedure is:
Step 1. Install the top bracket
Step 2. Connect the cable to the top bracket
Step 3. Install the cable guides
Planning the installation can minimize the amount of time on the ladder and improve safety.
Use caution when installing LAD-SAF
WARNING:
including safety glasses and steel-toed shoes. Use personal fall arrest or restraint systems when
exposed to a fall hazard. Use caution when installing LAD-SAF
LAD-SAF cables are conductive. Do not connect to a partially installed LAD-SAF
