Installing Clamps And Mounts; I-Beam Clamp (Hpm-A) - Task Force Tips HEMISPHERE Instructions For Installation, Operation And Maintenance

4.0 INSTALLING CLAMPS AND MOUNTS

Monitor clamps and mounts installed on weak objects can become unstable causing an out of

control monitor resulting in injury or death. Choose stationary objects capable of safely supporting
monitor reaction force, torques, hose load, and vibration.
Working from an elevated position involves increased risk of injury or property damage due to

falling persons or equipment. To avoid fall or drop hazards:
The Hemisphere transportable monitor can be secured onto fixed mounts or to a backbone that can be attached to stationary objects
using a series of different clamp types. The clamps are designed to restrain loads from only one monitor per backbone.
Clamp onto structures able to safety support loads from nozzle reaction force and weight loading. Loading includes weight of the
monitor, inlet fittings, discharge fittings, nozzle, plus hose when charged with water.
Avoid clamping onto frangible materials like fireproofing, insulating layers, sheet metal, brickwork, eroded process pipes, or structurally
compromised objects. The most reliable object is one that has been load tested under actual operating conditions.

4.1 I-BEAM CLAMP (HPM-A)

Before attaching to an I-beam or other suitable object, the clamp must be configured to position the monitor in relation to the clamped
object. Plan the mounting position to give good clearance for the hose, room to operate the valve handle, and plenty of freedom to
point the monitor where needed.
To assemble the I-Beam Clamp:
1) Slide the fixed jaw and clamp arm assembly over each end of the backbone
with the angled faces of the jaws aligned opposite one another. Be sure the
fixed jaw and clamp arm assembly are past the detent ball on either end of the
backbone to prevent them from sliding off.
2) Position the fixed jaw and clamp arm assembly in the cross-holes far enough apart
to allow the mounting object to fit between. Secure with a cross-pin.
3) Position the cross-pin mount in the cross-hole best suited for the
monitor installation. Secure with a cross-pin.
4) Verify that all components are properly installed and secure
before installing on the mounting object.

• Use care when transporting, installing, and using the Hemisphere, its mounts, nozzle, and
hose from an elevated position
• Select mount locations where there is no need to lean out beyond the confines of safety
railings
• Wear proper fall protection gear as directed by the Authority Having Jurisdiction (AHJ)
• Avoid situations posing a drop hazard to persons below
