Hoisting Procedure; Stacking Procedure - Christie J Series User Manual

Section 2: Installation and Setup

2.4.3 Hoisting Procedure

This procedure applies to one or more projectors. To hoist a stack, first
stack 2 or 3 projectors according to the stacking procedure included in this
manual. Never stack or hoist more than 3 projectors together.
1. Remove the projection lens to prevent possible damage during hoisting.
See 5.2 Replacing the Projection
2. If the projector is inverted, retract the adjustable feet to prevent the
hoisting hardware from getting caught.
3. Attach a safety cable to each of the 2 eyebolts mounted on the bottom
of the projector.
NOTE: Add eyebolts (2) if non-inverted. When hoisting a non-
inverted projector or stack, add 2 safety eyebolts in the front and rear
threaded holes provided on the top of the projector. Ensure the eyebolts
have an adequate rating for the load. Secure safety cabling to both
eyebolts.
4. Attach the rigging hardware by securing your rigging
components to the appropriate rigging points. There are 8
sliding points provided on the bottom. Tighten the nut at
each required location to prevent sliding.
NOTES: 1) Use at least 4 rigging points for all hoisting.
2) Use straps, clamps or cabling with load capacity
adequate for the total projector weight. See
Section 7: Specifications. 3) Do not join the rigging
straps or cables to a common point, keep separated as
shown.
