4.4.2. Self-stabilising base

When used in combination with the davitrac self-stabilising base, the Davitrac™ jib crane may be used
as a temporary fall protection anchor point for one or two 330lb. (150 kg) operators in accordance
with ANSI Z359.18-2017 and CSA
•
fall arrest systems,
•
rescue lifting devices,
•
rope-suspended working devices.
In such a configuration, it may not be used simultaneously as an anchor point for lifting equipment.
In this configuration, when the anchoring head (ref. A, fig. 2, page 4) of the jib crane is in
position P1 (fig. 1, page 3) and its PPE anchor point is subjected to the maximum force in the
event of a fall, the maximum displacement, or deflection, of the anchor point is 2 3/8" (60 mm).
OR
With respect to the definition in paragraph "4.2
Double pulleys
configuration, only one operator can be connected to one of the anchor points on the articulation
plate (ref. I2, fig 2, page 4).
This self-supporting assembly may be used in narrow spaces with no bearing structure. The self-
stabilising base is made of aluminium and steel for a total weight of 116.8 lb. (53 kg) divided into 3
subassemblies. The self-stabilising base is width-adjustable, with 2 positions (see Table 1 page 16).

4.5. Recommendations for use

Under no circumstances may the floor mounted, wall mounted and clearance mural bases be
used as fall arrest anchor points when the Davitrac™ jib crane is installed inside one of them. It
is imperative that once the Davitrac™ jib crane is installed and locked into one of the mentioned
permanent bases, the only anchor points allowed are those on the Davitrac™ jib crane.
When the Davitrac™ jib crane is used in conjunction with the Davitrac™ self-stabilizing base:
•
It is strictly forbidden to move a load suspended from the Davitrac™ jib crane outside the inside
perimeter of the self-stabilizing base.
•
The Davitrac™ jib crane must not be rotated under any circumstances with loads between
330lb. and 1100lb. (150 kg and 500 kg) (fig. 8a, page 9).
