fasteners.
5.1. Installing davitrac
The operator must first be protected from the risk of
falling before any installation work.
The davitrac crane may only be installed on Tractel
®
bases that are suitable for davitrac.
5.1.1. Setting up davitrac on its permanent bases
•
Install davitrac (M) (fig. 3.a) in a Tractel
®
base
•
Remove the boom articulation locking rod (L) (fig. 3.b)
and unlock the strut to unfold the davitrac boom
•
Unlock the boom transport locking system
•
Position the boom strut on the davitrac mast at its

mast
NOTE:
the davitrac mast may be equipped with
a variety of systems with a Tractel
®
davitrac bracket for
blocfor™ R - caRol™ - scafor™ R.
When only one system is installed, it must be installed
at the rear of the mast:
•
A scafor™ R or caRol™ hoist is placed in the high
position (fig. 4.a)
•
The blocfor™ R fall arrest device is in the low position
(fig. 4.b)
When several systems are installed, they must be
installed as follows:
•
A scafor™ R or caRol™ hoist is placed in the high
position at the rear of the mast (fig. 4.c)
