MODEL SPECIFIC INFORMATION
Crane Stability
The RT770E on rubber load charts have a minimum radius of
3 m (9.8 ft) with a load. Without a load, a radius of 2.5 m
(8.2 ft) is safe for 360° on rubber. A radius of less than 2.5 m
(8.2 ft) must be avoided on rubber because of backward
stability considerations.
Access Platform Hand Rail
Ensure that the hoist access platform hand rail (1)
(Figure 2-11) and step (2) (Fixed counterweight units only)
are in the travel configuration. Remove pins from hand rail
and rotate it down into the travel position, reinstall pins. Pull
