05-4 RT55 Rough Terrain Crane
SET-UP
1. Crane load ratings are based on the crane being leveled
and standing on a firm and uniform supporting surface.
2. Crane load ratings on tires depend on appropriate
inflation pressure and tire condition. Caution must be
exercised when increasing air pressures in tires.
Consult Operator’s Manual for precautions.
3. Use of jib is not permitted for pick-and-carry operations.
SET-UP
1. For pick-and-carry operations, boom must be centered over the front of the crane with
swing and brake lock engaged. Use minimum boom point height and keep load close to
ground surface. Travel must be on smooth level surface.
2. The load should be restrained from swinging. No on tire operation with jib erected.
OPERATION
1. CRANE LOAD RATINGS MUST NOT BE EXCEEDED. NO ATTEMPT TO TIP THE
CRANE TO DETERMINE ALLOWABLE LOADS.
2. When radius is between listed values, the smaller of the two listed load ratings shall be
used;
3. Do not operate at longer radii than those listed on the applicable Lift Chart as tipping can
occur without a load on the hook.
4. All telescopic sections must be extended synchronously.
5. Without outriggers, never maneuver the boom beyond listed load radii for applicable tires
used to ensure stability.
6. Creep speed is crane movement of less than 61 m (200ft) in 30-minutes period and not
exceeding 1.6 KM/H (1MPH).
