NOTE: If hook height exceeds 330 ft (100m), the number oftower sections above the uppermost tie-in location MUST be re-duced by 1 tower section.
* Lower the top climbing unit to the uppermost tie-in prior to oper-ating crane at maximum hook height.
Consult Morrow Equipment for specific information regardingdimensions, tie-in locations, reaction forces and slab openings.
NOTE: The tie-in assembly shown to the left is an example of atypical installation. Please note, however, that factors determin-ing the installation of tie-in assemblies may vary due to projectspecific criteria. Contact Morrow for more information.

NOTE: Capacities and line speeds indicated will vary depending on the amount of hoist rope installed. This crane model may be equipped with a hoist unit other than thatspecified in the data above. To verify, check the serial number of the crane and refer to the Pecco SK 355-20 Operation Manual for additional information.

Power supply: 3-phase 480 V, 60 Hz; 3-wire plus ground; no Neutral.480 V phase-phase, 277 V each phase to ground with 120° phase shift between phases.Service size: 250 Amperes (for 105 hp/78 kW AC hoist unit) or 300 Amperes (for 165 hp/122 kW AC hoist unit).
NOTES: 1. For electric power provided by an electric utility, do not use open Delta transformers.2. For electric power provided by a generator, the minimum generator size required is 350kW for 105 hp and 500kW for 165 hp. A properly sized generator is critical to the safe operation of the crane.
