POWER TRANSMISSION CONTROL
An ongine mounted three-stage torque convener dtives all machlnory compononlS. Speed and power output requlr&- mentfl Arlt ()t’)Yemad by engine RPM, which ls conlrnlM!d by Iha hand and/or foot throttle. Optional conve,ter·to·machlnery sprocket reuce are avaflable. Consult factory,
VICON CONTROL SYSTEM (OPTIONAL)
The exclusive VICON control ayalem enables stepless vart. able ape&O output from \WO controlled torQuo converters, driven by a primary power plant One c;onverter drives the load hoist and boom holsl machinery, the other tho swing and travel machinery. Torque •nd speed are variably con· trolled from two Independent power sources, without sllpplng clutches or brakes
Independent se1 of swing clutches with separate power train permits simultaneous operation of swing, travel, nnd boom hoist machinery.CLUTCH SHAFT: Double-disc clutch with a-ptece replaceable lrlction discs. Cams, pinions, and clutch components are antllrictlon bearing mounted.
ROTATING BED Single piece steel weldmenl wilh Integral machinery side frames, Jig bored to assure precision alignment.HOUSE ROLLERS-&: 4 Front, bushing mounted. 2 Rear, anlilricUon bearing mounted, HOOK AOLLERS-6: 2 Fronl. bushing mounted,4 Rear. bushing mounted.RING GEAR – ROLLER PATH: 1051Wi” diameter with 4\<111 lace, machined Internal-type teeth, bolted lo carbOdy.
POWER LOAD LOWERING (OPTIONAL)
VICON POWER LOWERING
Powar lowering ts an Integral pa,t ot the VtCON CONTROL SYSTEM option on the 4000W. This systom enables raising,holding, or controlled lowering of 1he load by mHmi of hoist converter variable torque output. Holst clutch remains In con· stant engagement, making transfer of lhe load from clutch 10 brake unnaceseory during normal Job cycle.
FULL-RANGE VICON POWER LOWERING
The toad hoist drive train Is driven In lhe down direction by a hydraulic motor through an oil-spray lubricated direct chain drive. Hydraullc pump Is driven by lhe main output shaft ol the primary power plant. Antifriction bea,ings are standard. Tho hoist clutch remolns engaged during lowering. with speed and braking controlled by the converter valve. The pewer load lowerlng control Is located on the load hoist conirol lever.
CLUTCH-AND-RETARDER POWER LOWERING This eevice la designed for heavy duty loed lowering with Modal 4000W tranes not equipped with the VICON conlrol system. A load loworlng cluteh on the main drive shall Interconnects a chain drlvo 10 lhe halal drum. Hydraullc retarder, with heat exchanoer, In 1he primary drive absorbs load energy. Clutch can be disengaoe<I to lower a load rapidly. wl1hOul stopping machinery drive ln1ln. The power load lowering control Is located near lhe load hoist control lever.
