Precision robotic welding ensures aquality weld every time. These weldsincrease rigidity, reduce internalstresses and enhance durability for the chassis and track roller frames.

Heavy-duty, X-shaped chassis design.Cat undercarriage components arepurposely oversized to offer heavy-dutyperformance and durability.

Strutted track links are sealed for longlife. Track rollers, carrier rollers andidlers are also sealed and lubricated forexcellent service life.

Steep track rollerframe design andelimination of aledge at the carbodyand roller framejuncture, reduces material build-up and makes digging out easier.

Standard idler guards and center track guides maintain track alignment.Optional sprocket guiding guards or full length track guiding guards are available for additional protectionon steep side slopes.

Smooth autoshifting two-speed travelmotors offer top travel speeds andplenty of pull on slopes or turns.

1 Long (L) fixed gauge undercarriagemaximizes stability and liftingcapacity. Long, wide and sturdyundercarriage offers a stable workplatform.

2 Long variable gauge (VG)undercarriage provides ease oftransport and a stable platform when working on a variety of sites.The wider stance of the variablegauge improves stability over the side for increased lifting. The increased stability also allowsfor larger buckets that can result inhigher production.

Select the right combination for the jobwith your Cat Dealer to help ensure topproduction from the start. Choose fromthree booms and four sticks, plus a wideselection of buckets and attachments.The 345B Series II offers a largecombination of reach and digging forcesfor optimum versatility.

Choose from a variety of work toolssuch as hammers, shears, rotators,grapples or crushers. Ask your CatDealer for information on attachmentsor special configurations.

Caterpillar excavator booms and sticksare built for performance and longservice life.

■ Castings and forgings are used at highstress areas such as boom nose, boomfoot, boom cylinder and stick foot.

■ Large, welded, box-section structureswith thick, multi-plate fabrications inhigh-stress areas.

■ Construction allows structures to flexand dissipate stresses.

■ All booms and sticks are stressrelieved to maximize fatigue life anddurability, while minimizing weightfor improved performance.

Reach and Special Applications Sticks:■ The R 4.8 m (15'9") stick gives the

largest working envelope and usesmedium buckets.

■ The R/SA 3.9 m (12'10") stick useshigher capacity buckets and is bestsuited to trenching, excavation andgeneral construction applications.

■ The R/SA 3.35 m (11'0") stick has atighter working envelope but uses thelargest buckets of the reach stickfamily.

The Reach Boom (R) 6.9 m (22'8")features an optimum design thatmaximizes digging envelopes withthree stick choices.

The Special Application Boom (SA) 6.9 m (22'8") is reinforced for continualheavy duty rock applications and isthe same length as the reach boom tomaximize digging envelopes. Two sticksare available for use with the SA boom.

Booms, Sticks and AttachmentsThe 345B Series II is designed with the flexibility to help deliver higher production andefficiency .

The Mass Excavator (M) Boom6.55 m (21'6") maximizes productivity.The M Boom, used with the M 3.0 m(9'10") stick, offers significantly higherdigging forces and allows the use oflarger buckets.
