Caterpillar Excavator Features (330C L UHD, 345B L II UHD, 365B L II UHD and 385B L UHD)

The Ultra-high demolition machines, 330C L UHD, 345B L II UHD, 365B L II UHD and 385B L UHD, are equipped with several features that are:

1- Integrated Tiltable Cab

The C-Series or B-Series tilt cabs are integrated into the upper-frame. The tilting mechanism of the cab is completely protected against debris, scrap, etc. The main advantage of this is that it does not increase the shipping height compared to the standard cab.

2- Boom Hook System

The front parts are equipped with a reliable and safe hook system between the boom foot and boom nose. Compared to the traditional pin-mounted joint, the hook system significantly reduces the time needed to change between the Ultra-High front parts and the short retrofit configuration, or the long-reach excavation configuration. In principle, the boom hook system consists of a hook system to pick up the front parts and a mechanical expander pin to secure these front parts onto the boom foot. The absence of any
hydraulic parts, as well as a full-length heavy-duty one-piece securing pin, ensures a safe and reliable operation.

3- Hydraulic Quick Disconnects

The hydraulic lines between boom foot and boom nose are fitted with hydraulic quick disconnects to even further reduce the time needed to change the front parts. Oil spillage and contamination is reduced through the quick disconnects flat-face design.

4- Dedicated Ultra-High Demolition Linkage

Because Ultra-High Demolition applications require a different working envelope than standard applications, a purpose-designed linkage is standard on the Ultra-High Demolition front parts.

Besides providing an optimized working envelope, this linkage also greatly improves controllability in nearly every position.

Caterpillar Excavator Features (385B UHD)

The 385B UHD is available in three different versions:

1- Long Reach Demolition

A22-meter version that can work with a 5-ton work tool (including quick coupler and mounting bracket ¨C center of gravity at maximum 1.5 m horizontally measured from stick nose). Unlike the other two versions, the 22-meter arrangement is a two-pieced front part (no fore boom). Excavation work is not allowed with this configuration.

2- Ultra-High Demolition

A36-meter version that can work with a 3-ton work tool (including quick coupler and mounting bracket ¨C center of gravity at maximum 1.5 m horizontally measured from stick nose).

3- Ultra-High Demolition

A 40-meter version, which works with a 2-ton work tool (including quick coupler and mounting bracket ¨C center of gravity at maximum 1.5 m horizontally measured from stick nose).

It is possible to convert a 36 m version to a 40 m version or vice-versa by swapping the fore boom.

5000 Series Caterpillar Excavators And Shovels Features

1- Cat Diesel Engines

Cat Diesel Engines provide the power, reliability and performance you can depend on.

2- Hydraulic Electronic Unit Injection (HEUI) and Electronic Unit Injection (EUI)

Hydraulic Electronic Unit Injection (HEUI) on the 5110B, and Electronic Unit Injection (EUI)
on the 5130B and 5230B electronically maintains fuel settings, provides automatic altitude and air filter restriction compensation, automatic variable timing, improved diagnostics and increased fuel efficiency.

3- Advanced Modular Cooling System (AMOCS)

Advanced Modular Cooling System (AMOCS) this patented cooling system used on the 5000 Series
promotes more efficient engine cooling, and is easy to service.

4- Proportional Priority Pressure Compensation hydraulic system

Proportional Priority Pressure Compensation hydraulic system delivers excellent controllability with full-powered response under all operating conditions.

5- Dedicated Swing Pumps

Dedicated Swing Pumps on the 5000 series ensures fast cycles, and consistent multi-function
implement response.

6- Automatic Lubrication System

Automatic Lubrication System eliminates a daily lubrication chore, automatically lubricates
the swing bearing, linkage, and undercarriage on regular intervals.

7- Vital Information Management System (VIMS)

Vital Information Management System (VIMS) on the 5130B and 5230B monitors all vital machine
functions, and keeps the operator advised on current machine conditions. VIMS reduces downtime and allows service personnel easy access to data for fast accurate diagnosis.

8- Electronic Monitoring System III (EMS III)

Electronic Monitoring System III (EMS III) on the 5110B monitors machine functions. The EMS III ensures that the engine and hydraulic system are perfectly matched to the operator's
demand for the most efficient power transfer possible, it also keeps the operator advised on current machine conditions.

9- Durable Structures

Durable Structures are a key component in the 5000 Series. Large castings eliminate welds in
high stress areas. Boom and sticks are thermally stress relieved to increase life. Boom and stick castings provide improved visibility over competitive designs. Penetrating, deep, beveled welds and rugged box section construction add to the machine's durability.

10- Service Access

Service Access is a priority on all 5000 Series machines. Platforms, walkways and hinged doors provide standing access to both sides of engine and pumps.

Caterpillar Excavator Machine Selection:

TRACKS VERSUS WHEELS

Features:

Tracks -

- Flotation
- Traction
- Maneuverability
- Severe underfoot
- Faster machine repositioning

Wheels -

- Mobility and speed
- No pavement damage
- Better stability with outriggers or dozers
- Leveling machine with outriggers
- Dozing capability

307-385

Unless the application calls for a lot of travel to, from, and around the job sites, a track-type excavator could be the better choice. Track-type excavators provide good traction and flotation in almost all kinds of underfoot conditions. Consistently good drawbar power provides excellent maneuverability. The tracked undercarriage also provides good overall
stability. If the job calls for frequent machine repositioning, a track-type excavator will provide better operating efficiency - where raising and lowering outriggers would take extra time.

Wheels (M313C-CM322C)

Looking for a highly versatile machine? A machine that can do more than mass excavation and trenching. Consider a Wheel Excavator.

A Wheel Excavator combines traditional excavator features such as 360¡ã swing, long reach, deep digging depth, high loading height, high digging forces and high lift capacities, with the mobility of a wheeled undercarriage. The rubber tires allow the excavator to travel paved roads, work in shopping malls, squares, parking lots and other paved areas without damaging the pavement. It's mobility allows fast independent travel between jobsites as well as on the jobsite giving you more job planning flexibility. The Wheel Excavator is the ideal tool for truck loading in tight quarters, undercutting concrete or asphalt, patching, shoulder work, curb and gutter repair, landscaping, spreading top soil, fine grading,
laying pipe, placing manholes or ditch cleaning.

A Wheel Excavator is also an ideal machine in material handling. It can load or unload trucks and carry loads around the job site. Stabilizers and a dozer blade can be pinned to the undercarriage increasing the machines stability during lifting.

Equip the Wheel Excavator with dedicated special attachments such as cab riser, material handling stick and boom. Add the additional hydraulic circuit option and your ready for a complete range of special tools. Ditch cleaning bucket, clamshell, grapples, hammers to name a few.

Caterpillar Wheel Excavators offer a load independent, load-sensing, flow distribution hydraulic system that gives the operator absolute precision and control no matter what the application.

Machine weight is the key to selecting a Wheel Excavator. Following are some additional factors that need to be considered.

Choose the proper boom and stick for your reach, digging depth and lifting requirements. Stability can be greatly enhanced by adding outriggers and/or a dozer blade. Additional hydraulic circuits can be added depending on your application and stick end attachments.

Acceptable Bucket/Stick Combinations

The following charts identify the acceptable bucket and stick combinations for Caterpillar Wheel Excavators and are based on stability. Minimum stability occurs with the linkage oriented over the side and positioned as shown in the visual. Dozer and/or stabilizers (if equipped) are raised and the bucket contains a full load. The longest stick is shown that has acceptable stability for each bucket. That stability is 1.1 moment ratio or better.
Once this stability factor is established, all shorter sticks are then acceptable with the listed bucket.


NOTE: Listed features may be standard on some models. Optional on others. Contact your Caterpillar Dealer for specific information.
