|
HYDRAULIC RESERVOIR |
|
184 gallons (670 L) capacity |
|
CONVEYOR |
|
Arc type hydraulically driven 36” (91cm) wide, center-guided belt, infinitely variable in speeds from 0 to 870 fpm (265 m/min) in either direction. Hydraulically transversely shiftable for precise spoil placement selection. An automatically-engaged anti-drift brake is provided on the shift mechanism. |
|
DIGGING CHAIN DRIVE |
|
The headshaft is driven from both sides by a two-stage roller chain arrangement directly behind a heavy duty differential, which is powered by a power shift transmission with integral three-element torque converter. Four digging chain speeds are available to suit varied digging conditions. Chain speeds: 1st gear-192 fpm (58.5 m/min); 2nd gear-256 fpm (78 m/min); 3rd gear-381 fpm 116 m/min); 4th gear-517 fpm (158 m/min). All shafts, chains and bearings are designed to accommodate the full output of the torque converter and transmission in the stall condition (approx. 2.3 times normal operation torque). Roller chain tension is adjustable for both stages with eccentric hubs. All drive chains and sprockets are fully enclosed and oil bath lubricated. |
|
DIGGING CHAIN |
|
Caterpillar style D-7 size digging chain for triple chain and D-8 size for single and double chain applications. Boom furnished with hydroadjusters to maintain proper chain adjustment. Rectangular steel cutter bar plates of varying widths and thicknesses to which tooth holders are welded to accept rotating, conical, carbide-tipped digging teeth. Plates are bolted to digging chain. 48" (122cm) diameter tailwheels with heavy-duty seals and bearings. Boom equipped with replaceable, abrasive-resistant wear plates on top and bottom. Top of boom equipped with carrier rollers to reduce chain drag and assist chain in shedding excavated material. |
|
CRAWLERS |
|
Caterpillar type D-7 size components with 30" (76cm) low profile double grouser shoes. Caterpillar® crawler idler/recoil assembly with double springs. Crawler rollers are oil filled and sealed. Each crawler assembly is removable to facilitate transport. |
|
CRAWLER DRIVE AND STEERING |
|
Infinitely variable hydrostatic/mechanical system for speeds from 0 to 1 mph (1.6 km/h). Separate hydrostatic transmission for each track. Tracks may be counter-rotated for good maneuverability. Easily adapted to automatic steering system, either laser or stringline. Steering is electric over hydraulic for excellent control. |
|
OPERATOR’S CAB |
|
Fully enclosed, pressurized with climate control. All machine controls within easy reach of the operator. Elevates hydraulically 44 inches (112cm) for increased operator visibility. Located on left hand side of the machine. |
|
DIGGING BOOM |
|
Various sizes of boom equipped depending on digging width selections:
• 14" through 18" (36 - 46cm): single chain arrangement
• 24" through 42" (46 - 107cm): double chain arrangement
• 32" through 54" (81 - 137cm): double chain arrangement
Boom can be sectionalized to adjust overall maximum digging depths to optimum length for maximum efficiency. |
|
