Bobcat E63 Becomes Second Largest Excavator in Line

By Frank Raczon, Senior Editor | September 4, 2013

The Bobcat E63 Compact Tail Swing excavator joins the company’s M-Series lineup with improvements in joystick controls, lift capacity, arm and bucket forces, and drive performance.

Replacing the E60, the E63 becomes the second-largest machine in Bobcat’s compact excavator family. The 6.3-metric-ton excavator features a number of operator conveniences including a blade float, multi-function joysticks, a color instrumentation panel, and an auto-shift drive system.

At an operating weight of 13,779 pounds, the E63’s horsepower has increased 13.5 percent to 59.4 horsepower with a diesel engine that is Tier 4-Final. The engine has a high-pressure common-rail fuel injection system, and a DOC and DPF.

Compared to the previous E60, the E63’s upper structure is shifted rearward on the undercarriage to increase efficiency, according to the company. The E63’s 11.6 inches of tail swing overhang enhances over-the-side lifting performance without increasing the machine’s overall weight. This additional tail swing also improves the E63’s slew performance when working on side slopes.

The E63 incorporates fingertip boom swing and auxiliary hydraulic functions. This not only improves multi-function capabilities, but also gives the operator more floor space. Independent boom swing control on the joysticks allows operators to more easily position the work group for offset digging. Selectable auxiliary flow rates and the detent (continuous flow) mode allow for more precise attachment performance, Bobcat says.

A new multi-language, color panel resembles instrumentation found on larger earthmoving equipment and provides a quick visual of machine vital functions. The home screen displays fuel level, coolant temperature, day/time, throttle position and engine rpm. Operators can select auxiliary hydraulic flow modes and rates from the panel. For increased security, an integrated password protection system may be used to help prevent theft.

A new blade float feature gives operators the versatility to grade, level or backfill material. The E63’s blade height is 16.1 inches—a 21 percent increase compared to the previous E60 model.

The E63’s hydraulic system offers 5,767 lb.-ft. of arm force. Engineered to dig to depths of 13 feet 6 inches, bucket force has increased to 9,731 lb.-ft. The E63 comes standard with Auto-Shift travel, which shifts the excavator into low range and back to high range automatically as the drive load subsides. Operators receive travel performance without having to manually downshift. Auto-Shift increases travel performance on demand, allowing operators to focus on the direction and speed.

New boom cylinder guards protect the boom cylinder when the excavator is digging. Four convenient tie-down points are integrated into the undercarriage to simplify trailer loading for transport. Extended grease intervals on the E63 work group minimize maintenance requirements, according to the company.
