Precision control boosts productivity on Bobcat compact excavator

The Bobcat E55 compact excavator offers precision control of the boom, arm and bucket, which is critical in harsh operating environments such as Africa.

According to Bobcat Equipment South Africa Product Specialist Jan Stansfield, precision control and movement, delivered by means of exclusive control valve systems and torque-limiting pistons pumps that match force with demand, boost productivity.

With a maximum digging depth of 3.923mm, the Bobcat E55 is used mainly in the mining, construction and plant-hire sectors, and has various clamp-ready arm configurations available. The standard power arm offers maximum arm breakout force, while the optional long arm allows for added reach and dig depth.

Selectable auxiliary hydraulics allow for three flow rates to optimise the response of hydraulic attachments such as tilting buckets, clamps, grapples, hydraulic breakers and augers. Low flow is ideal for precise control and accurate angles, medium flow for placing and handling materials and maximum flow for peak hydraulic attachment performance.

The excavator’s attachments can be operated continuously without the operator having to press a button.

“The excavator controls allow operators to make fine, accurate movements with minimum effort and maximum comfort, which translates into precise results in less time and with less fatigue,” says Stansfield. A rocker-style thumb switch on the left joystick gives superior boom-swing control with better metering than foot pedals.

The switch on the right joystick provides perfect control of the connected attachment, while multi-function operations such as simultaneous swinging and travelling are made that much easier. The location of the boom swing and auxiliary control on the joystick means more comfortable floor space and foot room, which is a definite advantage on long and arduous projects.

Two-speed travel and the Dual Direction Detent system, which provides for continuous flow for attachments in either direction, help to boost productivity, while the ‘auto idle’ reduces fuel consumption when the operator needs to pause the operation. The ‘auto shift’ travel function moves the excavator out of high range and back automatically, allowing for optimal travel performance without the need to downshift manually.

The Bobcat E55’s in-track swing frame places the machine closer to the workface, making it ideal for confined spaces.

The X-frame undercarriage not only means superior ground clearance, but also improves performance in soft, loose and difficult conditions. Dirt and debris passes through the undercarriage easily, making for quick clean-up. The drive motors are placed safely within the track widths, protecting the assembly and improving machine agility in soft conditions. The recessed motor covers not only prevent potential damage, but increase uptime as well.

A machine shutdown protection feature, which tracks engine coolant temperature, engine oil pressure, hydraulic oil temperature, and other functions, increases uptime, while catastrophic engine failure can be prevented by complete machine shut down.

Swing castings and cylinders remain within the tracks when digging in an offset position.

Onboard diagnostics troubleshoots problems proactively and efficiently. Simple service access checkpoints mean that preventative maintenance can be carried out when required, further reducing operating costs.

In addition to a full range of excavators up to 75t, Bobcat Equipment South Africa and Goscor Earthmoving, both part of the Goscor Group, also offer skidsteers, front-end loaders, TLBs and road equipment such as graders and rollers as part of a comprehensive total-solution package for its customers’ diverse requirements.
