The three compact excavators are powered by all-new JCB by Kohler diesel engines, delivering 55 hp (41 kW) in the 14,770 lb. (6,700 kg) machine and 64 hp (48 kW) in the 18,700 lb. (8,482 kg) models.
JCB is gearing up for massive growth in the compact excavator market with the launch of an exciting new range of midis.
The first three machines being unveiled as part of the new line-up are the 67C-1 and 86C-1 conventional tail swing models and the 85Z-1 zero-tail swing excavator — all designed to grab a bigger share of a market which is expected to grow by at least 16 percent over the next four years.
Among the key features of all the new CTS and ZTS models are:
• 10 percent lower fuel consumption
• 30 degree tilting cab for excellent service access
• 500 hour greasing intervals
• No costly DPF
• 6 percent more spacious cab
• 11 percent extra visibility
• 100 percent steel bodywork for excellent durability
JCB’s Chief Innovation and Growth Officer Tim Burnhope said, “The compact excavator market is expected to increase to over 200,000 units by 2017 and with this fantastic new range, JCB is ready to seize the opportunities presented by such massive growth.
“We have undertaken the biggest benchmarking and customer evaluation exercise in JCB’s history to come up with a range that is truly world-beating on all fronts: performance, reliability, cost of ownership, safety, durability, comfort and serviceability.”
The 67C-1, 86C-1 and 85Z-1 will launch a completely new look for JCB compact excavators, with a revised H-design undercarriage, robust steel body panels, a spacious operator environment and Tier IV final engines that deliver increased efficiency and lower operating cost.
The three compact excavators are powered by all-new JCB by Kohler diesel engines, delivering 55 hp (41 kW) in the 14,770 lb. (6,700 kg) machine and 64 hp (48 kW) in the 18,700 lb. (8,482 kg) models. These engines, which use up to 10 percent less fuel than the previous models, conform to the U.S. EPA Tier IV Final emissions standards without any requirement for a diesel particulate filter (DPF), reducing cost and operating complexity for the customer and allowing improved engine packaging.
The engines drive Bosch Rexroth hydraulic valves and Nachi slew motors and track drives and incorporate an additional reduced loss hydraulic system. Operating with reduced back pressure, eliminating parasitic losses, the hydraulic system puts less demand on the engine, reducing fuel consumption. All hoses feature O-ring face seal technology and are color coded for rapid identification.
Safest by Far
The machines feature JCB’s 2Go hydraulic safety system, seen on the company’s larger JS excavators. In addition to the standard hydraulic cut-off that is activated by lifting the left hand lever pod, the operator is required to activate the hydraulic system through a button on the right-hand console. In addition the hydraulics can only be activated when the operator is seated and the seat belt is worn. This reduces the chance of operators working the hydraulic levers from outside the cab, improving safety on site.
The machines are available with a twin locking, factory-fitted quick coupler system, incorporating fail safe systems, which demands the attachments can only be de-coupled at ground level via a positive pressure boom safe system circuit, eliminating the unhooking of attachments in mid-air, increasing onsite safety.
Robust Digging Equipment
The three machines feature a sturdy kingpost design with widely spaced bearings to prevent wear. In addition, JCB compact excavators use a new graphite-based pin and bush design delivering 500 hour greasing intervals, for reduced daily maintenance and lower operating costs. The machines also will be available from the factory with a roto/tilt function installed ready for use with a number of rotating and tilting bucket mount systems.
The digging equipment has individual hydraulic piping for easy maintenance and hose replacement. Twin auxiliary circuits will be available and operators will be able to program individual hydraulic flow settings for attachments through the in-cab monitor, making it easier and faster to change between powered attachments such as breakers and grabs.
Comfortable Operator Environment
The sturdy JCB compact excavator cab, which is now built in-house, delivers 6 percent more space and 11 percent more visibility than on previous machines. Both the conventional and zero swing models share the same cab structure, featuring flat glazing all-round for ease of repair. A revised heating and ventilation system, with optional air conditioning, offers greatly improved airflow throughout the cab, improving operator comfort and rapidly clearing windscreens in colder months.
The ROPS/FOPS cab is available with optional FOGS guards at level 1 and level 2, while the large cab door sits within the counterweight slew area, even on the zero tail swing model. The machine features “auto idle” that can be set by the operator to activate after 2 to 30 seconds without using the levers. There also are two digging modes, including an ECO mode for maximum efficiency, or a heavy mode for increased productivity, tailoring the machine’s performance to the application.
The cab incorporates an ergonomic switch layout and a new full color LCD display screen, with an additional monitor for a rear view camera. There is plenty of in-cab storage and the machines come with a 12V phone charger and a cup holder.
Rapid Travel Capability
The compact excavators sit on an all-new H-pattern track frame, with an open design and sloping side frames for easy cleaning. The tracks, with longer frames, deliver improved strength and stability and both machines can be ordered with steel, rubber or road liner (GeoGrip) tracks. Tracking speeds have been increased from a maximum of 2.6 to 3.1 mph, allowing faster repositioning on site and cutting downtime.
The machines also benefit from a completely redesigned dozer blade and arms. The blade profile has been optimized for smooth material flow and there is no requirement for a strengthening weld on the rear, allowing easy cleaning of the machine. Blade edges are angled to prevent damage and a four-way tilt adjustable dozer will be available as an option, all controlled with an electro-hydraulic dozer control lever in the cab.
Reduced Ownership Costs
The JCB 67C-1, 86C-1 and 85Z-1 feature 100 percent pressed steel engine covers, delivering sturdy component protection and easy repair. The midi-excavators benefit from improvements in their SAE service and maintenance rating, due in part to the tilting cab and repositioned components. With lower fuel consumption and no requirement for daily greasing, ownership and operating costs will be reduced, according to the manufacturer.
The new JCB compact excavators have a cab structure that can be tilted by 30 degrees to allow access to hoses and hydraulic components, for repair and maintenance. JCB also has improved the grouping of components to reduce maintenance times. In addition the machines have removable side skirts and in-fill panels for maximum service access, along with improved access to the cooling pack.
Another feature for greater fuel economy is the engine rpm automatically drops below the idle speed when the operator’s arm console is lifted, also reducing noise levels.
