Columbus Equipment Company unveils new Komatsu Hybrid Excavator
Columbus Equipment Company and Komatsu America Corp. announces the introduction of the Hybrid PC200LC-8 excavator into the North American market. With the new Hybrid PC200LC-8, Komatsu has raised the industry bar for hybrid technology and fuel savings, by delivering a machine with power and efficiency, while reducing environmental impact as compared to our standard model.
As a one of the world’s top construction equipment manufacturers, Komatsu’s goal is to meet increasing global environmental concerns through the development of innovative equipment designed to reduce environmental impact, including CO2 reduction. By developing a successful hybrid excavator in the largest construction machine segment (20-22 ton), Komatsu’s green technology will have a substantial impact on saving fuel and reducing green house emissions.
Powered by the Komatsu Hybrid System, the Hybrid PC200LC-8 uses a newly developed electric swing motor, power generator motor, capacitor and diesel engine. Komatsu developed its revolutionary hybrid system to work on the principle of swing energy regeneration and energy storage using the Komatsu Ultra Capacitor system. Komatsu’s Ultra Capacitors provide fast energy storage and instantaneous power transmission.
The kinetic energy generated during the swing braking phase is converted to electricity which is sent through an inverter and then captured by the Ultra Capacitor. This captured energy is then discharged very quickly for upper structure rotation and to assist the engine as commanded by the hybrid controller when accelerating under work load conditions.
In tests comparing the standard PC200LC-8 hydraulic excavator to the Hybrid PC200LC-8, the hybrid model reduced fuel consumption by approximately 25-40%, depending on the application.
The new Hybrid Excavator will be working in and around the greater Cincinnati area for the next several months.

JCB Introduces the JCB 2065 RTS Excavator
Displayed in North America for the first time here at ICUEE, the new 8065 RTS (reduced tail swing) Excavator – launched earlier this year at Intermat – gives contractors and operators a more powerful, safer and versatile machine. Replacing the 8060, the new 8065 is JCB’s most productive six-ton machine ever.
JCB midi excavators are well known for their performance, controllability, serviceability and versatility. Like the 8055 launched late last year, the new 8065 model builds on these core strengths and also features a new cab for unrivalled operator comfort and visibility.
Powering the 8065 is a new 54.3hp, Tier III Isuzu Turbo engine. This engine, along with a near five-inch reduction of the machine’s tail swing, makes the 8065 even more productive when operating in confined spaces.
The new excavator also features a heavy-duty dipper to give improved bucket and dipper breakout forces. Its maximum dig depth of 14’3” and dump height of 14’0” constitute a class-leading digging range. The improved bucket breakouts increase the 8065’s productivity, and ultimately, the customer’s return on investment. The single-piece wraparound dipper design reduces the need for weld points, increasing durability, and the easily accessible dig-end hoses are routed through the kingpost, protecting it from damage. The 8065 also features a new counterweight design that has further reduced the tail swing to seven inches.
The 8065 incorporates an improved undercarriage structure which includes upgraded track motors. With powerful dozing capability, excellent tracking performance and two-speed tracking, peaking at 3.3 mph, the JCB boasts improved mobility and approximately 17,500 lbf of tractive effort.
By combining automotive levels of comfort and styling with innovative new excavator design features and technology, the JCB 8065 exemplifies the very best in cab environments — a feature that’s become the hallmark of JCB equipment. As seen on the 8055, the deluxe cab is isolated from the swing frame, forming an isolated pod structure with benefits in terms of decreased cab noise and vibrations. The cab also includes a high-backed suspension seat and easy-to-use pilot-operated controls that move with the operator for a more effective working position and all-day comfort. The unusually large cab features a large-fold back door and well-positioned grab rails for easy entry and exit from the machine. Air-conditioning comes standard.
Dual pilot controls and proportional auxiliary flow deliver precision control, including low-flow and high-flow functions which improve the machine’s versatility. Electronic throttle control with auto idle function improves fuel economy and ease of use, while load-sensing hydraulics guarantee efficient and safe use of all functions.
All service points are easily accessed for convenient daily and periodical checks. Serviceability is also enhanced by the longitudinal engine positioning, and service intervals are set at 500 hours. To maximize the machine’s earning potential, the 8065 is compatible with all existing JCB 8080 ZTS, 3CX and 4CX buckets along with a vast range of existing JCB attachments.
The new 8065 joins an unrivalled lineup of mini and midi excavators from JCB. From the ultra-compact 1,929 lbs Micro 8008 to the 18,960 pound 8080ZTS, JCB offers 10 models in total. This broad spread of excavators includes six full zero-tail swing (ZTS) machines and a number of reduced-tail swing models, offering JCB customers a choice of weights and specifications to match their requirements. The range also includes the popular 8008, the 8018 mini, along with the 8025ZTS, 8030ZTS, 8035ZTS, 8040ZTS, 8045ZTS and 8055ZTS.

Constructed in the company’s Rostock manufacturing facility, the MTC 78000 is one of the biggest offshore slewing cranes worldwide. With a maximum dynamic torque of 78,000 tonnes, the MTC 78000 is the most powerful machine within the extensive range of cranes and material handling machines offered by the Liebherr group of companies. Four units of the new heavy-lift crane have already been ordered to date.
Despite its size, the MTC 78000 has been designed as a slewing crane and is supported by traditional large diameter anti-friction bearings. With a weight of 70 tons, the swing ring has a diameter of approximately nine metres.
Some special challenges were involved in the onsite erection and assembly of the huge crane onto the heavy lift vessel OSA Goliath; planning the individual hoists so that the maximum permitted ground pressure of the pier was not exceeded, for example.
Two Liebherr LHM 600 mobile harbour cranes were used in tandem operation for the heavy duty lifts. Both cranes with their maximum load capacity of 208 tons each enabled parts weighing up to 400 tons to be mounted in tandem operation. The machines were equipped with the recently patented Liebherr “sycratronic” control system. This Dynamic Anti Collision System controls the simultaneous operation of the mobile harbour cranes, so ensuring best possible performance and protection for the cranes.
The assembly of the MTC 78000 required several spectacular heavy duty lifts. First, the slewing platform was mounted – at 370 tonnes, the heaviest of the components. Then, the machinery compartment with the drive components (approximately 240 tonnes), the mast lower section (about 250 tonnes) and the mast upper section (around 160 tonnes) of which the lowest point needed to be hoisted up to over 43 metres above the pier level.
The last step in the assembly process involved putting the boom in place. In a tandem hoist operation, the 87 metre-long boom was positioned with minute precision at the respective connection points enabling the boom to be pinned to the slewing platform on both sides. The sheer size of the pins required a specially developed hydraulic pinning machine.
The heavy lifting test of the large crane was carried out in the open sea with a 1,760 tonnes test weight – corresponding to 110% of the nominal load capacity. The test loads consisted of two water filled pontoons which were lifted out of the water and turned around.
After the successful test, the client, Handel Maritime S.A. could deliver the heavy load vessel OSA Goliath to its purchaser, the Mexican company Oceanografia. The OSA Goliath is one of the largest heavy load vessels worldwide and is being used for platform reconditioning, pipe laying and to set up offshore wind power plants.
Equipped with its new MTC 78000 heavy lift offshore crane, the OSA Goliath is scheduled to work in the Gulf of Mexico on behalf of the Mexican oil company Pemex over the next few years.
The MTC 78000 achieves a maximum lifting capacity of 1,600 tonnes at up to 35 metre radius. This corresponds to a maximum dynamic moment of 78,000 tonnes, the crane still being able to slew over 360°. At a maximum radius of 74 metres for the main hoist the crane achieves a lifting capacity of almost 530 tonnes. In addition to the main hoist, the MTC 78000 offers two auxiliary hoists with lifting capacities of up to 500 tonnes and 50 tonnes respectively.
The size of the MTC 78000, which is in response to customer requirements, represents a new dimension in product development for Liebherr.
