Hydraulic System Redesign Cuts Fuel Costs

The agricultural market continues to demand mobile equipment that is both more powerful and more efficient. In response to this trend, a manufacturer of sugarcane harvesters began redesigning much of their equipment. Hydraulic systems for these machines typically use gear pumps for powering hydraulic systems. Although gear pumps are low cost, compact, and reliable, they are not as efficient as other types of pumps.

This presented an opportunity to increase machine efficiency and productivity—a combination that can substantially reduce fuel consumption. The goal was at least 10% to make their product more attractive to end-users. The OEM consulted with Parker’s Global Mobile Systems (GMS) team to create a new hydraulic system that would meet its new performance goals.

Parker’s P1 series variable-displacement, axial-piston pumps for open-circuit mobile applications offer compact, quiet and efficient, performance and can deliver a continuous operating pressure to 280 bar (4,060 psi).

Redesign Reduces System Complexity

GMS completely restructured the hydraulic system by switching to a variable-displacement open-circuit solution, using P1 Series pumps with Electronic Displacement Control (EDC) and F12 Series bent-axis piston motors. Parker’s P1 variable-displacement pumps have maximum displacement of 140 cc/rev (8.5 in.3/rev) and maximum flow of 278 lpm (73 gpm) at a max speed of 2,000 rpm. Maximum operating pressure is 280 bar (4,000 psi).

New Komatsu PC2000-11 excavator gets power boost for loading 200-ton trucks

Komatsu’s new PC2000-11 excavator is designed to load 70- to 200-ton rigid-frame dump trucks faster than its predecessor, boosting productivity up to 12 percent.

To achieve the performance increase, Komatsu gave the new hydraulic excavator a 9 percent increase in power over the PC2000-8, for a total of 1,046 net horsepower, and added a new engine-pump control. The hydraulic system automatically adjusts flow to operating conditions. In heavy-lift mode, the boom attains 10 percent more lifting force. New electronic proportional control valves in the hydraulic system also help increase work speed, according to Komatsu.

The company says it simplified the excavator’s power module, including the engine, hydraulic pumps, cooling package and PTO, to reduce noise and make it easier to access and maintain its major components.

KomVision system that provides a 360-degree bird’s eye view of the work area comes standard, along with the system’s 10.4-inch touchscreen monitor.

The PC2000-11’s specialty is stripping overburden, loading coal and shot rock, the company says. The company gave the boom stronger, thicker plates and castings and strengthened track and center frames. Carrier rollers are larger, and seals have been improved, the company says.

The engine achieves Tier 4 Final emissions compliance with no diesel exhaust fluid or selective catalytic reduction, instead relying on Komatsu dual diesel particulate filters. The engine also features auto-idle and auto-idle-shutdown to conserve fuel.

Tackling the power and acceleration challenges of EEDI

Turbocharger systems and strategies are being used to both reduce the installed power on ships and to overcome the acceleration challenges that reduced power requirements can bring

As the energy efficiency challenges on shipping escalate, more sophisticated measures for reducing emissions are coming into play. The turbocharger has a role on both improving engine efficiency and in recovering energy potentially wasted through heat.

Mitsui Engineering & Shipbuilding first developed its turbo hydraulic system (THS) to recover waste heat from turbochargers in 2008. The first engine with THS was delivered in 2014 and the company has since delivered the system for 19 sets of engines.

While many waste heat recovery systems aim to return recovered heat energy in the form of electrical power generation, the idea behind THS is to reduce fuel consumption by assisting engine rotation through the use of hydraulic technology. The main circuit consists of hydraulic pumps connected to the shaft end of the turbocharger by a reduction gear. The high-pressure oil pressurised by the pumps is delivered to a hydraulic motor directly connected to the engine crank shaft. Having driven the motor, the hydraulic oil is then returned to the pumps to be pressurised again.

According to tests on Mitsui’s test engine and at shop trial on commercial engines, THS delivers a fuel oil consumption cut of up to 3% without increasing NOx emissions.

The transformation of Terex

Terex was created by acquisitions. Its genesis can be traced back to the old General Motors off-highway truck division based in Motherwell, which still exists today, albeit under Volvo ownership. But just about every brand within the group has been bought rather than created.

After it listed on the New York Stock Exchange in 1991 Terex embarked on perhaps the most sustained acquisitions spree that the construction machinery sector has seen.

At that time the company consisted of not much more than the off-highway truck division in Motherwell, along with Unit Rig, Fruehauf Trailer and Koehring Cranes in the USA.

Driven by Ron DeFeo, who joined from Case in 1992 and took over as president the following year, Terex spent the next 10 years taking over Clark Material Handling, O&K Mining, Simon, PPM mobile cranes (including P&H and Italian manufacturer Bendini), American Crane, Peiner and Comedil tower cranes, Fantuzzi, Noell, Franna, Fermec, Benford, Powerscreen, Cedar Rapids, Finlay, Atlas Weyhausen, Schaeff, Fuchs, Jacques, CMI and Bid-Well.

In 2002 came two significant acquisitions that changed Terex: Genie (aerial work platforms) and Demag (more cranes). Unlike previous acquisitions these were not distressed or niche companies but major players in their sectors.

Until now, the Terex model had been buying struggling businesses, stripping out cost and trying to rebuild something out of them. Terex was the Poundworld plant firm, piling high and selling cheap. Its adverts proclaimed that you could buy three Terex cranes for the price of two competitors. While German and Japanese manufacturers promoted their technological superiority and bullet-proof reliability, Terex’s slogan was ‘Simple, available and cost-effective’. They aimed to disrupt the markets in which they operated, and often succeeded.

The addition of Demag, and to a lesser extent Genie, changed this. Terex acquired the Demag mobile crane business when the giant Mannesmann industrial conglomerate was taken apart by Vodafone and Siemens. Demag cranes were more technologically advanced than most. Terex had joined the big league, no longer making just rough terrains and truck cranes – “commodity products”, DeFeo and Filipov called them – but now all terrain and heavy-duty crawler cranes, both highly engineered products.

And if Demag (along with Schaeff and Fuchs, acquired the same year) taught Terex to think like the Germans, Genie taught it to think like the Japanese, introducing Terex to the Toyota Production System management philosophy.

By now laden with debt, it was time to take stock and digest, and the acquisitions slowed.

Then came the global crash in 2008 that reduced Terex’s annual revenues from US$8bn to less than US$4bn and saw it plunge to a loss of nearly US$400m in 2008.

Time for a new strategy: diversification from construction equipment into industrial machinery. It bought the factory crane and port equipment business Demag Cranes AG (initially 82% in 2011, then all of it in 2012). This had originally been part of the Mannesmann group along with Demag Mobile Cranes but by this stage was wholly unconnected except for a common brand name.

Morbark launches new Rayco T415 forestry machine

Morbark is debuting the new Rayco T415 Forestry Machine.

Designed for land-clearing companies, construction companies, pipeline contractors, utility contractors and real estate developers, the T415 allows customers to change between a Predator forestry mower/mulcher head and a Hydra Stumper stump cutter attachment.

“The T415 forestry machine is designed for large-scale land-clearing contractors,” said J.R. Bowling, Rayco Manufacturing’s mulcher specialist. “It’s a lot of cutting power in a very nimble package.”

Powered by a 415 hp Cat C9.3B Diesel Tier 4 Final engine, the T415 boasts a closed-loop hydrostatic system to power the mulcher or cutter head, sending 530 litres per min to the attachment’s drive motors.

The hydraulic output is power-optimized to match the engine’s power curve, keeping the mulcher or stumper rpm constant, even under load for a finer mulched product with fewer passes.

As the engine rpm pulls down under load, pump displacement increases to maintain the 530 litres per minute flow. The operator feels more power at the cutter head over a broader engine rpm band.

Predator mulcher head
For mowing/mulching applications, the Predator mulcher head has a 232-cm cutting width, and is powered by a pair of variable displacement drive motors.

The Predator mulcher head is equipped with 49 single-bolt teeth, including end teeth with extra carbide to power through anything its way. The mulching head also has a synchronous drive belt for low maintenance and long wear life and slotted mounting lugs to follow terrain with minimal machine stress. A manually adjustable tree catcher and hydraulic debris flap is standard.

The Hydra Stumper head muscles through stumps with its 122-cm diameter by 7.6 cm thick cutter wheel equipped with 56 Monster Tooth cutter tools. The cutting range reaches 2.74 metres wide, 2.69 metres high and 117 cm deep.

Troubleshooting Challenge: Shaft Seal Fails on Pressure-Compensated Pump

A simple 2,000-psi hydraulic system was designed and installed to run a conveyor in a hog-processing plant (see schematic). Two belt conveyors at a vertical angle to each other create a V shape, with about a 12-in. gap at the bottom and about a 30-in. gap at the top. A flat floor at the bottom of the conveyor slopes down from the entrance. Hogs travel down single file into the conveyor. As they enter the conveyor, the sloping floor causes the hogs to be wedged in and carried to where they are dispatched, and processing begins.

The new system developed a problem with the C-face mounted pump shaft seal failing after six weeks or so. The seal lip with a garter spring was pushed out. The maintenance crew replaced the seal and was told by the power-unit builder that this type of failure was normally due to excessive pump case pressure. The crew installed a standard 0- to 300-psi pressure gauge teed into the case line to monitor case pressure.

They observed it for several hours, then every day for a week or two. They noticed that when the pump compensated each time the conveyor was stopped, the pressure would spike between 10 and 15 psi but then only read about 5 to 8 psi. When the directional valve was shifted to run the system, the pressure would drop even lower.

The pump shaft seal failed again five weeks later. The power-unit builder said case pressures this low shouldn’t cause these failures, but they did not know what could be causing the failures.

Do you have any ideas?

Hitachi launches next in EX-7 mining excavator range -the EX1200-7

Hitachi has introduced the EX1200-7 excavator, which it ways will provide increased efficiency, reliability and durability for customers. The excavator, which is available in North and South America, is the third machine in Hitachi’s new EX-7 series lineup, following the recent launch of the EX2600-7 and EX5600-7. “Available in a backhoe or shovel configuration, the EX1200-7 is our smallest mining excavator and also serves as a crossover machine for construction customers,” said Brian Mace, Mining Product Marketing & Applications Manager, Hitachi Construction Machinery – Americas. “This versatile machine delivers an astounding combination of power and the latest technologies you need to get the job done, whether its large-scale excavation or mining.”

Thanks to Hitachi’s Fuel Consumption Optimization (FCO) technologies, the EX1200-7 improves total fuel economy by 6% as compared to the previous model (the EX1200-6) through engine and hydraulic system improvements. The EX1200-7 features a fuel-efficient Cummins EPA Final Tier 4 engine with DEF. For non-regulated countries, a Cummins engine featuring fuel-calibration optimisation settings helps contribute to improved efficiency. Additionally, when the machine is in neutral, auto-idle reduces engine speed to save on fuel consumption.

The new EX1200-7 also features a 4.5% increase in bucket capacity with a 7 m3 capacity. Equipped with optimised swing control, the new machine also has an improved hydraulic system with a flow regeneration valve to reduce power requirements from the hydraulic system and engine, lowering fuel consumption and improving pump life.

For reliable performance, the EX1200-7 undercarriage has three single-sided upper rollers on each side of the track frame that help maintain track shoe clearance and reduce debris build-up. Additionally, the boom and arm are welded, utilising a full-box section design to evenly distribute stress and provide ease of maintenance. The underslung low bend configuration of the front attachment hoses removes the need for clamping to help reduce chafing and increase reliability.

A new option with the machine is the auto-lubrication system for a bulk excavation front attachment, which supplies grease to the superstructure including bucket pins. The advanced system comes redesigned with a large capacity grease tank, new grease pump, in-line grease filter and breather with filter, resulting in a more reliable system with less downtime.

“The EX1200-7 design was created for optimal frame longevity to ensure the machine withstands the demands of any operation. With the cab resting on 6-point, support type, fluid-filled elastic mounts, the cab durability is significantly improved due to reduced shocks and vibrations. Likewise, a centre track frame delivers optimal stress dispersion in order to reduce the chance of failure in high-stress areas. An improved track link design also mitigates premature failure of the master pin while oil-filled idlers and rollers eliminate the need for daily lubrication.”
