Advanced container handling technologies are making operations more efficient while reducing emissions and extending equipment lifecycles.

The Terex Brand, Fuchs, recently unveiled a new high-capacity material handler built specifically for the high production needs of scrap recycling operations and port applications in North America. According to Fuchs, the material handler offers outstanding lift capacity, a powerful but ultra-efficient engine, solid undercarriage for excellent stability and massive axles for high reliability. The model was conceptualized from customer requests and feedback.

Additionally, Fuchs has recently introduced a re-engineered operator's cab specially designed for purpose-built material handlers. Features include standard joystick steering, which improves machine responsiveness to operator commands, while large windows provide enhanced visibility of the operating area.

"Facilities running mega shredders who require a high-capacity, extremely efficient material handler with long reach will especially benefit from this new material handler model," said John Van Ruitenbeek, North American Business Line Director for Fuchs in a statement.

Set for delivery in August this year is crane spreader manufacturer Bromma's first order of six units of Automated Lashing Platforms (ALPs) for the Victoria International Container Terminal (VICT) in Melbourne, Australia. Extensive collaboration between Bromma, VICT and other parties has resulted automation of processes and communications with the crane automation, Terminal Operating System (TOS). The ALP will allow it to become an integrated part of the Neo-Panamax Ship-to-Shore (STS) crane movements.

The design of the new ALP, purported to a first in the industry, means one of the most dangerous jobs within a container terminal – that of human placement and removal of twistlocks from heavy suspended loads, will be eliminated. "The ALP was the missing piece in our ambition to achieve the safest, most automated terminal in the world," said Anders Dømmestrup, CEO of VICT in a statement.

The ALP has the capacity to handle 20, 40, 45 and twin 20-foot containers. During operations, it efficiently stores the twistlocks and under-deck pins within the unit for discharge and re-use when backloading an entire vessel bay on a 14,000-TEU vessel. The current system is tested and designed as a stand-alone unit that will sit in the back reach of the STS crane. Bromma is also planning to develop the ALP to be fully integrated to form a Crane Lashing Platform.

On the container handling front, Hyster's H1050-1150HD-CH series is one of the most advanced on the market, with the capacity to lift containers at 59 feet per minute (unladen) and 51 feet per minute (laden) and can lower at speeds of 98 feet per minute (unladen or laden).

The series provides up to 88,000 lbs. of lifting capacity and has been designed to reduce the time in the shop, and increase customer productivity. "When it comes time for service, the aluminum cover plates are easily removed using quick disconnect latches, providing access to all major components including the drivetrain and hydraulic system," explains Brett Schemerhorn, President of Big Trucks. "And with extended service intervals of 500 hours on major engine and drivetrain components, trucks remain in operation longer." Additionally, the optional automatic greasing system provides greasing for the chassis, the mast and the spreader, eliminating manual greasing of all greasing points throughout the truck.

The Hyster cab's structural design and curved windshield create all-around visibility, optimal for container stacking, and the sloped counterweight design allows for excellent rearward visibility. Advanced ergonomics help make the job easier for operators with power steering and lever controls, push-button parking break and auto throttle-up, as well as responsive, fully hydraulic brakes. Optional air-conditioning and soundproofing of the cab are additional features that can help create a quiet, relaxed working environment.

Hyster's model RS45-46 ReachStackers first came to market with Tier 4 Final engines in 2014. Hyster's Tier 4 Final powertrain technology utilizes Cummins cooled exhaust gas recirculation (EGR) and variable geometry turbocharging (VGT) in the engine along with a diesel oxidation catalyst (DOC) for particulate matter removal.

A selective catalytic reduction (SCR) based after treatment system was also added to achieve Tier 4 Final compliant NOx reduction levels. The injection of diesel exhaust fluid (DEF) into the exhaust stream in the decomposition reactor tube (DRT) reduces the NOx gases to harmless by-product. Advanced electronic control is used to ensure particulate matter is oxidized by a continuous process of passive regeneration.

In addition to these powertrain advances, Hyster has deployed technology to not only reduce emissions but also fuel consumption. "Using less fuel not only saves fossil fuels, but also results in a direct reduction of CO2/greenhouse gases and puts money back into the owner's pocket," says Schemerhorn.

Hyster trucks have seen up to a 20 percent reduction in fuel consumption during extensive testing compared to Tier 3 trucks, depending on rating and duty cycle due to design features that include on-demand hydraulics, on-demand cooling and automatic throttle-up.

The RS45-46 series also boasts an adjustable turning radius that reduces stress on the axle and improves tire life by reducing tire scrubbing. Oil-bathed wheel bearings are used to ensure bearings are constantly lubricated for long life under heavy-duty operating conditions.

In addition, the series features selectable operating modes, automatic throttle-up and idle management, which lowers engine RPM and reduces fuel usage and emissions by 20 to 30 percent. As well, the empty seat engine shutdown option with adjustable time delay shuts the engine down a few minutes after the operator leaves the seat of the truck, further reducing emissions.

"We only offer one powertrain, and worked very closely with the engine and transmission suppliers to ensure we have the best integration," says Schemerhorn. "The engine, frame and hydraulics are all designed to work together. That enables us to achieve higher productivity while delivering better fuel economy."

According to Schemerhorn, the emissions standards for the container handling power category are now 0.4g/kW-hr oxides of nitrogen (NOx) and 0.02 g/kW-hr particulate matter. As a result, current generation engines emit less than 5 percent of these emissions compared to 10 years ago.

He believes new technologies and innovations will result in continuously 'greener' high capacity material handling equipment. Alternative energy, hybrid technology and new materials used may spell future industry developments.

"But green technology can go further than the equipment," he says. "For instance, the Hyster plant at which the H1050-1150HD-CH container handler is produced along with all other port equipment for Hyster globally, was awarded an environmental award for sustainable, improved processes; improved energy use; reduced fuel usage; reduced necessity to repaint vehicles; and the 93 percent reduced emission of volatile organic compounds (VOCs) in 2013."
