约翰迪尔混合动力轮式装载机工作时间达到一百万小时

2021-01-13

约翰迪尔944K混合动力轮式装载机的耐用性较高,有客户表示其944K装载机已经在工地工作了100万小时。

“我们在开发机器时,始终将客户的需求(例如耐用性、生产率、盈利能力和较低的运营成本等)放在首位。基于944K装载机实现工作100万小时,我们确定电力驱动的机器为我们的客户提供了久经考验的耐用性和性能优势。” 约翰迪尔解决方案营销经理Grant Van Tine说,“我们一直在寻找新的方法来改善客户所需的设备,并且可以使用我们经过实地测试的设计来开发和完善更多的解决方案。

944K混合动力车型于2015年推出,为客户提供了可靠、经济高效的解决方案。 944K混合动力车具有536马力的发动机,在保持动臂和铲斗速度的同时,提供了令人印象深刻的扭矩和响应能力。Cornejo&Sons(Summit Materials)的经理Adam Ware说:“ 944K满足了我们的生产要求,而且成本更低。另一台机器每小时消耗约24加仑燃料,而944K在执行相同工作时每小时消耗约9加仑。”

除了省油功能外,944K混合动力机型还集成了其他功能以提供长期性能,尤其是在采石场或大型装卸应用中,包括无刷交流发电机和电动机、水冷制动电阻器和固态电力电子设备等。与传统的传动系统相比,944K的电驱动系统通过取消变矩器和传动装置的改造,大大降低了客户的运营成本。

John Deere hybrid wheel loader reaches 1 million field hours

A testament to the durability of John Deere machines, the 944K hybrid wheel loader has logged 1 million operating hours in the field.  

"Whenever we develop a machine, customer needs, such as durability, productivity, profitability and low operating costs, are always at the forefront of our designs. By reaching the 1 million-hour mark on our 944K loaders, we are affirming that electrically driven machines offer proven durability and performance advantages for our customers," said Grant Van Tine, solutions marketing manager for John Deere. "We're always looking for new ways to improve upon the equipment our customers need and can use our field-proven design to develop and perfect even more solutions in the future.

First launching in 2015, the 944K Hybrid model provides customers with a reliable, cost-effective solution. The 944K hybrid features a 536-horsepower engine, which delivers impressive torque and responsiveness while maintaining boom and bucket speed. At Cornejo & Sons (Summit Materials), the 944K replaced a size-class larger competitive wheel loader. "The 944K meets our production requirements as well as our previous piece of equipment, and at a lower cost," said Adam Ware, site manager for Cornejo & Sons (Summit Materials), which owns a 944K hybrid wheel loader. "The other machine burned about 24 gallons of fuel an hour, where the 944K burns around 9 gallons per hour while doing the same work."

In addition to its fuel-saving capabilities, the 944K hybrid also incorporates other features to deliver long-term performance, especially in quarry or large loadout appliCATions. Most notable are the brushless AC generators and motors, water-cooled brake resistors and solid-state power electronics. The 944K's electric drive system significantly reduces operating costs for customers compared to conventional drivetrains by eliminating torque converter and transmission rebuilds at mid-life.

Other key features include standard traction control, which automatically limits torque to any wheel when slippage occurs, increasing machine traction in poor underfoot conditions, and enhanced rimpull control to virtually eliminate tire spin and slicing. Coast control reduces service-brake wear and includes functions, like dynamic braking in a hydrostatic transmission, slowing the loader without touching a pedal and helping to reduce service-break component wear.
