New wheeled loaders from Hitachi
By Becca Wilkins04 December 2008
Hitachi has introduced a 96 kW ZW140 and a 107 kW ZW150 to its ZW wheeled loader range.
The new models join the ZW180, ZW220, ZW250 and ZW310 units, which, according to the company, "have already made a significant impact in key European markets."
"Operators will find the new machines highly efficient due to an innovative hydraulic drive system - the Hydro-Static Transmission (HST). The HST offers greater mobility when fully loaded, smoother control on a gradient and under acceleration and deceleration," said the company.
The HST system's speed selector provides a range of four maximum travel speeds to suit the requirements of each job. When the first range is selected, the maximum speed can be adjusted to four incremental levels, which increase efficiency and simplify operation in confined spaces, the company added.
The ZW140 and ZW150's Optimum Traction Force can also be set to increase efficiency, according to Hitachi.
"The new models offer four work modes that can be selected according to the needs of the job and operator preference. The electronic matching control - originally developed as an industry first - senses the hydraulic pressure and controls traction force which optimises productivity while keeping tyre wear and tear and fuel consumption to a minimum," the company said.
All controls, switches and pedals in the ZW140 and ZW150 cabs are ergonomically designed and positioned for ease of use and there is an optional multi-function joystick or double lever.
According to the company, the cab is spacious and comparable to that of a larger Hitachi wheeled loader. Its fully adjustable air suspension seat and tilted steering column provide comfortable and variable working conditions.
Enlarged windows and generous rear view mirrors give excellent all-round visibility, allowing the operator to directly see the movements of the bucket for safer operation and increased loading efficiency.
The ZW140 and ZW150 also benefit from durable components like HN bushings, axles, transmission and brakes. The new HN bushings increase lubrication intervals from 100 to 500 hours, helping to extend service intervals and reduce downtime.
Hitachi said the throttle limit helps to reduce fuel consumption by up to -12 % when the maximum speed is lowered by -10%. The company added, the cooling system features a hydraulically operated cooling fan which adjusts according to the fluid temperature, ultimately reducing fuel consumption.
