Hitachi has announced the launch of ZW180-7 and ZW180PL-7 wheel loaders for construction projects. The 3.5-cu.-yd. wheel loaders feature 33,047-lbs. (1,490 kg) of operating weight. The ZW180-7 offers either standard or high-lift front arms for bucket applications.
The ZW180PL-7 features a parallel link arm configuration. It can be used in fork and tool carrier applications by keeping attachments parallel with the ground as the loader arms move up or down. This allows control while loading or unloading items. The parallel link arm configuration also allows visibility when using forks and other attachments.
“With the three front linkage options, these wheel loaders offer the versatility to handle any application, whether the loader is used to move pallets around the yard, load materials into trucks or manage stockpiles,” said Matt Koester, wheel loader product manager, Hitachi Construction Machinery Americas Inc.
Both models are powered by a 173-hp (129 kW) Cummins engine.
Control and Operation
Approach speed control and an auto power up function are available on the machine. With approach speed control, the travel speed can be adjusted with fewer pedal operations during loading. Travel speed is controlled through the five-speed transmission during short loading operations. Limited-slip differentials also support traction in demanding applications. The auto power up function is for hill climbing performance. It identifies slopes and adds power to prevent the engine speed from dropping when travelling uphill.
New for the ZW180-7, a payload weighing system uploads information reporting data to the ConSite telematic system. Operators can check the weight of the load in the bucket from the inside cab monitor and log the material loaded. It offers four modes — tip-off to truck, tip-off to pile, auto-add and manual-add. These modes allow the payload weighing system to manage loads according to their application. In addition, the unit is equipped with a warning function that reacts when the bucket is overloaded.
Cab and Visibility
The ZW180-7 and ZW180PL-7 are equipped with large and quiet cabs. The machines have seat-mounted armrest with ergonomic electric hydraulic controls, ergonomically located switches and adjustable seat and mirrors. An 8-in. (20.3 cm) anti-glare LCD monitor with Bluetooth radio allows hands-free phone capacity.
The position and design of the cab pillars, the layout of the monitor and switch panel have been improved for a wide field of view from the cab.
Hitachi takes visibility a step further with its Aerial Angle peripheral vision camera system. It provides a wide 270-degree bird’s-eye view of the machine’s immediate environment. Aerial Angle includes three cameras mounted on the rear of the machine. Operators can see both the left and right sides of the machine on the monitor inside the cab.
An optional rear obstacle detection system with automatic speed reduction is available on the Hitachi ZW-7 wheel loader product line. It offers rear object detection alerts.
An inner element of the engine air filter protects the engine from dust ingress while cleaning the outer element. The air conditioner is protected with a sealed internal filter that prevents intrusion of dust into the air conditioner unit.
Airborne debris can become an issue in many wheel loader operations, often leading to decreased cooling system performance. Hitachi addressed this with an intelligent automatic reversing hydraulically driven fan and wide-fin radiators which prevent clogging. Daily maintenance has been simplified with accessible filters and components.
Using telematic tools to monitor machine health also supports uptime. ConSite Air is a new optional add-on that allows the wheel loader to be diagnosed remotely, as well as remote updates of the software. No matter where a machine is located, the servicing dealer can diagnose issues that may arise, supporting uptime. A ConSite response team is on standby to resolve issues as they emerge.
