777 (07) Bare Chassis
777 bare chassis - 2022 (Global)
Overview
Caterpillar offers partial machines and systems, working with Cat dealers and Original Equipment Manufacturers (OEMs) to provide specialty machines for specific applications. Bare chassis trucks (WTR models) can be ordered with or without hoist cylinders and most product options are identical to the dump truck models. Typically, these models come equipped with the higher Tractor ROPS certification ratings needed for specialty machines including water trucks, tow trucks, and fuel / lube trucks. These partial machine configurations are used in construction, demolition, waste, material handling, quarry, and mining applications.
The Cat Water Delivery System (WDS) is available as an optional attachment with the 777 WTR, 785D WTR, and 789D WTR Off-Highway Truck Bare Chassis and includes factory installed controls in the cab, a hydraulic pump and motor, a water pump and stainless steel spray heads. Whether your goal is dust control or haul road maintenance, the Cat WDS is designed to put water to the ground in a controlled, intelligent way. The simple to operate automated system allows you to concentrate on more important safety issues like traffic, personnel and road conditions. You'll also find that the Cat WDS not only improves safety, but also reduces truck maintenance costs, conserves water and provides significant fuel savings to help your bottom line.

Detect
On the surface, operators in the cabs of large mining equipment often cannot see if another machine or vehicle is too close for safe operation. Detect helps alleviate this potential safety hazard and can also be configured to provide valuable information about site conditions and other assets working in the area. Underground, continuous equipment movement on a longwall face can pose risks to those in the working area.
Equipment Management
Cat® Equipment Management gives you access to the data you need to keep your equipment on the job site and earning money. You can track equipment location and hours, monitor machine use and health, then take informed action that will keep your operation running smoothly, efficiently and profitably.
Payload
Cat® Payload technologies provide on-the-go load weighing to assist operators with hitting precise load targets every time, helping to reduce load times, optimize loading efficiency and increase jobsite productivity. Operators can track daily productivity from the cab, with quick access to information such as truck target weights, loads and cycle counts, material movement and daily totals. When combined with Cat Link technologies, detailed data can be accessed remotely to manage overall operations and keep production targets on track.
Productivity
VisionLink® Productivity is a cloud-based application that is scalable to any size operation. Detailed Cat Production Measurement data, machine data and jobsite data are transmitted from the onboard Cat Product Link™ device directly to the web platform, for you to access wherever you are, via your mobile, tablet or desktop device.
