KOMATSU 980E-4 Camiones de transporte
Características del producto
Retardador dinámico eléctrico
The 4476 kW 6,000 HP retarding system provides state of the art braking capacity for navigating today’s mining applications which contain steep continuous descents and sharp switchbacks. Continuous retarding capacity enhances the productivity of the vehicle operator, while eliminating the need for excessive mechanical braking effort.
Cuerpo específico de aplicación diseñado por Komatsu
Utilizing the required Cuerpo Worksheet (BW) process, Komatsu ensures that each body is designed to meet the requirements for each specific application while carrying its rated payload. Komatsu works with each customer to understand the material properties at a mine site and to identify the appropriate liner package.
KOMTRAX Plus®
As part of a complete service and support program, Komatsu equips every mining and quarry sized machine with Komtrax Plus®. By using a satellite-based communication system, Komtrax Plus® offers a new vision of monitoring your valuable assets. By providing insight to critical operating metrics the user can manage increased availability, lower ownership and operating costs and maximize fuel efficiency.
Sistema hidráulico simple y confiable
The hydraulic system is a proven and reliable design with fewer parts than other OEMs. The system utilizes a single tank, providing one common source of fluid for steering, braking, and hoisting. In-line, replaceable filtration elements provide protection from hydraulic system contamination, making the system easier to service.
Diseño de marco mejorado estructuralmente
By using advanced computer-aided design, finite element analysis, and full-scale static and dynamic testing, the frame has been designed to carry 363 metric tons 400 toneladas cortas and provides the high structural reliability Komatsu is known for.
Cuerpo
All-welded steel flat floor body with horizontal bolsters and full canopy. Rubber mounts on frame, eyebrow and body up sling are standard. Extended canopy and pivot exhaust heating are optional.
Sistema de frenado
Continuously rated high-density blown grids w/retard capacity at low speeds and retard in reverse propulsion.
Cabina
Sistema de enfriamiento
Replaceable core radiator assembly, split-flow, with deaeratortype top tank
