Offering a capacity of 91-tonnes and mechanical drive, the HD785-7 has the highest brake retardation in its class. Standing 5.05 m tall\u2014as tall as the average telephone pole\u2014this is a machine that demands respect from the get-go. <\/span><\/p>\n<p><span style=\"font-weight: 400;\"><a href=\"https:\/\/www.machines4u.com.au\/brand\/komatsu\/\" target=\"_blank\" rel=\"noopener\">Komatsu<\/a> say they\u2019ve made some improvements in this mining dump truck, \u201c[The] HD785-7&#8230; features higher productivity, improved fuel economy and compliance with regulations.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">When updating the older model to the HD785-7 features, there were 6 main areas of focus:<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">1. Productivity &amp; Economy<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Under the \u2018bonnet\u2019 of this massive machine you will find a high-performance engine. This engine delivers faster travel speeds and high hp per tonne. <\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">High torque at low speed<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Impressive acceleration<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Low fuel consumption<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">When discussing lower fuel consumption, Komatsu technical writers reported, \u201c&#8230;Depending on the travel conditions and required work rate, [Variable Horse Power Control (VHPC)] automatically changes the engine power to high output when earth is being loaded. Then to low output when detecting the loading of earth or idling by the vehicle itself. Significantly reducing fuel consumption.\u201d<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">2. Environmentally Conscious<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Komatsu upgraded the engine and ensured it is EPA Tier 2 certified. Engineers also made other changes to lessen the truck\u2019s impact on the environment:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Lead-free radiator<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Low operation noise<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Low fuel consumption<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-weight: 400;\">3. Operator Comfort &amp; Productivity<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Large-scale mining jobs require long hours in the cab. Knowing this, Komatsu have ensured the HD785-7 mining dump truck is easy to use while being easy on the operator. This includes:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">A spacious cab with excellent visibility<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Ergonomic design for greater comfort and productivity<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Easy-to-read instrument panel<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">5-way adjustable operator seat and tilt-telescopic steering column<\/span><\/li>\n<\/ul>\n<blockquote><p><span style=\"font-weight: 400;\">\u201c[There are] wide glass areas on the front, side and back. Plus plenty of space in the richly upholstered interior, all provides a quiet, comfortable environment to see and control every aspect of operation. Front under-view mirrors also contribute to improved visibility.\u201d<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">\u2014Komatsu<\/span><\/p><\/blockquote>\n<p><span style=\"font-size: 22px; color: #222222;\">4. Operator Safety<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Working on a mine site, safety is paramount. Along with the standard safety features (like ROPS\/FOPS cab, spiked, slip-resistant plate and LED rear combination lamp) Komatsu offer:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">A new circular under-mirror<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Parking brakes on 4 wheels<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Supplementary steering and secondary brake<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Pedal-operated secondary brake<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-weight: 400;\">5. Reliability<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">As they say, \u201ctime is money\u201d and downtime on a mine site can mean millions. To minimise breakdown risk, Komatsu focus on reliability by providing:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Komatsu components made under strict quality-control guidelines<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">A high-rigidity frame <\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Flat face-to-face o-ring seals to securely seal all hydraulic hoses<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Sealed DT connectors on main electric harnesses and controller connectors<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-weight: 400;\">6. Easy Maintenance<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">To keep the HD785-7 in good condition, while minimising operating costs, Komatsu have extended oil change intervals. Engine oil is now 500 hours, and hydraulic oil is 4000 hours. On top of this, they have introduced:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">An advanced monitoring system which displays abnormality codes to reduce diagnostic times<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Wet multiple-disc brakes and full hydraulic-controlled braking systems<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Easy access to filters and greasing points for servicing<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Electric circuit breaker for quick restoration in a malfunction<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">KOMTRAX Plus controller for constant monitoring the health of major components<\/span><\/li>\n<\/ul>\n<h2><span style=\"font-weight: 400;\">Komatsu Dump Truck HD785-7 Price<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Komatsu HD785-7 haul trucks were listed between $1,150,000 and $1,300,000, averaging at $1,225,000.* <\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Mining Dump Truck Specs Quick View<\/span><\/h2>\n<p><b>Engine:<\/b><span style=\"font-weight: 400;\"> Komatsu SAA12V140E-3<\/span><\/p>\n<p><b>Cylinders:<\/b><span style=\"font-weight: 400;\"> 12<\/span><\/p>\n<p><b>Horsepower (gross): <\/b><span style=\"font-weight: 400;\">1,200<\/span><\/p>\n<p><b>Horsepower (net): <\/b><span style=\"font-weight: 400;\">1,178<\/span><\/p>\n<p><b>Maximum Torque:<\/b><span style=\"font-weight: 400;\"> 5080N m 518kg m <\/span><\/p>\n<p><b>Rated Gross Vehicle Weight (GVW):<\/b><span style=\"font-weight: 400;\"> 163,780 kg (includes optional equipments, operator (80kg) and payload)<\/span><\/p>\n<p><b>Rated Payload Capacity:<\/b><span style=\"font-weight: 400;\"> 91.7 metric tons<\/span><\/p>\n<p><b>Dumping Angle: <\/b><span style=\"font-weight: 400;\">48 degrees<\/span><\/p>\n<p><b>Height (fully raised): <\/b><span style=\"font-weight: 400;\">10,080 mm<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Have you seen or operated one of these monster trucks?
