Doosan DL500 wheel loader combines powerful performance with operator comfort and ease of maintenance
The 335-horsepower Doosan DL500 wheel loader combines powerful performance with a quiet, comfortable cabin and easily accessible maintenance points. With available buckets ranging from 5.9 to 6.8 cubic yards, the DL500 is designed for larger material handling applications, such as quarries, mines, demolition and industrial operations.
A robust Z-bar lifting system provides a bucket breakout force of 61,373 pounds. Depending on the application, the operator can choose between two working modes (Standard or Economy) in order to maximize production or minimize fuel consumption. Plus, standard limited slip differentials on both the front and rear axles allow the DL500 to tackle the toughest terrain, delivering powerful pushing force and providing superior penetration into the hardest materials.
Like all Doosan wheel loaders, the DL500 features a full powershift transmission with Manual and Automatic modes for smooth, comfortable shifting and outstanding traction in every working condition. Four forward speed ranges provide maximum speeds of 3.9, 7.1, 11.2, and 21.7 mph; while three reverse speed ranges offer maximum speeds of 3.9, 7.1 and 15.2 mph.
The DL500 has a static tipping load of 50,387 pounds at maximum reach with a straight frame and 43,810 pounds at the maximum steering angle of 40 degrees. Dump height with the 6.8-cubic-yard bucket is 10 feet 9 inches and dump reach is 4 feet 3 inches. Height at the bucket pivot point is 15 feet 1 inch.
To reduce fuel consumption and lower noise levels, the DL500 features a hydraulically driven, variable speed cooling fan with an electronic thermostat that constantly monitors engine coolant and transmission oil temperatures. The fan direction can be reversed from the operator’s cabin to quickly clean out the radiator in dusty environments, and the fan itself swings out to easily clean the entire cooler group.
Hydraulically controlled, multi-plate wet disc brakes and dual brake circuits provide excellent braking power. The brake system is also self-adjusting for maximum life. A spring-applied/hydraulically released (SAHR) parking brake is mounted on the transmission shaft to prevent the loader from rolling after engine shutdown. An optional electric-powered emergency steering system backs up the hydraulic power steering system in case of a malfunction, and a starter interlock system prevents starting the engine when the transmission is not in neutral.
Cabins on the DL500 are designed quiet and spacious with outstanding all-around visibility, and a powerful heating and air conditioning system help improve operator productivity and lessen fatigue. Other amenities include a tilting and telescoping steering wheel, heated outside mirrors and an ergonomically designed central monitoring panel that allows the operator to see all status and warning lights at a single glance.
Available options include an air suspension seat and a load isolation system for smoother travel with a loaded bucket. Also available is a single lever control for travel functions and front-mounted attachments.
Additionally, all routine maintenance on the DL500 can be performed from ground level. Centralized hydraulic check ports and easily accessible drain valves for engine oil and coolant simplify routine maintenance. Remote greasing lubrication points allow the lift arm pins to be lubed from the outside of the machine, and the transmission oil filler pipe is located near the articulation joint for easy access and sight gauges for hydraulic oil and coolant levels allow easy daily checks while reducing the risk of contaminants entering the systems.
