Terex 860 Excavator
The high popularity of the machine is due to its features such as productivity, versatility, efficiency and implementation of modern production technologies. The Terex 860 Excavator Operating Commission and English Technology are also described in detail. English technology is a four-wheel-drive roller excavator that is most effectively used for construction and street repair, gas, power, and emergency response applications and is purchased by companies that rent it out. This trend has been underway for the past twelve years.
Terex 860 Excavator
Some of the technical characteristics are the same as the model 970 of the same manufacturer. The characteristic feature is the installation on the Terex 970 model of the bucket and the engine with more power.
The reviews of Terex 860 are the most positive, because the equipment proves itself perfectly in solving the complex types of works.
Features and Benefits
Model 860 is the most popular among the company’s products. It is characterized as a modern, productive and versatile machine with well-developed excavator equipment. It is able to work in weather conditions, it is not hindered by high or low temperatures, precipitation, etc. The power plant is characterized by efficiency and long service life. This means that Terex 860 Excavator can be used in any region or climate.

The main advantages of special devices include:
- high quality of parts and assemblies;
- A large number of functions contained in the basic unit;
- Quick-change system for attachments installed;
- Setting the position of the working body in space;
- Installation of illumination of the license plate of the machine;
- The presence of a special signal.
Under the characteristics of the loader is worth noting high transport speed – 41 km / h, the temporary transport costs are reduced directly on public roads. This is due to the presence in the basic set of a special signal – the flashing light. Transportation of machinery from the parking place to the place of work and back is carried out during the working layer. And thanks to the improved fuel system of the Terex 860, operating and transportation costs are significantly reduced.

A synchronized four-speed transmission allows shifting without depressing the clutch pedal. A differential lock-out pedal is also included. Brakes are installed and sealed with oil, which means the wheels can be locked by one or two axles. Maintenance is quick and responsive, with a regularity of 500 mats. The quality of the excavator’s exhausts meets international standards, so the machine is very environmentally friendly.
Modifications
The cost of Terex 860 depends on the modifications offered by the manufacturer. It can be a standard machine, Terex 860 SX or Terex 860 Elite, which is slightly different from the backhoe bucket.

Fuel consumption of the Terex 860 varies with the type of operation, with a minimum fuel consumption of 9.6 liters per hour and a maximum fuel consumption of 15 liters. However, the machine has a large fuel tank capacity of 130L, allowing you to work long hours without refueling.
device
The technology of making the machine body is modern and fast, which increases the quality of the product. After the body is forged from thick steel, it is machined, resulting in a one-piece product with a minimum number of welds, ensuring strength and resilience. This makes the Terex 860 excavator ideal for use in demanding applications. To eliminate the risk of corrosion the body is coated with a special compound that prevents the appearance of rust.
| transmission | Forward travel km/h | Rear travel, km/h |
|---|---|---|
| 1 | 5,4 | 5,4 |
| 2 | 8,6 | 8,6 |
| 2 | 19.9 | 19.9 |
| 2 | 40 |
The Terex 860 features a highly efficient fuel system, providing high fuel economy and excellent performance.
chassis
The Terex 860 offers the advantage of operating in either rear-wheel drive only, or all-wheel drive. This means the operator does not have to stop the machine, but can do it on the fly. The switch is made with a device located to the left of the steering column and has three positions: left – all-wheel drive, middle – rear-wheel drive, braking is done by four wheels, right – rear-wheel drive, braking is done only by the rear wheels. It is also possible to brake one side of the car by installing brake circuits there. This helps reduce the turning radius, which is especially important in tight spaces.
Terex 860 Rear Wheel
The Terex 860 SX Backhoe Loader has a new front axle that improves ground clearance and reduces the turning radius. This makes the machine very maneuverable.
The transmission is a synchronized semi-automatic hydro-mechanical synchronizer. The first and second speeds are intended for work, while the third and fourth are for transport from the construction site to the parking lot or other types of machinery movement. Shifting is done without reducing the speed of the power unit.
Terex 860 Wheels
Hydraulic fluid is used as the brake fluid. This is due to two factors – the toxicity of the original fluid and the versatility of the hydraulic fluid. This gives customers the ability to refill the fluid only in the hydraulic reservoir where it enters the brake system.
The Terex 860 uses a round pedal, positioned to the left of the brake pedal, to lock the differential. This position allows the driver to keep his hands on the steering column and react quickly in case of slippage, and provides convenience by eliminating the need to look for a button on the dashboard.
hydraulic system
Damping valves are fitted as standard on the hydraulic cylinders to protect against unexpected pressure surges. The stable bucket is not subject to dynamic shocks when the Terex 860 excavator moves over rough terrain. The machine’s tires and suspension minimize such shocks.
Terex 860 Hydraulics
The hydraulic transformer has a higher ratio to provide more traction.
operator cab
Terex 860 operator station
The operator station has a 360-degree view in the cab. For operator comfort, door openings have also been modified to provide unobstructed access to the cab. To do the same, an air-cushioned seat and adjustable steering wheel are included.
Terex 860 Excavator Operation
The large interior space of the Terex 860 cab allows the driver to swivel in and out of the seat without leaving the comfort of his feet while working. A powerful cab heater comes as standard, especially important in harsh climates. The rear window, which extends to the cab ceiling, can be opened for good ventilation and better visibility. Part of the window in this case is outside the cab and is a kind of visor.

Joysticks are used to control the automatic synchronized transmission. There is also a foot pedal in the cab for locking the differential.
Terex 860 Steering Wheel
The Terex 860 tractor is equipped with multi-disc brakes. Planetary gears are fitted to the side transmissions.
Easy operation and maintenance
To ensure easy and time-saving machine maintenance and service, the design has changed a few things. These include the installation of a one-piece tilting hood that tilts upward to provide easy access to the engine compartment.

The most important service points are accessible from ground level, which means that certain risks associated with servicing the Terex 860 backhoe loader during or on positioning can be eliminated. Lubrication of the front axle pivot joint is quick and easy because the unit is located next to the cooler. The friction components are lubricated after 10 hours of operation according to the instructions.
Unassembled equipment
The Terex 860 boom is equipped with a special system that makes it easy to mount articulating arms and has safety features. A lifting arm is also defined. The standard Terex 860 bucket is a sliding bucket. You can also order a bucket width from 300 to 900 mm.
Terex 860 Front Loading Bucket
By installing additional hydraulic lines on the boom, the loader can be equipped with a hydraulic hammer, drill, ripped undercarriage and vibrating rail. In addition, there is a 7 in 1 double-crown bucket, a “backhoe” bib with a telescopic boom that can be controlled directly from the cab. The latter gives the machine the ability to dig deeper pits and carry the floor an impressive distance or move it directly to a truck with high sides.

New and used
The price for a Terex 860 SX (new) standard modular is about 3.2 – 4.3 million rubles. A used machine with Terex 860 costs about 1.2 – 2.5 million rubles. Modifications are more expensive, and the major equipment costs are assigned depending on the attachments and additional options.
Companies often purchase special equipment for rent. You can rent a Terex 860 with an hourly fee for about 1,200-1,300 rubles.
Analog
Before you buy a Terex 860 used or new, you should pay attention to the analogue of the machine – Volvo BL61 and JCB 3CX.
