The design is reliably protected from the outside, which prevents dust, moisture and air from entering, which has a beneficial effect on the service life of various parts of the JCB JS160W rotary mechanism. The protection provided by the British allows you to increase the service life of the lubricant for gears, as well as parts of the cab rotation mechanism.

The full-rotary platform is driven by an axial piston hydraulic motor equipped with a planetary gearbox.

Mini models of wheeled excavators

Almost all manufacturers of special construction equipment produce compact and maneuverable mini-excavators, which are not very productive, but are indispensable in tight operating conditions. Today, this category is represented by small-sized models weighing no more than 12 tons. On average, the weight of such a machine is 8 tons.

In terms of functionality, such models also have something to boast about. The equipment is equipped with rammers, hydraulic hammers, mechanical grips, tongs, leveling boards and clamshell buckets. However, mini excavators still provide fairly weak digging force compared to their full-size counterparts.

Price

It cannot be said that the model belongs to the segment of budget construction equipment. So, the new version will cost in the range from 7 to 9 million rubles, depending on the modification. As for construction equipment with accumulated working life, its cost depends on several categories:

• year of issue;
• operating hours;
• technical condition;
• type of modification;
• appearance.

So, a car produced in 2008-2009 will cost approximately 2 to 4 million rubles. Older equipment in good condition will cost 1.5 million.

However, it is worth considering that the JCB JS160W excavator can be rented for one or several work shifts. This is advisable if the equipment is used infrequently: rent for one shift is 12 thousand rubles.

This is a British excavator of increased strength and reliability. Thanks to the equipment of construction equipment with units produced in Japan, the USA and Great Britain, a comfortable and functional cabin, the high strength of the machine and its versatility, the excavator is in great demand. Even used cars sell quite well. This is explained not only by the high reliability and functionality of the machine, but also by the high price of excavators just off the conveyor belt. The JS160W is a reliable, comfortable and functional excavator that makes even the toughest jobs easier.

Classification of wheeled excavators

A wheeled excavator (from the Latin excavo - hammer) is a special machine for excavating, lifting and moving soil, mounted on pneumatic wheels. Excavators, due to their wheeled chassis, are highly mobile and can change locations in the shortest possible time and without special means of transportation. Machines of this type are used in construction, housing and communal services, energy, for repair work, planning and other excavation work.

History of wheeled excavators

Historically, the first were excavators on rails; in the second decade of the 20th century, tracked vehicles appeared, and the first wheeled excavator was created only in 1948. The appearance of excavators on a wheeled chassis was facilitated by a reduction in the weight of working equipment, an increase in the carrying capacity of vehicles and the development of a hydraulic drive. The first serial wheeled excavator was the Italian Yumbo S25, mounted on a car chassis. In the 1950s, machines began to be produced on a specially designed chassis and mounted excavators for mounting on wheeled tractors. All these types of technology exist today, solving their problems in various fields.

General structure of a wheeled excavator

There are two main elements in the design of the machine:

• Wheeled chassis with power unit, outriggers and other equipment;
• Excavator equipment with hydraulic drive.

Depending on its type, the design of a wheeled excavator may contain additional equipment: a blade, a bucket loader, and others. Modern machines are equipped with a cabin with an operator’s seat, various automated systems, light and sound alarm systems, etc.

Classification of wheeled excavators

Wheeled excavators are classified by chassis type, type of working equipment and characteristics.

Wheeled excavators can be installed on:

• Chassis of serial trucks;
• Specially designed pneumatic tire chassis of automobile type or with a short wheelbase;
• Wheeled tractor, loader, tractor, etc.

The machines can be equipped with the following types of working equipment:

• Continuous action - rotor or chain for longitudinal or transverse digging (trenchers, drainage machines);
• Cyclic action – single-bucket equipment on a boom with a hydraulic drive.

Cyclic excavators are divided into two groups:

• Universal – with an articulated-lever boom;
• Planners – with a telescopic boom.

In all cases, single-bucket excavators can be equipped with a front or backhoe, and levelers can be equipped with a rotating bucket. Also, the equipment of cyclic machines can be full-rotary or part-rotary, this largely depends on the type of chassis.

Characteristics of wheeled excavators

The main characteristics of wheeled excavators include weight, engine power, bucket volume, digging depth, bucket lift height, travel speed and others. Based on weight, wheeled vehicles are divided into several size groups:

• 1 group – up to 6.3 tons;
• Group 2 – from 6.3 to 10 tons;
• Group 3 – from 10 to 18 tons;
• Group 4 – from 18 to 32 tons.

The bucket capacity of wheeled excavators ranges from 0.15 to 1.7 cubic meters. m, height and digging depth - from 2 to 9 m (planners - up to 10 m or more), moving speed depends on the chassis and can reach 60 - 80 km/h.

In Russia, the characteristics and design features of excavators are regulated by GOST 30067-93, GOST 21796-90 and other documents.

Leading manufacturers of wheeled excavators

Wheeled excavators are a narrow niche in which a small number of companies operate. In Russia, such machines are produced at UVZ (EO-33211 series), (EK-8 - EK-20 series) and Eksmash (several series, including E130W and E160W from foreign components). The leading foreign manufacturers are Caterpillar, Komatsu, Liebherr and New Holland; wheeled vehicles are also produced by Case, Hitachi, JCB, Terex, Volvo, Hyundai and some other factories.

Interesting facts about wheeled excavators

One of the key advantages of wheeled excavators is the ability to move independently on public roads. Therefore, such cars have dimensions and weight that fit into standard road dimensions. Even the largest excavators and backhoe loaders weigh no more than 21 tons and are equipped with an engine no more powerful than 210 hp. With.
