OREANDA-NEWS. June 06, 2011. New construction and road-building equipment is exhibited at GAZ Group’s stand at the 12th International Specialized Show ‘Construction Equipment and Technologies 2011’ taking place in Moscow. GAZ Group presents three upgraded excavator models produced by ‘Tver Excavator Plant’: EK-14-90 pneumatic wheel excavator, ЕТ-18-90 crawler excavator, TEP-18 multi-purpose multi-functional excavator-leveler, reported the press-centre of GAZ Group.

EK-14-90 pneumatic wheel excavator and ЕТ-18-90 crawler excavator belong to a new lineup of upgraded machines in the third size group designed for a wide range of construction and earthmoving works. 14t and 18t excavators are highly unified. They have more powerful engines with enhanced eco-friendliness; hydraulic systems using high quality Bosch-Rexroth components; upgraded hood systems, fuel and hydraulic tanks, cabin and the operator’s seat. Through the excavator upgrade, such consumer characteristics as ease of operation and working capacity have been further improved, the warranty period has been extended, cost of ownership has been reduced, and maintenance has been optimized.

In addition to regular excavator functions, TEP-18 excavator-leveler has enhanced mobility and extensive technological capabilities, such as operation in hard-to-get places and finishing operations on slopes and slants. The excavator has an all-wheel drive platform and is equipped with a telescopic boom with a working attachment that can revolve around longitudinal axis. The excavator can be used for rescue and recovery operations, maintenance of various utilities, including pipeline systems. The components and systems of the leveler’s excavator unit are very similar to a regular excavator, and do not require special preparation for maintenance and repair.

Customers of the new excavators have more opportunities to adapt these machines to the existing conditions of operation. In addition to changeable working attachments, the list of optional equipment now includes air conditioner, audio system, fuel-efficient control system, and equipment for manual hydraulic tools connection.

The exposition also features upgraded models of medium-series front loaders, heavy-duty motor grader produced by ‘Chelyabinsk Construction and Road Machines’. A new model of V130 front loader has been designed specifically for utility and municipal services. The main advantage of this machine is payload increased to 3 tons with relatively small dimensions and weight of the machine. The loader is powered by Euro-2 engine, which makes it possible to use this machine in residential areas. New models will be equipped with quick-detachable working attachments.

V150 front loader is presented with a new design of the front and rear semi-frames. Changed design of the bucket has made it possible to increase payload up to 5 tons keeping the same unloading height. All upgraded models can be equipped with a quick-detachable hydraulic clamp, which makes it possible to change the equipment from inside the cabin. It greatly extends the range of front loaders’ application. All components of the new model are highly unified with V140 series front loader.

DZ-98M motor grader is the only heavy-duty motor grader in its class that operates in severe conditions of northern latitudes. Due to changed design of the frame, the upgraded model of DZ-98M motor grader can be equipped with a rear ripper, which considerably extends the scope of this machine’s application. The motor grader has a new cabin. Its characteristic features include enhanced comfort of the operator’s seat, improved visibility and reduction of noise.

A brand new model of GAZ-3344 double-unit crawler snow and swap-going vehicle is exhibited for the first time. The characteristic features of the machine include enhanced cross-country capacity and ability to negotiate more complicated obstacles in comparison with single-unit snow and swap-going vehicles. It is achieved by transfer of the engine torque to the tracks of both units, low specific pressure on the soil, units folding without change in traction and speed, and system of forced folding in the vertical plane. The first unit of the snow and swap-going vehicle is a power module which has a five-seat cabin, and transmission and motor compartment. The second unit can be used as a base chassis for various complementary equipment: drilling rig, telescopic tower, forest patrol unit, medical module, technical support unit etc. The machine can be used in extremely severe road and climatic conditions, to transport people and cargoes off public roads. The snow and swamp-going vehicle is equipped with asphalt-going track assembly with metal and rubber mounting and detachable rubber shoes.

GAZ Group’s stand also displays renewed models of GS-18.07 motor grader and ASF-G-3-08 asphalt paver produced under ‘Bryansk Arsenal’ brand. ASF-G-3-08 crawler asphalt paver is designed for construction and repair of motor roads, squares and aerodromes. The machine’s power plant has D260.1 engine, which is widely used in the Russian construction and road-building equipment market. ASF-G-3-08 has enhanced reliability and durability due to application of some imported components by Bosch-Rexroth and Sauer Danfoss. The machine has high performance due to wider scraper conveyors. The operator’s seat conforms to the modern ergonomics requirements, which makes the operator’s work more comfortable.

GS-18.07 motor grader is very powerful (200 hp), has enhanced reliability structure, enhanced traction and towing characteristics, more comfortable working conditions for the operator, and exceptional mobility of the grader blade, which makes it possible to use big cutting angles for trenches and profile slants beyond the machine track. GS-18.07 motor grader cabin has enhanced visibility, is equipped with induced draft fan, sliding door, new adjustable steering column and adjustable operator’s seat ‘Pilot’.
