Zil mmz 4505: technical characteristics of the dump truck

The designation ZIL-4505 is assigned to a construction and industrial dump truck equipped with a platform with beveled lower edges of the sides. Serial production was mastered by the machine-building plant in Mytishchi in 1987. The chassis used were trucks with a wheelbase of 3800 mm, built at the ZIL and UAMZ (Amur) plants.

Device and technical characteristics

The model 495710 chassis, equipped with a 2-section brake valve, was used as the basis for the dump truck. On the rear cross member of the frame there was a towing device equipped with a 2-way rubber damper. Nearby were installed connectors for connecting the brakes and electrical circuits of the trailer. The design of the machine made it possible to connect the hydraulic system of the trailer and carry out simultaneous or separate unloading of the bodies.

The dump trucks used a 150 hp carburetor engine. With. at 3200 rpm. The engine was built according to a V-shape, the camber angle of the cylinder blocks was 90°. A low compression ratio made it possible to use grade A 76 gasoline as fuel. The fuel supply was stored in a 170-liter tank installed on a special cradle, which is mounted on the side of the spar.

The machines used a 5-speed gearbox equipped with a power take-off gearbox to drive a hydraulic pump. The pumping station was equipped with a safety valve that prevented pressure from rising above 14 MPa. The liquid supply was stored in a separate tank with a capacity of 19-21 liters. The dumping equipment was mounted on a steel subframe mounted on the main chassis frame through damping pads.

Technical characteristics of the dump truck:

• load capacity - 6000 kg;
• curb weight (with fuel supply, but without driver) - 4905 kg;
• permissible trailer weight - 8000 kg;
• wheelbase - 3800 mm;
• length - 6185 mm;
• width (excluding the extension of the side mirrors) - 2500 mm;
• height (to the edge of the protective device) - 2525 mm;
• body floor height from the ground - 1330 mm;
• driving speed (with a full load on a flat section of the highway) - 90 km/h.

The ZIL-MMZ-4505 uses a platform with the following parameters:

• number of unloading directions - 1;
• maximum platform elevation angle - 50°;
• the time required to unload the body is no more than 15 seconds;
• body capacity - 3.8 m³;
• length - 2990 mm;
• width - 2270 mm;
• side height - 580 mm.

Modification 450501, intended for work in the Far North, was assembled in small batches. The cabin walls were covered with insulation and double glazing was used. The rear window was covered with a metal sheet. An additional tank designed to hold 65 liters of gasoline was mounted between the frame side members. An autonomous heater was installed in the cooling system. Some of the machines had a winch driven by cardan shafts from the power take-off gearbox.

The designation MMZ-45054 was given to an experimental dump truck mounted on a ZIL-138AB gas-cylinder chassis. The cars were planned to use a 120 hp engine. pp., the gas supply was stored in cylindrical cylinders installed under the bottom of the platform. In 1982, there was another experimental MMZ-45054, which featured an engine with an increased compression ratio that developed 135 hp. With. Gas or leaded gasoline AI-93 could be used as fuel.

The plant in Mytishchi was unable to quickly master the production of superstructures, so dump trucks entered the series in 1987. The equipment had a load capacity of 5100-5300 kg (depending on the type of cylinders). The compressed gas was in 8 containers with a capacity of 50 liters each. Some of the cylinders were attached to the frame, and 3 were attached to the subframe. The available supply of gas fuel was enough for 200 km, so the dump trucks retained a standard gasoline tank. The plant assembled cars for the domestic market and also exported them to countries with temperate and tropical climates.

Features of the cargo platform

The cargo platform has overall dimensions of 2990 x 270 x 800 mm. Due to the presence of straight sides with beveled lower corners, sticking of cargo during unloading of the body is excluded. A straight-sided body has a number of advantages compared to other forms - it takes up a minimum of space, while accommodating the maximum usable volume. The mass of the cargo is distributed evenly across the platform, and is also evenly distributed throughout the area during unloading. Since the body is light, the vehicle’s own weight is also small. The ZIL 45085 dump truck model has a total weight of 11.2 tons.

Unloading is carried out through an opening tailgate, which is a specific feature of construction dump trucks. Easily removable rubber seals, which are attached to the sides and bottom of the body, allow minimizing cargo losses during transportation. The carrying capacity of the ZIL 45085 is 5.5 tons, and the dump platform can hold up to 3.8 cubic meters. materials.

It is possible to install additional extension sides, allowing you to increase the volume of the cargo platform, which is important in a number of cases, for example, when transporting not so heavy, but very voluminous ones. The body is tipped by a hydraulic device. The power take-off and pump are electro-pneumatically driven and are activated remotely from the cab. The hydraulic distributor, which has manual control, is also switched on. There is a protective cabin canopy installed on the middle side.

Made in Mytishchi. ZIL dump trucks produced by MMZ

The Likhachev plant supplied work not only to many related factories that supplied spare parts and components, cars on the ZIL chassis were produced in Novouralsk (later produced as AMUR trucks), in Chita they mainly made cars in the northern version, in Mytishchi they specialized in dump trucks.

The Mytishchi Machine-Building Plant was created in 1987, for a long time it specialized in military equipment, and in the post-war period it was repurposed for the production of trucks.

In 1947, based on the ZIS-5V truck, which had a payload capacity of 3 tons and a 73 hp engine, the production of the ZIS-MMZ-05 dump truck began in Mytishchi.

Design features. Closest relatives – ZIL-4514, ZIL-4516

The basis of the ZIL 4520 dump truck is the base chassis ZIL-133D42 produced by the capital's Likhachev Automobile Plant. This three-axle chassis was originally intended specifically for the ZIL-4514 construction dump truck. This model was put into production in 1993. Cargo dump truck ZIL-4514 – Neftekamsk dump truck plant, absolutely similar to the one installed on three-axle KamAZ-55111 dump trucks. ZIL-4514 dump trucks were produced from 1993 to 1997, and cargo platforms were installed on the ZIL-133D42 chassis not only by the Neftekamsk plant, but also by the Orsk tractor trailer plant (although the latter, of course, produced much fewer such vehicles).

Recognizable KamAZ body on ZIL 4514

Another manufacturer of dump truck platforms (metal body and hydraulic tipping device for unloading the body) - Mytishchi Machine-Building Plant - also began installing its own version of a dump truck on the ZIL-133D42 chassis, in the same 1993. The result is a new version of the universal industrial construction dump truck - ZIL-MMZ-4520. The Mytishchi body with a rounded “trough-shaped” lower part is significantly different from the NefAZ one - bucket-shaped, angular.

Mytishchi version: ZIL 4520.

The loading platform of the ZIL-MMZ-4520 dump truck was specially made with these bevels on the side sides to prevent sticking of the transported wet bulk cargo. Control of the hydraulic tipping device: activation of the power take-off and pump is remote, electro-pneumatic from the driver’s cabin; The hydraulic distributor is activated manually from the driver's cab.

An agricultural dump truck was also developed on the ZIL-133D42 base chassis: ZIL-MMZ-4516. This version of the ZIL three-axle dump truck received a loading platform with the ability to unload on the western side. It was designed for transportation and quick unloading of grain and other agricultural cargo along public roads, including unpaved roads and in field conditions. The configuration of this vehicle included the installation of an awning on the body to ensure the safety of the cargo.

Cabin

The ZIL 4505 has the same all-metal cabin as the 130, which allows you to take up to three people on board.

The driver has a separate seat with several adjustments. A double sofa was used for passengers. For operation in conditions of low negative temperatures, an efficient heating system is installed inside.

The interior of this car remained the same as that of the ZIL-130. There are no plastic elements here, all the trim is metal. The dashboard contains only the most necessary indicators. The main advantages of this cabin are the high seating position and ergonomic location of all controls. The comfort level is quite good for its time.

The cabin has average visibility. Due to the high, massive hood and voluminous fenders, there are many blind spots, but over time, drivers got used to it.
