All about sawmills "Altai"

Sawmill - woodworking equipment used in enterprises for longitudinal sawing of logs and beams of different tree species. The sawmill plant "Altaylestekhmash" is considered one of the most famous enterprises specializing in the production of such equipment. It produces several types of machine tools, differing in design, operating principle and technical characteristics.

Altai sawing equipment production plant began its work in 1996. Initially, he specialized in the production of gasoline sawmills and electric belt-type machines. Today the enterprise is one of the 10 largest domestic timber industry plants. It manufactures equipment under the Altai trademark.

The range of sawmills produced is huge. It includes disk and belt units. The first ones are equipped with a circular saw with victorious solders or with set teeth. The cutting attachment is mounted on the shaft of the electric motor or on the spindle of the equipment. For the operation of such machines, a connection to a three-phase network is required.

Advantages of Altai circular sawmills:

• the possibility of fast and high-quality processing of wood with a smooth surface;
• precise sawing - the output is lumber with technical parameters precisely specified by the operator;
• low energy consumption with high productivity;
• compactness;
• the ability to disassemble equipment, making it easy to transport;
• unpretentiousness of the equipment, the possibility of its operation at positive and negative ambient temperatures.

The disadvantages of circular sawmills include their higher price compared to belt-type equipment.... Another significant disadvantage is the impossibility of processing trunks with a large diameter.

Altai band sawmills are most often purchased by small and medium-sized woodworking plants. Horizontal equipment is used for the production of edged and unedged boards of various lengths and thicknesses, veneers, sleepers and other blanks. The working body of such equipment is a band saw, and the basis of the structure is rail guides.

Advantages of "Altai" band sawmills:

• budgetary cost - such machines will cost less than disk machines, thanks to which they are purchased for private use;
• quick installation;
• low consumption of electrical energy;
• the possibility of obtaining a thin cut;
• the ability to cut large tree trunks.

The disadvantages of tape devices include the need for frequent maintenance and the need for fine tuning of technology (otherwise the finished material will be of poor quality).

Professional woodworking equipment for enterprises with different productivity is produced under the Altai trademark.

The assortment includes more than 10 types of band sawmills. The most popular belt-type models are presented below.

• Altai-900... The unit has a simple and reliable design. Due to its low cost, it is often purchased for subsidiary farms and for small businesses. The equipment is allowed to operate around the clock. The "Altai-900" band sawmill has a length of 8500 mm, a width of 1900 mm and a height of 1600 mm. The model provides for electromechanical lifting and lowering of the processed lumber.For the operation of the equipment, a connection to a 380 V electrical network is required.

• Altai-900-proff with a power of 11 kW. Horizontal lathe with a capacity of at least 8 m3 of sawn timber per shift. The maximum diameter of the processed logs is up to 900 mm. The equipment provides for an electromechanical system for lifting the saw unit. The unit has dimensions of 8500x1950x1600 mm (LxBxH, respectively). The weight is 800 kg.

• Altai-700. Equipment for processing logs with a diameter of up to 700 mm and a length of 1 to 6.5 m. The minimum thickness of the lumber obtained at the exit is 2 mm. The machine is equipped with a 7.5 kW electric motor. Manual movement of the bar along the rail base is provided. The total weight of the equipment is 700 kg.

The Altaylestekhmash company also produces band sawmills equipped with internal combustion engines (ICE). Such devices, in comparison with electrical ones, are distinguished by simpler and faster repair. Units with internal combustion engines are considered mobile, since they are allowed to operate at the site of felling. Popular gasoline models include the following: Altai-700A, Altai-900A-prof (both have a Honda engine).

Models are available in several types, depending on the size of the mounted saw blade. Here are the most common patterns.

• Altai-DPA550. This is a double saw machine equipped with 2 discs of 550 mm. The power of the electric motor is 2x11 kW, the voltage is 380 V. The dimensions of the machine (without a rail track) are 1400x1860x1400 mm. The length of the rails is 10500 mm. Unit weight - 750 kg, productivity - 10-12 m3 of sawn timber per shift.

• Altai-DPU600... Angle saw machine equipped with 2 saw blades perpendicular to each other. The model has an automatic feed of the saw material. The saw carriage has the ability to move horizontally and vertically. The equipment is designed for processing barrels with a diameter of no more than 800 mm.

For safety reasons, before performing work on any types of sawmills "Altai" you should carefully read the instruction manual. Failure to follow the manufacturer's recommendations may result in accidents. The operator must wear a variety of personal protective equipment when operating the equipment. These include overalls, goggles, respirator, comfortable shoes. It is recommended to refrain from wearing jewelry, loose suits and other things that can accidentally get into moving parts of equipment.

Electric sawmills must be operated in a room with a well-thought-out ventilation system. The workplace should be well lit and not cluttered with foreign objects. To reduce the risk of electric shock, equipment must be grounded. The machines must be operated in dry rooms. It is not allowed to use the unit in conditions of high humidity, in the rain. To prevent the unit from failing prematurely, it should not be overloaded - all work must be performed in the modes recommended by the manufacturer.

Leaving the switched-on machine unattended is unacceptable. Before leaving, turn off the equipment, turn off the power. In this case, you need to wait until the pulleys come to a complete stop. Before switching on the device, it is important to avoid sudden start-up. To do this, before connecting the equipment to the network, make sure that the switch is in the off position.

For trouble-free operation of the machine, it is recommended its regular maintenance (lubrication of moving machinery). Before any maintenance and repair work, the sawmill must be disconnected from the electrical network.
