German Fratelli tools Fratelli models Fratelli prices

Fratelli tools are tools that work by using compressed air to drive a pneumatic motor and output kinetic energy. According to their basic operating methods, they can be divided into: 1) rotary type (eccentric movable vane type). 2) reciprocating type (volumetric piston type). General pneumatic tools mainly consist of the power output part, operation form conversion part, intake and exhaust path part, operation start and stop control part, tool housing and other main parts. Of course, pneumatic tool operation must also have an energy supply part, air filtration and pressure regulation part, as well as tool accessories. Main types include impact wrenches (also called pneumatic wrenches, air wrenches, air impact guns), pneumatic screwdrivers (also called pneumatic drivers, air screwdrivers), pneumatic grinders (also called pneumatic polishers, pneumatic wet grinders, pneumatic sanders, pneumatic grinding machines), pneumatic spray guns, pneumatic rivet guns, pneumatic nut setters, air chisels, air hammers, vibration-damped pneumatic saws, and vibration-damped pneumatic files.

Fratelli tool types

1) Frame saw. Also known as a buck saw, it is composed of an I-shaped wooden frame, twisted rope and twist pieces, saw blade, etc. The two ends of the saw blade are fixed to the frame with knobs, and the angle of the saw blade can be adjusted with them. After the twisted rope is tightened, the saw blade is taut and ready for use. Frame saws can be divided into coarse, medium, and fine types according to the length of the saw blade and the tooth pitch. Coarse saw blades are 650—750mm long, with a tooth pitch of 4—5mm. Coarse saws are mainly used for sawing thicker wood; medium saw blades are 550—650mm long, with a tooth pitch of 3—4mm. Medium saws are mainly used for sawing thin wood or cutting tenons; fine saw blades are 450—500mm long, with a tooth pitch of 2—3mm. Fine saws are mainly used for sawing finer wood and cutting tenon shoulders. 2) Knife saw. Knife saws mainly consist of two parts: the saw edge and the saw handle. They can be divided into single-sided, double-sided, back-backed knife saws, etc. Single-sided knife saws are 350mm long, with teeth on one side. According to the different functions of the teeth, they can be divided into rip cuts and cross cuts; double-sided knife saws are 300mm long, with teeth on both sides. The teeth on both sides are generally rip cuts on one side and cross cuts on the other. Back-backed knife saw plates are 250—300mm long. The back of the back-backed knife saw is straightened with steel strips, and the teeth are finer. They are divided into rip cuts and cross cuts. 3) Groove saw. Groove saws consist of a handle and a saw blade. The saw blade is about 200mm long. Groove saws are mainly used for grooving wood. 4) Panel saw. Also known as a hand saw. It consists of a handle and a saw blade. The saw blade is about 250—750mm long, with a tooth pitch of 3—4mm. Panel saws are mainly used for sawing wider wooden boards. 5) Narrow hand saw. The saw blade is narrow and long, with a pointed front end, about 300—400mm in length. Narrow hand saws are mainly used for sawing narrow holes and slots. 6) Coping saw. Also known as a fret saw, its structure is the same as that of a frame saw, but the saw blade is narrower (about 10mm). It is mainly used for sawing arcs, curves, and other parts. 7) Wire saw. Also known as a bow saw, it is made by bending a bamboo strip into a bow shape and stretching steel wire at both ends. Saw-toothed flying edges are chopped onto the steel wire, using the sharp edges of the flying edges for sawing. The steel wire is about 200—600mm long, and the saw bow is 800—900mm long. Wire saws are mainly used for sawing complex curves and opening holes.

Fratelli tool parameters

The most important performance parameters characterizing the basic working capacity of lifting tools are lifting capacity and working class. (1) Lifting capacity refers to the maximum weight of the load allowed to be lifted under specified working conditions, i.e., the rated lifting capacity. Generally, if equipped with a permanent magnet chuck (see permanent magnet lifter), the lifting capacity should also include the weight of the permanent magnet chuck. (2) Working class is a performance parameter reflecting the overall working status of the lifting tool and is an important basis for designing and selecting lifting tools. It is determined by the total number of work cycles required to be completed during the required service period of the lifting tool and the load state. For lifting tools with strong regularity and high repeatability in operation procedures, such as electric hoists for loading and unloading ship cargo at docks, chain hoists for high-bay warehouses, and hopper lifts for supplying blast furnaces, the work cycle is also an important parameter. The work cycle refers to the time required to complete one work cycle, which depends on the working speed of the mechanism and is related to the handling distance. The above-mentioned lifting tools sometimes also use productivity as an important parameter, usually expressed in terms of the amount of lifting completed per hour. In current use, efficiency is the first priority, followed by appearance and quality.

Fratelli tool features

1) Lifting tools are usually small in size, simple in mechanism, and can perform lifting and horizontal movements. 2) The loads lifted by lifting tools vary widely, and the loads are variable. Some heavy objects weigh hundreds of tons or even thousands of tons, some objects are tens of meters long, and their shapes are very irregular, including bulk particles, molten states, flammable and explosive dangerous goods, etc. The lifting process is complex and dangerous. 3) Some lifting tools need to operate within a large spatial range. Some need to be equipped with tracks and wheels (such as tower cranes, bridge cranes, etc.); some need to be equipped with tires or crawlers to walk on the ground (such as truck cranes, crawler cranes, etc.); some need to walk on steel cables (such as passenger and freight aerial ropeways). The activity space is large, and once an accident occurs, the scope of impact is also large. 4) Some lifting tools need to directly carry personnel for lifting movements on guide rails, platforms, or steel cables (such as elevators, lifting platforms, etc.), and their reliability directly affects personal safety. 5) Lifting tools have many exposed and moving parts, and they often come into direct contact with lifting operators (such as hooks, steel cables, etc.), posing many potential accidental danger factors. 6) Complex operating environment. From large integrated steel enterprises to modern ports, construction sites, railway hubs, and tourist attractions, lifting tools are in operation; operating places often encounter dangerous factors such as high temperature, high pressure, flammable and explosive materials, transmission lines, and strong magnetic fields, posing threats to equipment and operators. 7) Lifting tool operations often require the cooperation of multiple people. One operation requires skilled coordination, coordinated actions, and mutual care among command, binding, and driving operators. Operators should have the ability to handle emergency situations on site. Close cooperation among multiple operators is usually quite difficult. The above-mentioned working characteristics of lifting tools determine their significant relationship with safe production. If there is any negligence in the design, manufacturing, installation, use, and maintenance of lifting tools, it may cause casualties or equipment accidents. On the one hand, it causes casualties, and on the other hand, it causes significant economic losses.
