German abus tools abus models abus prices

abus tools refer to electrical safety tools, which are various specialized tools and devices designed to prevent accidents such as electric shock, burns, falls, and stumbling, thereby ensuring the personal safety of workers. In power systems, to complete tasks smoothly without personal injury, operators must carry and use various safety tools. For example, electrical safety equipment is required when inspecting operating electrical equipment, changing operating modes, or performing maintenance and tests; climbing safety equipment is needed during line construction; when working on live electrical equipment or in areas near live equipment, insulated safety tools are required to prevent electric shock or arc burns. Electrical safety tools can be divided into four categories: personal protective equipment, insulated safety tools, climbing tools, and warning signs.

abus tool types

1) Frame saw. Also known as a buck saw, it consists of an H-shaped wooden frame, twisted rope and toggle, saw blade, etc. The ends of the saw blade are fixed to the frame with knobs, which can also be used to adjust the angle of the blade. After tightening the twisted rope, the saw blade is tensioned and ready for use. Frame saws are classified into coarse, medium, and fine types based on blade length and tooth pitch. Coarse saw blades are 650—750mm long, with a tooth pitch of 4—5mm; coarse saws are mainly used for cutting thicker wood. Medium saw blades are 550—650mm long, with a tooth pitch of 3—4mm; medium saws are mainly used for cutting 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 cutting finer wood and cutting tenon shoulders. 2) Knife saw. A knife saw mainly consists of a saw edge and a handle, and can be divided into single-sided, double-sided, and backed knife saws. Single-sided knife saws have a blade length of 350mm, with teeth on one side; depending on the function of the teeth, they can be divided into rip cuts and cross cuts. Double-sided knife saws have a blade length of 300mm, with teeth on both sides; typically, one side is for rip cuts and the other for cross cuts. Backed knife saws have a blade plate length of 250—300mm; the back of the blade is reinforced with a steel strip, and the teeth are finer, available for both rip and cross cuts. 3) Groove saw. A groove saw consists of a handle and a saw blade, with the blade being approximately 200mm long. Groove saws are mainly used for cutting grooves in wood. 4) Panel saw. Also known as a hand saw, it consists of a handle and a saw blade, with the blade being approximately 250—750mm long and a tooth pitch of 3—4mm; panel saws are mainly used for cutting wider boards. 5) Keyhole saw. The blade is narrow and long, with a pointed tip, and a length of approximately 300—400mm. Keyhole saws are mainly used for cutting narrow holes and slots. 6) Coping saw. Also known as a fret saw, its construction is similar to that of a frame saw, but the blade is narrower (approximately 10mm), mainly used for cutting arcs and curves. 7) Wire saw. Also known as a bow saw, it is made by bending a bamboo strip into a bow shape with wire stretched between the ends; serrated edges are cut into the wire to perform the cutting. The wire is approximately 200—600mm long, and the saw bow is 800—900mm long. Wire saws are mainly used for cutting complex curves and openings.

abus tool structure and composition

The cross-sectional shape and distribution of the pole cores vary depending on the workpiece. Common structural types of electromagnetic chucks include rectangular and circular configurations. Rectangular magnetic poles are arranged either longitudinally or transversely. Longitudinal arrangement of rectangular magnetic poles is suitable for securing larger workpieces, while transverse arrangement is suitable for securing smaller workpieces. Circular chucks are suitable for securing ring-shaped workpieces or workpieces with complex geometries. The main characteristics of standard electromagnetic chucks are: magnetic flux lines are evenly distributed across the chuck surface, magnetic attraction cannot be concentrated, and the magnetic force per unit area is relatively low; the direction of the magnetic force is perpendicular to the chuck surface and difficult to alter, generating only one type of magnetic force for workpieces with the same contact area; the point of application of the magnetic force on the workpiece is limited to the contact surface between the workpiece and the chuck and cannot be freely adjusted. Therefore, during machining, disadvantages include low positioning accuracy, insufficient clamping force, narrow scope of application, and low production efficiency.

abus tool usage

1) Before use, carefully inspect the tool to ensure there is no external damage, the switch operates flexibly without sticking, and the power cord and housing of the power tool are intact. Use a 500V megohmmeter to measure the insulation resistance between the winding and the housing, which must not be less than O.5 MΩ; see the attached table for insulation resistance values. 2) Handheld power tools with metal housings must have a reliable protective grounding wire. The power cord should be a multi-core soft rubber-sheathed cable, and the grounding protection wire at both ends must be securely connected. 3) Handheld power tools should be used by dedicated personnel with appropriate professional knowledge. Strictly adhere to relevant safety operating procedures during use. 4) Before use, check whether the related electrical and mechanical protection devices are intact and functioning normally. Also ensure that the rotating parts move flexibly without sticking. 5) When using Class I handheld power tools, users must wear prescribed protective equipment and use qualified protective gear. Take corresponding anti-electric shock safety measures as required, such as installing residual current devices (RCDs) in the power circuit, or having the user wear insulating gloves, insulating shoes, or stand on an insulating mat. When using Class II handheld power tools in damp and confined spaces, install a residual current circuit breaker (RCCB) with an operating current of less than 1.5mA and an operating time of less than or equal to 0.1 seconds. The RCCB should be placed inside the container and monitored by a dedicated person. 6) Occupational hazards of using handheld power tools. Arm vibration disease caused by long-term exposure to hand-transmitted vibration was listed as one of China's statutory occupational diseases as early as 1957, also known as local vibration disease, typically manifested as episodic white finger.
