German ARROW tools ARROW models ARROW prices

ARROW tools are material handling tools for lifting or jacking heavy loads, operating intermittently to lift weights. Most lifting tools begin a vertical or combined vertical and horizontal working stroke after the rigging picks up the load, unload at the destination, then return empty to the pickup point to complete one work cycle before performing the second lift. Generally, during operation, lifting tools perform picking, moving, and unloading sequentially, with the corresponding mechanisms working intermittently. Lifting tools are mainly used to handle piece goods; equipped with a grab bucket, they can handle bulk materials such as coal, ore, and grain; equipped with a ladle, they can lift liquid materials such as molten steel. Some lifting tools, such as elevators, can also be used to carry people. In certain application scenarios, lifting equipment is the primary working tool; for example, cranes for loading and unloading materials at ports and stations are the primary working tools.

ARROW tool types

1) Frame saw. Also known as a sash saw, it consists of an H-shaped wooden frame, twisted rope and twist pieces, and a saw blade. The two 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 the rope is tightened, the blade is taut 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 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. A knife saw mainly consists of a saw edge and a handle, and can be classified into single-sided, double-sided, and back-backed knife saws. Single-sided knife saws are 350mm long, 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 are 300mm long, with teeth on both sides; typically, one side is for rip cutting and the other for cross cutting. Back-backed knife saw plates are 250—300mm long; the back of the blade is straightened with a steel strip, and the teeth are finer, available in rip and cross cut versions. 3) Groove saw. A groove saw consists of a handle and a 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 blade, with the blade being approximately 250—750mm long and a tooth pitch of 3—4mm; panel saws are mainly used for sawing wider boards. 5) Narrow hand saw. The blade is narrow and long, with a pointed tip, and a length of approximately 300—400mm. Narrow hand saws are mainly used for sawing 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 sawing 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, using the sharp edges for sawing. The wire is approximately 200—600mm long, and the saw bow is 800—900mm long. Wire saws are mainly used for sawing complex curves and cutting holes.

ARROW tool selection

Precautions for selecting power tools: First, a power tool is a handheld or portable mechanized tool powered by an electric motor or electromagnet, driving the working head through a transmission mechanism. Power tools feature portability, simple operation, and diverse functions, significantly reducing labor intensity, improving work efficiency, and mechanizing manual operations. Therefore, they are widely used in construction, home decoration, automotive, machinery, electric power, bridges, gardening, and other fields, and have extensively entered households. Power tools are characterized by lightweight structure, small size, light weight, low vibration, low noise, flexible operation, ease of control and operation, portability, robustness, and durability. Compared to manual tools, they can increase labor productivity by several to dozens of times; compared to pneumatic tools, they offer higher efficiency, lower costs, and easier control.

ARROW tool usage

1) Non-sparking tools provide safety assurance for personnel working in flammable, explosive, and corrosive environments, enhancing social safety and allowing workers to operate with greater peace of mind. After daily use, non-sparking tools require proper maintenance, which is crucial for their service life; improper maintenance may prevent the tools from serving us for a long time. First, store the tools in a dry place to prevent damage to working components. In daily work, after 20 consecutive strikes, surface deposits on the tools should be cleaned off before reuse. Do not use continuously, as prolonged friction may cause the tools to overheat, potentially damaging the product. 2) After use, wipe clean surface dirt and deposits, and store in a dry, safe place. 3) For striking tools, do not strike continuously; allow appropriate intervals after more than ten strikes, and promptly remove debris adhering to the product before continuing use. 4) Wrenches must not be used with excessive force; do not extend the lever arm using sleeves or by binding other metal rods, and do not use a hammer to tighten fasteners (except for strike wrenches). 5) Cutting-edge tools should be gently touched against a grinding wheel in a water trough for sharpening; avoid excessive force and prolonged contact with the grinding wheel. 6) During actual operation of chipping and striking tools, clear site debris and corrosive oxides from the working surface to prevent third-party impacts. Based on the above performance and usage, aluminum-copper alloys are more suitable for normal pressure equipment and environments with less stringent explosion-proof requirements (such as gas stations and small oil depots). Beryllium-copper alloy non-sparking tools are suitable for applications such as refineries, gas transfer stations, gas production plants, and drilling teams. 7) Remove surface oil stains before using various products, and refer to the instructions for steel tools for usage.
