German HANHART tools HANHART models HANHART prices

HANHART tools powered by electric motors or electromagnets, driving the working head through a transmission mechanism, are referred to as power tools. These are hand-held tools that use low-power electric motors or electromagnets as their power source, driving the working head via a transmission mechanism. Power tools are categorized into handheld and portable types; handheld power tools offer greater flexibility, convenience, and wider application. Many varieties have become essential tools for production and daily life. With numerous brands available, power tools are primarily classified by function and usage into metal-cutting power tools, grinding power tools, assembly power tools, and railway power tools. Common power tools include electric drills, electric grinders, electric wrenches and electric screwdrivers, electric hammers and impact drills, concrete vibrators, and electric planers.

HANHART tool description

Lifting tools vary in purpose and construction but all feature a hoisting mechanism to perform basic lifting and lowering actions. Materials can be lifted or lowered using flexible components such as wire ropes or lifting chains, or raised using rigid components like screws. Lifting tools are classified by structure into light small-scale lifting equipment, hoists, and overhead monorail systems. Light small-scale lifting equipment mainly includes lifting pulleys, slings, jacks, triangular hand chain hoists, electric hoists, and standard winches. Most are compact, lightweight, and simple to use. Except for electric hoists, most are manually driven and suitable for less demanding tasks. They can be used individually or in combination. Some light small-scale lifting equipment has significant lifting capacity; for example, hydraulic jacks can lift up to 750 tons. Mine hoists and bucket elevators primarily perform vertical or near-vertical lifting along fixed paths. Overhead monorail systems utilize rigid suspended tracks to transport materials to various parts of a workshop and can extend outside the facility.

HANHART tool precautions

Large saws are commonly used for thick, wide boards; small saws for narrow, thin stock; coarse-toothed saws for cross-cutting; fine-toothed saws for tenons and shoulders. Saws with greater set are required for hardwoods and wet wood, while saws with less set are used for softwoods and dry wood. When using saws, adhere to safe operating procedures: 1) Before using a frame saw, adjust the blade angle with the knob; conventionally, it should form an angle of 45° with the plane of the wooden frame. Tighten the tensioning rope with the toggle to keep the blade taut. When starting the cut, hold the handle firmly with the right hand and place the left hand at the starting point, pushing and pulling gently. Avoid excessive force. Do not twist the saw sideways during cutting. Apply more pressure on the push stroke and less on the pull stroke, maintaining a uniform rhythm. Near the end of the cut, stabilize the piece being severed with your hand. After use, release the blade tension and hang the saw in a secure location. 2) When using a crosscut saw, apply balanced force with both hands to prevent the saw from drifting toward the side with greater force. Correct any deviation slowly to avoid binding or breaking the blade. 3) When using a coping saw, do not apply excessive force or saw too quickly to prevent breaking the wire blade. Keep your head away from the top of the bow frame during operation to avoid facial injury if the wire breaks. 4) Regularly check the sharpness of the blade and the stability of the frame and handle. Repair blades with dull or uneven teeth promptly. Fix any damage to ropes, nuts, knobs, handles, or frames before continuing use.

HANHART tool operation

1) Single-phase power cords for portable electric machinery and handheld power tools must use three-core flexible rubber cables; three-phase power cords must use four-core rubber cables. When wiring, the cable sheath must enter the equipment's junction box and be secured. 2) Before using power tools, inspect the following: housings and handles must be free of cracks or damage; protective grounding or neutral connections must be correct and secure; cables or flexible cords must be intact; plugs must be undamaged; switches must operate normally, flexibly, and without defects; electrical protection devices must be functional; mechanical guards must be intact; and rotating parts must move freely. 3) The insulation resistance of power tools should be measured regularly using a megohmmeter rated at 500V. If the insulation resistance between live parts and the housing is less than 2M Ω, maintenance is required. 4) After repairing the electrical components of a power tool, insulation resistance measurement and dielectric strength testing must be performed. The test voltage is 380V, and the test duration is 1 minutes. 5) Electrical circuits for electric machinery and tools must have individual switches or sockets and be equipped with residual current devices (RCDs). Metal housings must be grounded. Connecting multiple devices to a single switch is strictly prohibited. 6) The rated residual operating current for current-type RCDs must not exceed 30mA, and the operating time must not exceed 0.1 seconds. The rated residual operating voltage for voltage-type RCDs must not exceed 36V. 7) Operating switches for motorized tools must be within easy reach of the operator. Disconnect the power supply switch during breaks, at the end of shifts, or in case of sudden power outages. 8) When using portable or mobile power tools, wear insulating gloves or stand on an insulating mat. Do not carry tools by their cords or rotating parts. 9) When using Class III insulated power tools in damp areas, acidic environments, or inside metal containers, reliable insulation measures must be taken, and a dedicated supervisor must be present. The tool's switch must be within the supervisor's reach. 10) The magnetic surface of magnetic base drills must be flat, clean, and rust-free. When drilling sideways or overhead, take measures to prevent the drill from falling in case of power loss. 11) When using electric wrenches, ensure the reaction torque support is securely positioned and the nut is properly engaged before starting.
