German KLEINMICHEL tools KLEINMICHEL models KLEINMICHEL prices

KLEINMICHEL tools are material handling tools for lifting or jacking heavy loads, a type of intermittent-duty tool for lifting heavy objects. Most lifting tools begin vertical or combined vertical and horizontal travel after the lifting gear 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, picking up, moving, and unloading are carried out sequentially, and the work of the corresponding mechanisms is intermittent. Lifting tools are mainly used to handle piece goods; when equipped with a grab bucket, they can handle bulk materials such as coal, ore, and grain; when 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.

KLEINMICHEL tool types

1) Frame saw. Also known as a rack saw, it consists of an I-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 saw blade. 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 based on saw 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 lumber. Medium saw blades are 550—650mm long, with a tooth pitch of 3—4mm; medium saws are mainly used for sawing thin lumber 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 two parts: the saw edge and the saw handle. It can be divided into single-sided, double-sided, and back-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. Back-backed knife saws have a blade plate length of 250—300mm; the back of the back-backed knife saw is straightened with a steel strip, and the teeth are finer, available in rip and cross cut types. 3) Groove saw. A groove saw consists of a handle and a saw blade, with the blade 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 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 saw blade is narrow and long, with a pointed front end, approximately 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 construction is the same as that of a frame saw, but the saw blade is narrower (approximately 10mm), mainly used for sawing arcs, curves, and other sections. 7) Wire saw. Also known as a bow saw, it is made by bending a bamboo strip into a bow shape and stretching wire between the two ends. Saw-toothed edges are cut into the wire, using the sharp edges of these teeth 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.

KLEINMICHEL tool precautions

Large saws are commonly used for wide and thick boards; small saws are commonly used for narrow and thin lumber; coarse saws are commonly used for cross-cutting; fine saws are commonly used for tenons and shoulders; saws with greater set are required for hardwoods and wet wood, while saws with less set are required for softwoods and dry wood. When using, you must pay attention to the safe operating methods for various types of saws: 1) Before using a frame saw, first adjust the angle of the saw blade with the knob; conventionally, it should form an angle of 45° with the plane of the wooden frame. Tighten the tensioning rope with the twist piece to make the saw blade taut and tight. When starting the cut, hold the saw handle firmly with your right hand and place your left hand at the starting point, gently pushing and pulling a few times. Do not apply excessive force; do not twist left or right during sawing; apply more pressure on the push stroke and less on the pull stroke, maintaining a uniform rhythm; when nearly finished, hold the part being cut off steady with your hand. After use, loosen the saw blade and hang it in a secure location. 2) When using a crosscut saw, apply balanced force with both hands to prevent the saw from running toward the side with greater force; when correcting a skewed cut, correct it slowly to prevent binding or breaking the saw blade. 3) When using a wire saw, do not apply excessive force, and do not pull too quickly, to avoid breaking the wire. When pulling the saw, the operator's head must not be positioned above the top of the bow frame to avoid facial injury from snapping wire. 4) Regularly check the sharpness of the saw blade and the firmness of the saw frame and handle; promptly repair saw blades with dull or unevenly set teeth, and promptly repair or restore damaged ropes, nuts, knobs, handles, and wooden frames before continuing use.

KLEINMICHEL tool usage

1) Carefully inspect before use; ensure there is no external damage, switches operate flexibly without sticking, and power cords and tool housings are intact. Use a 500V megohmmeter to measure the insulation resistance between the winding and the housing; it must not be less than O.5 megohms. See the attached table for insulation resistance values. 2) Handheld power tools with metal housings must have a reliable protective grounding connection. The power cord is a multi-core soft rubber-sheathed cable, and its grounding protection wire must be securely connected at both ends. 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, first check whether the relevant electrical and mechanical protective devices are intact and functioning normally. Also ensure that 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 appropriate 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 syndrome 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.
