German dorma tools dorma models dorma prices

dorma tools are material handling equipment for lifting or jacking heavy loads, operating intermittently to raise weights. Most lifting tools begin a vertical or combined vertical and horizontal travel cycle after the rigging picks up the load, unload at the destination, return empty to the pickup point to complete one work cycle, and then proceed to the second lift. Generally, during operation, picking up, moving, and unloading are performed sequentially, with the corresponding mechanisms working intermittently. Lifting tools are mainly used to handle piece goods; when equipped with grabs, they can handle bulk materials such as coal, ore, and grain; when equipped with ladles, 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 serves as the primary operational tool; for example, cranes for loading and unloading materials at ports and stations are the main operational tools.

dorma tool types

1) Frame saw. Also known as a sash saw, it consists of an H-shaped wooden frame, twisted rope and toggle, saw blade, etc. 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 twisted tight, the 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 lumber. Medium saw blades are 550—650mm long, with a tooth pitch of 3—4mm; medium saws are mainly used for cutting 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 cutting finer wood and cutting tenon shoulders. 2) Knife saw. A knife saw mainly consists of a cutting edge and a handle, and can be divided into single-sided, double-sided, back-backed knife saws, etc. 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 cutting and the other for cross cutting. Back-backed knife saws have a plate length of 250—300mm; the back of the blade is straightened with a steel strip, the teeth are finer, and they are available as rip or cross cut saws. 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 cutting 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 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, curves, and other shapes. 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 two ends; serrated edges are cut into the wire, using the sharp edges for 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.

dorma tool precautions

Large saws are commonly used for wide and thick boards; small saws are used for narrow and thin lumber; coarse saws are commonly used for cross-cutting; fine saws are used for tenons and shoulders; saws with greater set are used for hardwoods and wet wood, while saws with less set are used for softwoods and dry wood. When using, safety operating procedures for various saws must be observed: 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 straight and 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 a few times. Do not apply excessive force; do not twist left or right during cutting; apply downward pressure on the push stroke and lift lightly on the return stroke, maintaining a uniform rhythm; when nearing the end of the cut, hold the piece to be severed steady with your hand. Relax the blade tension after use 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 off towards the side with greater force; when correcting a skewed cut, do so slowly to prevent binding or breaking the blade. 3) When using a wire saw, do not pull too forcefully or too quickly to avoid breaking the wire. When sawing, 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 blade and the stability of the saw frame and handle; promptly repair blades with dull or uneven teeth, and repair or replace damaged ropes, nuts, knobs, handles, and wooden frames before continuing use.

dorma 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, 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 ground connection. The power cord shall be a multi-core soft rubber-sheathed cable, with the ground protection wire securely connected at both ends. 3) Handheld power tools should be operated by dedicated personnel with appropriate professional knowledge. Strictly adhere to relevant safety operating procedures during use. 4) Before use, check that related 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 dedicated personnel. 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 in 1957, also known as local vibration disease, typically manifesting as episodic white finger.
