German testo tools testo models testo prices

testo 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, lifting tools perform picking, moving, and unloading in sequence, and the operation of each corresponding mechanism is intermittent. 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.

testo 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. Both ends of the saw blade are fixed to the frame with knobs, which can be used to adjust the angle of the blade. After the rope is twisted tight, 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 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 saw handle, and can be classified 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-cut and cross-cut types. 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 blade plate length of 250—300mm; the back of the blade is straightened with a steel strip, the teeth are finer, and they are available in rip-cut and cross-cut versions. 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 sawing wider wooden boards. 5) Narrow hand saw. The saw blade is narrow and long, with a pointed front end, 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), and it is mainly used for sawing 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 and stretching a steel wire between the two ends; serrated edges are cut into the steel wire, using the sharp edges of these serrations for sawing. The steel 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.

testo tool selection

1) Distinguish between household and professional use according to needs. Most power tools are designed for professionals; when purchasing, distinguish between professional and general household tools. The difference between professional and general household tools usually lies in power; professional tools have higher power to reduce the workload for professionals. Since household tasks are smaller and the workload is relatively lower, the input power of household tools does not need to be very high. 2) The outer packaging of the tool should have clear patterns, no damage, a sturdy plastic box, and durable latches for opening the plastic box. 3) The appearance of the tool should have uniform color; the surface of plastic parts should have no visible flow marks or indentations, and no scratches or impact marks. The assembly misalignment between housing parts should be ≤0.5mm. Aluminum casting coatings should be smooth, aesthetically pleasing, and free of defects. The entire unit surface should be free of oil and stains. When held by hand, the switch handle should be flat. The cable length should generally be no less than 2 meters. 4) The nameplate parameters of the tool should match those on the CCC certificate. The manual should include the detailed address and contact information of the manufacturer and production plant. The nameplate or certificate of conformity should include a traceable batch number for the product. 5) Hold the tool by hand, connect to power, and frequently operate the switch to start the tool repeatedly. Observe whether the on/off function of the tool switch is reliable. At the same time, observe whether there are any abnormalities in nearby televisions or fluorescent lights to confirm whether the tool is equipped with an effective radio interference suppressor. 6) Run the tool under power for one minute. While running, hold it by hand; you should not feel any abnormal vibration. Observe the commutation sparks; the commutation spark level should not exceed level 3/2. Generally, looking inward from the air inlet of the tool, there should be no obvious arcing on the commutator surface. During operation, there should be no abnormal noise.

testo tool features

The electronically controlled powerful chuck has extremely strong holding force, up to 16kg/cm², with uniform and adjustable magnetic distribution, suitable for various heavy machining, rough machining, and precision machining operations. Ordinary powerful chucks have weaker and uneven holding force, unable to meet the requirements of heavy machining operations. The holding force of an electronically controlled powerful chuck does not require a continuous power connection to maintain; it generates no heat during continuous operation, avoiding thermal deformation of the workpiece. Meanwhile, the strong and uniform surface holding force ensures the highest machining precision even if the workpiece overhangs the table. In contrast, ordinary electromagnetic chucks require a continuous supply of current to maintain magnetic force, generating heat after a period of operation. This not only causes thermal deformation of the workpiece but also reduces the chuck's magnetic force, failing to guarantee machining precision. Electronically controlled powerful chucks can be used continuously; even if operated continuously for more than 20 hours per day, no failures will occur, and no maintenance is required. Ordinary permanent magnet chucks may experience a decline in holding force after about half a year of use, while electromagnetic chucks can only operate for a few hours per day and are prone to malfunctions, requiring frequent replacement and repair of internal components. Using ordinary powerful chucks requires significant workpiece adjustment time, accounting for 40%-50% of the entire machining process, and clamping positioning is prone to obvious errors, resulting in a high scrap rate and very low efficiency. Electronically controlled powerful chucks feature automatic auxiliary positioning; simply pressing a button completes workpiece clamping or release in 0.3 seconds, significantly improving production efficiency.
