German WOLFCRAFT tools WOLFCRAFT models WOLFCRAFT prices

WOLFCRAFT tools integrate hydraulic systems with conventional tools into a unified whole. They convert powerful hydraulic power into mechanical motions such as reciprocating linear motion, rotary motion, and cycloidal motion. A complete hydraulic tool system consists of five components: power elements, actuating elements, control elements, auxiliary elements, and hydraulic oil. Hydraulic tools include: hydraulic wrenches, electric pumps dedicated to hydraulic wrenches, hydraulic jacks, hydraulic bolt tensioners, hydraulic flange spreaders, hydraulic nut splitters, hydraulic pullers, etc. Hydraulic tools offer the advantages of high efficiency and convenience. A complete hydraulic tool system consists of five components: power elements, actuating elements, control elements, auxiliary elements, and hydraulic oil.

WOLFCRAFT tool classification

1) Screwdriver: A tool used to turn screws to position them, typically featuring a thin wedge-shaped tip that inserts into the slot or recess of the screw head—also known as a "screwdriver". 2) Wrench: A hand tool with an open end or box end that uses the lever principle to turn bolts, screws, nuts, and other threaded fasteners. Wrenches usually have jaws at one or both ends of the handle; applying force to the handle allows turning of the bolt or nut held in the opening or socket. During use, apply force to the handle along the direction of thread rotation to turn the bolt or nut. 3) Hammer: A tool used to strike objects to move or deform them. It is most commonly used to drive nails, straighten, or split objects. Hammers come in various forms; a common form consists of a handle and a head. One side of the head is flat for striking, while the other side is the hammer head. The hammer head can be shaped like a claw for pulling nails, or wedge-shaped. There are also round-headed hammer heads. 4) Test pen: Also called a voltage tester pen, abbreviated as "electric pen". It is an electrical tool used to test whether wires are live. The pen body contains a neon bulb; if the neon bulb lights up during testing, it indicates that the wire is live or is the live wire of a closed circuit. The tip and tail of the test pen are made of metal, while the pen shaft is made of insulating material. When using a test pen, you must touch the metal part at the tail end with your hand; otherwise, because the live object, test pen, human body, and earth do not form a circuit, the neon bulb in the test pen will not light up, leading to a misjudgment that the live object is not energized. 5) Tape measure: A tape measure is a commonly used measuring tool in daily life. Steel tape measures are frequently seen, commonly used in construction and decoration, and are essential household tools. Types include fiber tape measures, leather tapes, waist tapes, etc. Lu Ban rulers, Feng Shui rulers, and Wen Gong rulers also belong to the category of steel tape measures. 6) Utility knife: A type of knife with a sharp blade used to cut wallpaper and similar materials, hence the name "wallpaper knife," also known as a "craft knife". It is frequently used in renovation, decoration, and signboard industries. 7) Electrician's knife: An electrician's knife is a cutting tool commonly used by electricians. A standard electrician's knife consists of a blade, cutting edge, handle, and clip. When not in use, retract the blade into the handle. The root of the blade is hinged to the handle, featuring scale lines and markings; the front end forms a screwdriver tip, both sides have file surfaces, the cutting edge has a concave curved notch ending in a point, and the handle has a protection button to prevent the blade from snapping back. The blade of the electrician's knife integrates multiple functions; only one electrician's knife is needed to perform various wire connection operations without carrying other tools, offering benefits such as simple structure, ease of use, and multifunctionality. 8) Hacksaw: Includes hand saws (for household use, woodworking), pruning saws (for branch trimming), folding saws (for branch trimming), bow saws, veneer saws (woodworking), rip saws (woodworking), and crosscut saws (woodworking). 9) Spirit level: A spirit level contains a bubble vial and can be used to inspect, measure, and debug whether equipment is installed level. 10) Wire pliers: Wire pliers are clamping and cutting tools consisting of a head and handles. The head includes jaws, serrated grips, cutting edges, and shearing blades. The functions of the various parts of the pliers are: (1) The serrated grips can be used to tighten or loosen nuts; (2) The cutting edges can be used to strip the rubber or plastic insulation from soft wires, and also to cut wires and iron wires; (3) The shearing blades can be used to cut harder metal wires such as electrical wires and steel wires; (4) The insulating plastic sleeves on the pliers have a voltage resistance of 500V or higher, allowing live wire cutting. 11) Needle-nose pliers: Also called long-nose pliers, primarily used to cut fine single-strand and multi-strand wires, bend loops on single-strand wire connectors, and strip plastic insulation. They are also one of the commonly used tools for electricians (especially indoor electricians). They consist of pointed tips, cutting edges, and handles. The handles of electrician's needle-nose pliers are fitted with insulating sleeves rated for 500V. Due to their pointed tips, needle-nose pliers are suitable for operations in narrow spaces. The method for bending wire connectors with needle-nose pliers is: first fold the wire end to the left, then bend it clockwise to the right closely against the screw. 12) Wire strippers: Wire strippers are one of the commonly used tools for indoor electricians, motor repair technicians, and instrumentation electricians; their appearance is shown in the figure below. They consist of cutting edges, crimping jaws, and handles. The handles of wire strippers are fitted with insulating sleeves rated for a working voltage of 500V. Wire strippers are suitable for stripping the insulation from plastic and rubber insulated wires and cable cores. The usage method is: place the wire end to be stripped into the blade opening of the head, squeeze the two handles together by hand, then release, and the insulation will separate from the core wire.

WOLFCRAFT tool selection

Precautions for selecting power tools: First, power tools are handheld or portable mechanized tools powered by electric motors or electromagnets, 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, housing decoration, automotive, machinery, electric power, bridges, gardening, and other fields, and have extensively entered households. Characteristics of power tools include lightweight structure, small size, low weight, low vibration, low noise, flexible operation, ease of control and handling, 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.

WOLFCRAFT tool usage

1) Before use, carefully inspect the tool to ensure there is no external damage, the switch operates flexibly without sticking, and the power cord and housing of the power tool are intact. Use a 500V megohmmeter to measure the insulation resistance between the winding and the housing; the value must not be lower 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 wire. The power cord should be a multi-core soft rubber-sheathed cable, and the grounding protection wire at both ends must be securely connected. 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, check whether the related electrical and mechanical protection 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 set up qualified protective gear. Take corresponding 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 narrow spaces, install a leakage switch with a working current of less than 1.5mA and an action time of less than or equal to 0.1 seconds. The leakage switch should be placed inside the container and monitored by a dedicated person. 6) Occupational hazards of using handheld power tools. Arm vibration disease 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.
