German eibenstock tools eibenstock models eibenstock prices

eibenstock tools are material handling equipment for lifting or jacking heavy loads, operating intermittently to raise weights. Most lifting tools begin vertical or combined vertical and horizontal travel after the rigging picks up the load, unload at the destination, then return empty to the pickup point to complete one work cycle before the next lift. Generally, during operation, picking up, moving, and unloading are performed sequentially, with intermittent action of the respective mechanisms. Lifting tools are mainly used for handling 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 carry people. In certain applications, lifting equipment serves as the primary working tool, for example, cranes for loading and unloading materials at ports and stations.

eibenstock tool principles

The principle of hydraulics involves two cylinders of different sizes filled with water or oil. Water-filled systems are called "water presses"; oil-filled systems are called "oil presses." Each cylinder contains a sliding piston. If a specific pressure is applied to the small piston, according to Pascal's law, the small piston transmits this pressure through the fluid to the large piston, lifting it. Let the cross-sectional area of the small piston be S1, and the downward force applied to the small piston be F1. Thus, the pressure exerted by the small piston on the fluid is P=F1/SI, which is transmitted unchanged in all directions through the fluid. The pressure received by the large piston must also equal P. If the cross-sectional area of the large piston is S2, the upward force F2=PxS2 generated by the pressure P on the large piston is a multiple of the small piston's cross-sectional area. From the above equation, applying a small force to the small piston results in a large force on the large piston, which is why hydraulic presses are used for pressing plywood, extracting oil, lifting heavy objects, and forging steel.

eibenstock tool usage

1) Rip cutting method: When sawing, place the wood on a bench, step on the wood with your right foot perpendicular to the cut line, stand straight with your left foot at an angle of 60° to the cut line, keep your right hand perpendicular to your right knee, and position your body at an angle of approximately 45° to the cut line. Lean forward slightly and move naturally, avoiding leaning left or lunging right. Hold the saw with your right hand and place your left thumb against the blade for positioning. Gently pull and push the saw a few times (pull first, then push) to start the kerf, then remove your left hand from the edge. When the teeth have penetrated about 5mm into the wood, use your left hand to assist your right hand in guiding the frame saw. Lift the saw lightly, raising the hand slightly; push the saw with more force, using your wrist, elbow, shoulder, and waist in a rhythmic motion. This ensures the saw follows the cut line. Otherwise, the edge of the rip-cut wood will be curved or uneven. 2) Crosscutting method: When sawing, place the wood on a bench, stand to the rear left of the wood, hold the wood with your left hand, hold the saw with your right hand, and step on the wood with your left foot. The sawing method is the same as for rip cutting. When using a frame saw, the lower end of the blade should tilt forward. For rip sawing, the upper end of the blade tilts backward at an angle of approximately 75°—90° (relative to the wood surface); for crosscutting, the blade tilts backward at an angle of approximately 30°—45°. Always ensure the saw follows the line without deviation. Keep the cut straight; do not allow the blade to wobble left or right. When the wood is nearly severed, stabilize the offcut with your left hand, slow down the sawing speed, and cut completely through. Do not leave any material to break off or snap by hand, as this can damage the saw blade and cause the wood to split along the grain, affecting quality.

eibenstock tool operation

1) The single-phase power cord for mobile electric machinery and handheld electric tools must use a three-core flexible rubber cable, and the three-phase power cord must use a four-core rubber cable; during wiring, the cable sheath shall pass into the equipment's junction box and be secured. 2) Before using electric tools, check the following items: no cracks or damage to the housing or handle; correct and secure connection of the protective grounding wire or neutral wire; intact cable or flexible cord; intact plug; normal, flexible, and undamaged switch operation; intact electrical protection devices; intact mechanical guards; and flexible rotating parts. 3) The insulation resistance of electric tools should be measured regularly using a megohmmeter with 500V; if the insulation resistance between live parts and the housing is less than 2M Ω, maintenance must be performed. 4) After repairing the electrical parts of an electric tool, insulation resistance measurement and dielectric withstand voltage tests must be conducted; the test voltage is 380V, and the test duration is 1 minutes. 5) Electrical circuits connecting electric machinery and tools shall have individual switches or sockets, and residual current operated protective devices shall be installed; the metal housing shall be grounded; it is strictly prohibited to connect multiple devices to a single switch. 6) The rated residual operating current of current-type residual current operated protective devices shall not exceed 30mA, and the operating time shall not exceed 0.1 seconds; the rated residual operating voltage of voltage-type residual current operated protective devices shall not exceed 36V. 7) The operating switch of motor-driven tools shall be placed within easy reach of the operator. During breaks, after work, or in case of sudden power outage during operation, the power supply switch shall be disconnected. 8) When using portable or mobile electric tools, wear insulating gloves or stand on an insulating mat; when moving the tool, do not lift it by the cord or the rotating parts. 9) When using Class III insulated electric tools in damp or acid-containing areas, or inside metal containers, reliable insulation measures must be taken and a dedicated supervisor assigned. The switch of the electric tool shall be located within easy reach of the supervisor. 10) The magnetic surface of a magnetic base drill shall be flat, clean, and rust-free; when performing side drilling or overhead drilling, measures shall be taken to prevent the drill body from falling in case of power loss. 11) When using an electric wrench, ensure the reaction torque support is firmly positioned and the nut is securely tightened before starting.
