Germany baerhausen tools baerhausen models baerhausen prices

baerhausen 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 attachment 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 of lifting tools, picking up, transporting, and unloading are carried out sequentially, and the operation 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 used for loading and unloading materials at ports and stations are the primary working tools.

baerhausen tool principles

The principle of hydraulics consists of two cylinders of different sizes filled with water or oil. Water-filled units are called "water presses"; oil-filled units 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 pressure to the large piston, pushing the large piston upward. 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 can be 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 smaller force to the small piston results in a larger force on the large piston; therefore, hydraulic presses are used for pressing plywood, oil extraction, lifting heavy objects, forging steel, etc.

baerhausen tool structure and composition

The cross-sectional shape and distribution of the pole cores vary depending on the workpiece. Common structural types of electromagnetic chucks include rectangular and circular configurations. Rectangular magnetic poles are arranged either longitudinally or transversely. Longitudinal arrangement of rectangular magnetic poles is suitable for securing larger workpieces, while transverse arrangement is suitable for securing smaller workpieces. Circular chucks are suitable for securing ring-shaped workpieces or workpieces with complex geometries. The main characteristics of standard electromagnetic chucks are: magnetic flux lines are evenly distributed across the chuck surface, magnetic attraction cannot be concentrated, and the magnetic force per unit area is relatively low; the direction of the magnetic force is perpendicular to the chuck surface and difficult to change, generating only one type of magnetic force for workpieces with the same contact area; the point of application of the magnetic force on the workpiece is limited to the contact surface between the workpiece and the chuck and cannot be arbitrarily changed. Therefore, disadvantages during machining include low positioning accuracy, low clamping force, narrow scope of application, and low production efficiency.

baerhausen tool usage

1) Before use, carefully inspect the tool to ensure there is no external damage, switches operate 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 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 conductor. The power cord shall be a multi-core soft rubber-sheathed cable, and its grounding protective conductor must be securely connected at both ends. 3) Handheld power tools shall 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 protection devices and mechanical protection devices are intact and functioning normally. Also ensure that rotating parts rotate flexibly without sticking. 5) When using Class I handheld power tools, users must wear prescribed protective equipment and use 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 confined spaces, install a residual current switch with an operating current less than 1.5mA and an operating time less than or equal to 0.1 seconds. The residual current switch should be placed inside the container and monitored by dedicated personnel. 6) Occupational hazards associated with the use of 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 as early as 1957, also known as local vibration disease, with typical manifestations including episodic white finger.
