German DELVAUX tools DELVAUX models DELVAUX prices

DELVAUX tools are material handling tools for lifting or jacking heavy loads, operating intermittently to lift weights. Most lifting tools begin a vertical or combined vertical and horizontal working stroke after the rigging 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, picking up, moving, and unloading are carried out sequentially, and the work 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 usage scenarios, lifting equipment is the primary operating tool; for example, cranes for loading and unloading materials at ports and stations are the primary operating tools.

DELVAUX tool applications and usage

The electric hydraulic oil pump can serve as the hydraulic pump for various hydraulic devices. When paired with other hydraulic tools, the electric hydraulic oil pump can perform tasks such as lifting, pressing, pipe bending, bar bending, straightening, shearing, assembly, and disassembly, reducing labor intensity and improving work efficiency. During use, open the vent nut, open the switch on the oil collection block, connect the power supply, and attach the quick connector to the quick coupling on the associated hydraulic device. Press the power switch; after the motor runs for 1-2 minutes, close the switch to set it to the pressure-boosting state. At this point, the output hydraulic oil will perform various tasks, self-pressurizing as the load increases until 63MPA. After work is completed, open the switch to relieve pressure. Once the hydraulic oil has returned, remove the quick connector, tighten the vent nut, unplug the power cord, and close the switch.

DELVAUX tool structure and composition

The cross-sectional shape and distribution of the magnetic poles vary depending on the workpiece. Common structural types of electromagnetic chucks include rectangular and circular shapes. Rectangular magnetic poles are arranged either longitudinally or transversely. Longitudinal arrangement of rectangular magnetic poles is suitable for securing larger workpieces; transverse arrangement is suitable for securing smaller workpieces. Circular chucks are suitable for securing ring-shaped workpieces or workpieces with complex shapes. 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 small; the direction of magnetic force is perpendicular to the chuck surface and difficult to change, producing only one type of magnetic force for a workpiece with the same contact area; the point of application of magnetic force 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, insufficient clamping force, narrow scope of application, and lower production efficiency.

DELVAUX tool usage

1) Non-sparking tools provide safety assurance for personnel working in flammable, explosive, and corrosive environments, enhancing social safety and allowing workers to operate with greater peace of mind. After daily use, non-sparking tools require proper maintenance, which is critical to their service life; improper maintenance may prevent the tools from serving effectively over the long term. First, store the tools in a dry place to prevent damage to working components. In daily work, after continuous striking 20 times, treat surface deposits on the tools; wipe them clean before reuse. Do not use continuously, as prolonged friction may cause heating and potentially damage the tool products. 2) After use, wipe off surface dirt and deposits, and store in a dry, safe place. 3) For striking tools, do not strike continuously; allow appropriate intervals after ten strikes, and promptly remove adhering debris from the product before continuing use. 4) Do not exceed the rated torque when using wrenches. Do not use sleeves or bind other metal rods to extend the lever arm, and do not use a hammer to tighten fasteners (except for strike-face wrenches). 5) For cutting-edge tools, gently touch the grinding wheel in a water trough for sharpening; do not apply excessive force or maintain contact with the grinding wheel for too long. 6) During actual operation with chiseling and striking tools, clear site debris and corrosive oxides from the working surface to prevent third-party impacts. Based on the above performance and usage, aluminum-copper alloys are more suitable for normal-pressure equipment and environments with less stringent explosion-proof requirements (such as gas stations and small oil depots). Beryllium-copper alloy non-sparking tools are suitable for demanding environments (such as refineries, gas transfer stations, gas extraction plants, and drilling teams). 7) Before using various products, remove surface oil stains and use according to the instructions for steel tools.
