German ortlieb tools ortlieb models ortlieb prices

ortlieb tools are material handling tools for lifting or jacking heavy loads, operating intermittently to lift 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 performing the second lift. Generally, during operation, lifting tools perform picking, moving, and unloading sequentially, with the corresponding mechanisms working intermittently. 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 serves as the primary working tool; for example, cranes for loading and unloading materials at ports and stations are the main working tools.

ortlieb tool structure and composition

The function of the power element is to convert the mechanical energy of the prime mover into the pressure energy of the fluid. This refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The structural forms of hydraulic pumps generally include gear pumps, vane pumps, and piston pumps. The function of the actuator (such as hydraulic cylinders and hydraulic motors) is to convert the pressure energy of the fluid into mechanical energy, driving the load to perform linear reciprocating motion or rotary motion. Control elements (i.e., various hydraulic valves) control and regulate the pressure, flow rate, and direction of the fluid in the hydraulic system. Depending on the control function, hydraulic valves can be divided into pressure control valves, flow control valves, and directional control valves. Pressure control valves are further divided into relief valves (safety valves), reducing valves, sequence valves, pressure relays, etc.; flow control valves include throttle valves, adjustment valves, and flow divider/collector valves; directional control valves include check valves, pilot-operated check valves, shuttle valves, and directional control valves. Depending on the control method, hydraulic valves can be divided into on/off control valves, fixed-value control valves, and proportional control valves. Auxiliary components include oil tanks, oil filters, oil pipes and pipe fittings, sealing rings, pressure gauges, and oil level/temperature gauges. Hydraulic oil is the working medium that transmits energy in the hydraulic system, including various mineral oils, emulsions, and synthetic hydraulic oils.

ortlieb tool operation

1) The single-phase power cord for mobile electric machinery and handheld power tools must use a three-core soft rubber cable, and the three-phase power cord must use a four-core rubber cable; during wiring, the cable sheath must pass into the equipment's junction box and be secured. 2) Before using power tools, check the following items: the housing and handle must have no cracks or damage; the protective grounding wire or neutral wire connection must be correct and secure; the cable or flexible cord must be intact; the plug must be intact; the switch must operate normally, flexibly, and without damage; electrical protection devices must be intact; mechanical guards must be intact; and rotating parts must move freely. 3) The insulation resistance of power tools should be measured regularly using a megohmmeter of 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 power tools, insulation resistance measurement and insulation withstand voltage tests must be conducted. The test voltage is 380V, and the test duration is 1 minutes. 5) The electrical circuits connecting electric machinery and tools should have separate switches or sockets, and residual current operated protective devices must be installed; the metal housing must 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 protective devices must not exceed 30mA, and the operating time must not exceed 0.1 seconds; the rated residual operating voltage of voltage-type residual current protective devices must not exceed 36V. 7) The operating switch of electric motor-driven tools should be placed within easy reach of the operator. When resting, leaving work, or in case of sudden power outage during work, the power supply side switch should be turned off. 8) When using portable or mobile power tools, wear insulating gloves or stand on an insulating mat; when moving the tool, do not lift it by the power cord or the rotating parts. 9) When using Class III insulated power tools in damp or acid-containing environments, as well as inside metal containers, reliable insulation measures must be taken, and a dedicated supervisor must be assigned. The power tool switch should be located within easy reach of the supervisor. 10) The magnetic surface of magnetic base drills should be flat, clean, and rust-free; when performing side drilling or overhead drilling, measures must 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.
