Brief: Electric Screw Jack can also be called motorized screw jack, it includes a worm gear screw jack and an electric motor.The screw jack can be self-locking acme screw jack or high precision ball screw jack.The motor can be high precision servo motor,stepper motor,helical gear motor, worm gear motor, 3-phase asynchronous motor and 12v,24v,48v do motor and dc gear motor etc.
Brief: Worm gear screw jacks ( classic and cubical), quick lifting bevel gear screw jacks, Bevel gear boxes can be used as either single drive units or multi lifting systems. Multi lifting Equipment are generally driven by a single motor. This makes the system to lift Equal. When driven by two or more motors sophisticated electrical synchronization and control is required.
Brief: Screw Jacks Linear Actuators and lifting jack is an electric motor. Screw jacks come assembled, threaded, and ready for hookup. Connect a motor or hand-crank shaft to the screw jack shaft to lift, hold, position, and level loads. This is achieved like this: an electric motor drives a worm shaft that causes a worm gear to rotate. The worm gear is provided with a threaded spindle (standard: trapezoidal thread; special version: ball screw) – and the Screw jack is finished.
Brief: Screw jacks should not be driven to their mechanical limits and stroke limit switches can be supplied. Increased protection is available using bellows or a stainless steel screw. Multi-jack lifting systems use 2, 3 or 4 jacks. For reasons of synchronization, it is usual to employ a single geared motor, often with a double output shaft such as is possible with a helical bevel design. Connection between the screw jacks is made by spacer couplings and bevel gearboxes. Ideally the screw jack supplier will take responsibility for the specification and supply of the complete lifting system.
Brief: Servo motor mounts for 2.5-ton, 3-ton, 5-ton, and 10-ton worm gear screw jacks and electric cylinders. Easily attach the motor of your choice to either side of your jack. These mounts are compatible with various servo motors. Motor mounts allow direct coupling to the motor shaft on either the right or the left side of the jack input shaft. For easy installation 2-ton through 20-ton jacks are available with motor mount adapters for standard IEC, or NEMA C-faced motors. Jacks supplied with motor mounts are available with and without IEC, or NEMA c-faced motors. When motors are included they come with the necessary hardware and coupling keys.
Brief: Electric motorized driven screw jack are used for rivers, canals, power station sluice gate lifting projects in Australia and Vietnam, which uses electric motor driven instead of human power starting with a simple manual operation screw jacks. Motorized Single unit, pair units...multiple units or tandem screw jack arrangements with kinds of motors for gates. Selecting correct screw jack models following sluice gate sizes, gate weight, gate friction force, water pressure, water impact force, required travel speed etc. Sluice gate is an important application for screw jack mechanism,the mechanism can be manual or electric motor driven.
Brief: Screw jacks are suited for lifting, lowering, pushing, pulling and pressing. They can be operated manually or by electric, hydraulic or pneumatic motor. Worm gear screw jacks provide a lifting force of up to 100 tons, a spindle length of up to 10 meters and achieve lifting speeds of up to 0.05 m/s. (higher lifting speeds upon request). Screw gears are designed according to a modular concept allowing for any combination and variation required. On request, screw jacks can be manufactured from rust-free materials to permit use even under extreme chemical stress.
Brief: Electric motor lifting device: A lifting device consists of an electric motor, a gearbox and a drum with a cable for lifting a mass. Overload safety couplings are used to reduce electric screw jack and motorized screw lifting system damage, repairs and downtime by acting as torque limiters and overload protection. In the event of excessive torque the safety function disengages and the motor gets separated from the motorized screw jack drive system. Overload safety couplings are a life insurance for electric and motorized screw jack or lifting systems, no matter whether the error is due to incorrect operation, faulty programming, material overload or tool breakage.
Brief: All standard motors are 3-phase, 50 Hz., 380 VAC. Other single phase or three phase motors options are available. Maximum 1500 RPM input. Brake motors are recommended for double lead jacks, ball screw jacks and actuators, and electric cylinders that are more than 30% efficient. It is important to consider the input torque a direct drive motor must deliver at start up. If the motor frequency will be varied to provide a "soft" start, an inverter duty motor may be needed.
Brief: Motorized-Electric screw jack allowable voltage,phases and hertz includes 380V-3 Phases-50HZ, 220V-3 Phases-50HZ, 400V-3 Phases-50HZ, 415V-3 Phases-50HZ, 440V-3 Phases-50HZ, 480V-3 Phases-50HZ, 220V-3 Phases-60HZ, 240V-3 Phases-60HZ, 480V-3 Phases-60HZ, 110V-Single Phase-60HZ, 120V-Single Phase-60HZ, 220V-Single Phase-50HZ, 230V-Single Phase-50HZ, 240V-Single Phase-50HZ. For special application, for example solar tracker industry, most of engineers or designers prefer to use 24V, 36V, 48V DC motor with gear reducer direct connected worm gear screw jack.
Brief: Screw jacks can be connected directly to an electric motor creating a compact linear drive. Standard 3 phase motors are most common. For lower powers DC motors can be used, or servo motors can achieve high performance. Worm gear screw jacks versions - Rotating screw: Driven by a precision worm gearing (screw keyed to the worm wheel), the rotary motion of the screw is translated into linear motion of the travelling nut on the screw. Trapezoidal screw For tough conditions, good price/performance ratio.
Brief: The level of adjustment accuracy depends mainly on the precision of the screw. Positioning accuracy is influenced, in the case of motor-actuated units, by the electrical control and regulating system, the control system of the brake, and by the adjustment precision of the limit switches. Select schematic drive-system layout: Number and arrangement of screw jacks, type of motor, connecting shafts, bevel gear boxes, couplings.
Brief: The motorized or reducible screwed jack is designed so that motor and shaft connection can be made in both directions. The choice of gear unit type, motor type and interconnection shaft types (according) to the load and materials to be lifted is determined by our company. The choice of X and Y type is determined by our company according to the requested pace and according to the specifications stated in the order form and the best efficiency and also performance is ensured.

Brief: Single drive unit: Worm gear screw jack-coupling-motor in configuration B3 (base-mounted), and Worm gear screw jack-coupling-IEC flange in configuration B14 or B5 (IEC flange-mounting). Worm gear screw jacks and quick-lifting screw jacks can be used as either single drive units or multi-screw lifting systems. Multi-screw lifting systems with mechanical synchronization are driven by a single motor, which makes them impervious to unequal load distribution and its negative effects on the synchronization of the screw jacks.
Brief: Multi-screw lifting systems with electrical synchronization are distinguished by their low requirements in terms of mechanical connecting elements (and therefore lack of running noise), but they do require more sophisticated controls. Precise configuration of the drive motors, in conjunction with a master-slave layout, produces the corresponding exact synchronization of the drive systems. Once you have decided on the best layout for your needs, you can establish which bevel gear boxes, couplings and connecting shafts are to be fitted. The fitting of pillow blocks can multiply the speed dependent length of the connecting shafts.
Brief: For screw jacks and general gearbox applications where no brake is required, or used with a self-locking gearbox ratio. With mechanical brake fitted from factory. For screw jack and gearbox secondary safety applications and for position holding for ballscrews and spindles. In order to remove and pick up loads, electric motor spindle lifting gears are used especially with ball screws. Due to their higher degree of efficiency and pitch they guarantee an optimal automation process with the important factors "efficiency" and "repeat accuracy". Thus, heavy loads can be moved by employees in an easier and safer way.
Brief: Many programs for the operation of canals that deliver water to the agricultural community involve the mechanization of canal gates. Gate screw jacks provide a method of raising and lowering canal gates using electric motors driven instead of human power operated. motorized screw jack for sluice gate, is popular on the world water power projects.
