Product Description

All screw jacks in the series can be manually operated. The maximum load that can be handled according to the reduction ratio of screw jacks. Obviously, greater loads can be manually handled by applying further reductions to the screw jack or by increasing the radius of the handwheel.
Hand wheels are available for Linear Power Jack so that it can be easily used for manual operation. Hand wheels are used for self-lock equipped Linear Power Jacks (Machine Screw Type) only. Because Linear Power Jacks (Ball Screw Type) and Linear Power Jacks (High Lead Screw Type) are not equipped with a self-lock, the input shaft may be reversed by a load, therefore, it is dangerous to use the hand wheel. Hand wheel efficiency is determined by the required torque for a specified load and the diameter of the hand wheel. Also, vibration and shock may cause self-lock failure, in which case a brake unit is recommended. 



All JACTON screw jacks with handwheels are ideal solutions for applications where electricity or power generators is inconvenient or dangerous, light weight, low duty cycle, low target cost and short travel length. Available in load capacity 1/4 ton, 1/2 ton, 1 ton, 2 ton, 2.5 ton, 3 ton, 5 ton, 10 ton, 15 ton and 20 ton, heavy load larger than 20 ton capacity, handwheel manual operation is not recommended. There are two types hand wheels, one is cast iron handwheels, another aluminum handwheels. The cast iron handwheels sizes 100mm, 125mm, 160mm, 200mm, 250mm, 300mm, 400mm and 500mm. The aluminum handwheels sizes 100mm, 125mm, 160mm, 200mm.
We offers complete systems to meet your requirements. Customers have depending on us to specify their system components for decades. Just tell us what you need, and we can provide the technical support to successfully size your lifting system. We offers the most comprehensive support for customers requiring multi-jack lifting and positioning systems.

Pillow blocks and flange blocks are important components in jack and actuator systems. They are sometimes needed to support long shafts or the ends of rotating screws. We Ductile iron pillow blocks and flange blocks include self-aligning replaceable bearings that are pre-lubricated with lithium grease. They include steel retainers, and nitrile rubber seals with steel guards. They are suitable for use under normal duty operation.
Couplings are important components in jack and actuator systems and it is important to select the best option based on torque and rotational speed requirements.
Line Shafting is an important component in jack and actuator systems and it is important to select the best option based on torque and rotational speed requirements. Contact We with your questions and, as a complimentary service, we will help you specify the compatible components for a complete system. 
Helical/Worm gear reducers are important components in jack and actuator systems and it is important to select the best option based on torque requirements. 
Miter gear boxes are specifically engineered for use with We jacks and Actuators in multiple jack systems. Miter gear boxes used in systems effectively raise unevenly distributed loads. All standard miter boxes are available in 1:1 and 2:1 ratios; other ratios are available too. Four shaft units are also available too.
Protective boots are available as an option for We Jacks and Actuators. They protect the lifting screw from dust, dirt, and help maintain proper lubrication. Standard boots, fabricated from neoprene-coated nylon, also guard against moisture and corrosive materials. Adding boots may increase the closed height of the jack or actuator, depending on the end condition and the amount of travel (rise) required.

Encoder combines with your control system to monitor screw travel, number of revolutions, and travel limits. The shaft-mounted encoder offers easy installation, proven reliability and virtually maintenance-free operation. It includes a six-pin connector, worm shaft coupling, and mounting adapter. 
Mechanical counters for screw jacks and actuators. These allow position tracking for manual operations. These convert the rotational movement of the input shaft into a numeric readout at the counter. It is important to know the size of increments to be measured and the number of decimal places to be measured and displayed.
Hand wheels in a variety of diameters. They are recommended for self-locking jacks and actuators and can be mounted directly to the jack input shaft. Since hand wheels are are mounted directly onto jacks and actuators and specified as part of the complete jack part number. Their specific selection is dependent on input torque requirements.
Geared potentiometers are ideal for precise positioning applications. Geared potentiometers are available with upper and lower mechanical limit switches. Since geared potentiometers are mounted directly onto jacks and actuators and their specific selection is dependent on ratio and rise, they are specified as part of the complete part number.
Trunnion adapter plates bolt to the base of 0.25-ton through 20-ton machine screw or ball screw jacks. They include precision bores for trunnion pins. These are frequently used in installations where a single jack moves through an arc during operation. This jack is often configured with a motor mount.
