jack Product List and Ranking from 38 Manufacturers, Suppliers and Companies

Load-holding gear reducers, winches, and jacks for disaster prevention and disaster response.

Self-locking winches, rack jacks, and reducers can be easily operated manually without power. Lightweight, smart, and compact, they are ideal for disaster preparedness!

We have developed numerous application products equipped with a unique load-holding function (Shoji-lock) that have been well received by our customers. (Patents obtained both domestically and internationally) <Shoji-lock Product Features> - When rotation is applied from the input side, the output side decelerates and transmits power, but rotation is not possible from the output side = self-locking function. This means that it can hold the load at the desired position without the need for brakes. - Compared to worm gear reducers with the same self-locking function, it is highly efficient. Furthermore, while the worm has input and output axes that are orthogonal, our design has the input and output shafts aligned in a straight line (in-line), making it significantly more compact and space-saving, as well as lightweight. - Unlike ratchets or one-way clutches, it can hold the load at any position when motion is stopped, regardless of the direction of rotation. Additionally, there is no ratchet noise, making it suitable for use in quiet environments. - It features a basic sealed structure (IP65) and is maintenance-free. - We offer a variety of application products, including gear reducers that utilize this self-locking mechanism, winches, and linear actuators (rack jacks). We also develop original devices upon request. *For more details, please feel free to contact us.*

The number of adoptions is increasing for rack-type jacks (without screws) with load-holding features.

No need for brakes or stoppers! You can work or conduct experiments while maintaining the position even after stopping the lift. Unlike screws, it offers lightweight operability and is lightweight, smart, and compact!

Unlike conventional screw jacks, this rack-type jack features an overwhelmingly fast ascent and descent speed due to its high efficiency, making it easy to operate. It is equipped with a unique self-locking mechanism that allows it to hold loads without brakes or stoppers, making it a revolutionary jack. In emergencies, it can operate and maintain loads even without a power source. It is available in a manual type with a rated thrust load of 50 kgf. Additionally, it has a large stroke, making it a highly versatile rack jack and linear actuator, suitable for universities, research institutes, and testing facilities. As shown in the photos and videos, when mounted as a lab jack or table lifter, it can hold its position while loaded, and when the handle is turned again, it resumes ascent and descent without any motion delay. (For more details, please refer to our website or catalog.) The basic surface treatment features a black Teflon coating that is resistant to rust. *For more information, please visit our official website or feel free to contact us.

Disaster Response Jack: Can be raised and lowered manually or with a rechargeable electric tool, even without power!

Elevate and stop the work at the desired position to hold the load! This is a disaster prevention rack jack that can be operated manually or with a commercially available electric screwdriver. It can be used even during a power outage!

This is a compact and lightweight rack-type jack (linear actuator) equipped with our company's self-locking mechanism (Shoji-Lock). It holds the load in place while raising and lowering the workpiece. Additionally, it can be restarted from any position without releasing the brake, whether in the upward or downward direction. Due to its lightweight and compact design, it saves space and has been widely adopted and well-received in various fields. Unlike conventional screw jacks, the rack type offers overwhelmingly faster ascent and descent speeds, characterized by its high efficiency and ease of operation. In addition to the manual-only (SLM series) models, there are also electric models (SLE series) that can be driven by power tools such as drill drivers. The surface comes standard with a black Teflon coating that is resistant to rust. It can be widely used for disaster preparedness, energy-saving measures, and defense/military applications. It is also suitable for universities, research institutes, and testing facilities. As shown in the photos and videos, when mounted on a lab jack or table lifter, it can hold its position while loaded, and by turning the handle again, it can resume raising and lowering without any motion delay. It is compatible with commercially available round rack rods (manufactured by KHK). (Rack rods are not included.)
