Soil retention construction gear jack "Super SS Jack"
On-site Non-stop Declaration: Easy! Safe! Speedy! This is the trendy support jack now.
The aluminum gear-type support "Super SS Jack" is an easy-to-extend and retract jack for earth retention work, which can be operated with an electric screwdriver or wrench. With the use of an electric screwdriver, it can be adjusted to the desired extension in about 5 seconds, significantly increasing work speed. The scale display on the jack allows for easy length adjustment at a glance. Unlike conventional hydraulic jacks, it does not require a hydraulic pump, enabling cost savings on anti-rust fluid and antifreeze. It also resolves issues related to construction interruptions caused by water leaks or winter freezing. With its gear structure, there is no worry about the jack shrinking due to water leaks, as is the case with hydraulic jacks. Using a dedicated work rod, it can be installed and removed from the ground without entering the excavation site. It offers a wide range of options suitable for various environments (minimum 390mm to maximum 3200mm), with the ST type featuring a maximum length of 4200mm added to the lineup. 【Features】 ■ Compliant with the earth retention pre-construction method recommended by the Ministry of Health, Labour and Welfare ■ Safe to use in winter without worries about freezing ■ Gear structure makes it less prone to failure and easy to maintain ■ Can be installed and removed from the ground without entering the excavation site using a work rod ■ No shrinking of the jack due to its gear structure! ■ Available for rental (nationwide service)
