This document summarizes the results of safety testing and verification conducted on the wing door automatic lock and release device, "Seesaw Catch." The strength is equal to or greater than that of existing manual locking devices, and it operates even if the vehicle twists due to road surface or cargo conditions. In this case, it has been verified through technical data and safety assessments that no excessive load is applied to the seesaw catch and wing panel during the opening and closing of the wing. 【Overview of Safety Tests】 ■ Static Tensile Load Test After the seesaw catch is installed on a transport truck and subjected to an off-center load, the load-bearing capacity is measured using a precision universal testing machine. ■ Dynamic Stress Measurement The seesaw catch is installed on a transport truck to recreate various road surface conditions. The stress acting during the opening and closing of the wing is measured using a dynamic strain gauge. *For more details, please download the PDF or feel free to contact us.

The "Coming Rack" is an electric hydraulic tailgate opening and closing device that allows for the opening, closing, and securing of the tailgate with just a button operation, providing strong support for loading and unloading tasks. We offer two types to match the body shape: standard and reinforced. The standard type can easily open and close a tailgate that is 9.6m long, 1.2m high, and weighs approximately 220kg (made of aluminum block), which is among the largest classes for large trucks. With the reinforced type, using two units on one side allows for the easy opening and closing of a tailgate made of square pipe weighing 900kg. The Coming Rack gently supports the rapidly increasing number of female and elderly drivers, contributing to safe and comfortable loading and unloading operations and driving tasks. 【Features】 ■ The driver only needs to operate the tailgate opening and closing button ■ If equipped with an auto catcher, the locking and unlocking of the tailgate can also be done automatically ■ With the reinforced type, very heavy tailgates made of square pipe can be opened and closed safely ■ Opening and closing can be performed without entering the swing range of the tailgate ■ Prevents serious personal accidents caused by sudden drops of the tailgate or cargo shifts *For more details, please refer to the PDF document or feel free to contact us.

The 'Seesaw Catch' is an automatic wing door release and lock device that allows for the release and locking of the wing with just a button operation by equipping it on vehicles with wing-type roofs. When opening and closing the wing, there is no need to operate the device one by one, making it easy and user-friendly for female drivers and elderly drivers. It can be easily installed by anyone, regardless of whether the vehicle is new or used. In addition to preventing operational mistakes and accidents or injuries during operation, it significantly reduces the time and effort required for loading and unloading tasks (shortening the time by more than one minute for each opening and closing). [Features] ■ Increases work efficiency by automating the wing lock device ■ Eliminates operational mistakes, achieving standardization of on-site work ■ Prevents accidents and injuries during operation ■ Easy installation regardless of whether the vehicle is new or used ■ Patent obtained (Patent No. 3095742) *For more details, please refer to the PDF materials or feel free to contact us.
