Product introduction

Floor spring is a hydraulic closer, its device which stress the spring is worm gear, not wheel gear.

Because worm gear can rotate both side, so floor spring can use for two way opening door, and door closer only use for single direction opening door. The key technique of floor spring is the bottom bearing plate, it decide the bearing level of the floor spring. Compare to door closer, two way opening door’s floor spring need to bear door’s weight, so floor spring choosing is depend on the weight of door.

In practical use, door leaf’s weight will not above normal range, so the door’s width and wind pressure are the main element. Another notice is the proportion of the width and height, if the proportion is not good, door leaf can not use normally.

From the view of producing, floor spring’s worm gear structure make it compress rate smaller than wheel gear, floor spring’s closing arm is shorter, so floor spring’s quality depends on the design of structure and precise producing.
