TL多功能器械系列,是我国首创的最新力量训练器械。它根据液压控制的原理,通过旋钮自动控制练习阻力和速度,运动员可以在器械上任意选择“定力”、“等动”、“静力”三种不同性质的力量练习,故具有既能定力又能调速的多功能特点。一、研制概况八十年代初,美国首先出现了液压等动练习器械,1981年,美国“克瑟”公司制造了CAM—Ⅱ系列的气压器械,按力
TL multi-functional equipment series, is China’s first new strength training equipment. According to the principle of hydraulic control, it automatically controls the resistance and speed through the knobs. The athlete can choose three different kinds of strength exercises such as “fixed force”, “equal movement” and “static force” on the instrument. Therefore, Power and speed control of the multi-function features. First, the development overview In the early eighties, the United States first appeared hydraulic reciprocating practice equipment, in 1981, the United States, “Kerosene” CAM-Ⅱ series of manufacturing pressure equipment, by force
