English to Chinese Other Mechanics / Mech Engineering

全句是：Allowance for higher belt tensions caused by thicker and/or wider belts must also be taken into consideration. 试着译了两个版本，但都不确定：1 传送带张力会随传送带的厚度和/或宽度的增加而增加，这一点必须考虑在内.2 必须考虑传送带张力可以随其厚度和/或宽度的增加而增加的限度。其前文是：A reinforced 3-stage gearbox and stronger bearings give the **** the ability to fulfil the increased requirements of heavy unit handling applications at low speeds, high torques and high belt tensions.The decision whether to use a *** or a ****should be made primarily on the calculated belt tension (T1+T2) plus any expected shock loading. （*为产品型号）供背景参考。多谢！
