In addition, consider the system stability, reliability, maintainability, safety and efficiency. The stabilizing means when the system works steady motion and system performance stability (such as environmental temperature on the influence of oil etc). Reliability refers to the system is not due to accident reason to work ( such as tubing rupture without electricity, etc. ). Maintainability is referred to the system as simple as possible, element is chosen as far as possible standard parts, structure as much as possible so that the maintenance is convenient. Security is not due to the fault of the hydraulic system causes the antenna frame collapse or other accidents (such as the drop out of control, antenna due to gravity acceleration whereabouts ) . Efficiency refers to the hydraulic system of the various energy loss as small as possible. The above requirements, in addition to meet the power requirements, the most important thing is to ensure the safety and reliability of the system.Keywords: hydraulic system, lifting mechanism目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc351119129 摘 要 PAGEREF _Toc351119129 \h I HYPERLINK \l _Toc351119130 Abstract PAGEREF _Toc351119130 \h II HYPERLINK \l _Toc351119131 目 录 PAGEREF _Toc351119131 \h III HYPERLINK \l _Toc351119132 第1章 绪论 PAGEREF _Toc351119132 \h 1 HYPERLINK \l _Toc
