In the room, the four wheeled mobile hydraulic lifting platform can be used to hang slogans, banners, replace the special effects lights, such as the layout of high-altitude booth.

在室内，四轮移动式液压升降平台可以用来悬挂宣传标语、横幅、更换特效灯、布置高空展台等。

The T700-GE-701C has better high altitude and hot weather performance, greater lifting capacity, and improved corrosion protection.

T700 - GE - 701c的高海拔高温性能较好，提升能力更强，抗腐蚀能力也有所增强。
