升降机

When power is transmitted to the elevator shaft, it drives the splined center wheel and the planetary mechanism which consists of three planetary wheels forming 120 degrees with each other and the inner gears drives the drum to rotate, the hoisting band brake is combined with the hoisting disc, and the drum's left ring is combined with the braking band brake, then the elevator has three status: hoisting, braking, and lowering down.

当动力传至升降机轴后，轴带动与花键联接的中心轮，三个互成120度的行心轮及内齿圈组成的行星机构，使卷筒回转，提升抱闸与提升盘结合，卷筒左端外圈与制动抱闸结合，这样升降机具有提升、制动、下降三种工作状态。

This would even include a wheel chair stair lift and portable wheelchair lifts and even a wheelchair platform lift.

这将甚至还包括轮椅座椅电梯和便携式轮椅升降机，甚至坐轮椅平台升降机。

Strong commercial construction has created a ground swell of demand for small rough-terrain scissor lifts that can put tradesmen within reach of three- and four-story work. Contractors need scissor lifts that perform like RT booms on the site before there is a concrete slab or power to recharge batteries to keep pace with building development.

坚固的商业建筑使得可将作业人员升举到三四层高度的小型不平地面剪式升降机的需求越来越大，承包商需要与RT起重臂性能相类似的剪式升降机，然后出现混凝土板以及可对电池进行重新充电的动力源，以此来保持与建筑发展齐头并进。

According to the characters of the stage lifter ,we have innovatively applied the movable pulley mechanism to it,which is of simple construction, low cost and easily to manipulate.

This article tends to design a new system with 4-level elevating speed which could realize the design demands on the basis of existing fix-shaft planet-wheel system elevator. In this article , instead of changing the ubiety among the parts of the original elevator , the author keeps on using the original structure.

当前，岩心钻机升降机主要使用定轴式行星轮系升降机，本文就是在已有的定轴式行星轮系升降机的基础上，设计出能够实现设计要求的四档提升速度的升降机。

At present, rock driller elevator mostly betakes fix-shaft planet-wheel system elevator. This article tends to design a new system with 4-level elevating speed which could realize the design demands on the basis of existing fix-shaft planet-wheel system elevator.

For the purpose of researching the factors which affect the dynamic characteristic of mast of builder's hoist and analyzing the impact of different factors over system security, the authors of the paper applied the finite element method to build the model and made the modal analysis for mast which was installed with various installation distances or under different working conditions.

目的 探讨影响施工升降机导轨架结构动态特性的因素，分析不同因素对结构安全性的影响。方法采用有限元方法，建立了施工升降机导轨架等有限元模型，并对吊笼运行不同工况以及多种附着装置安装间距下的导轨架结构进行模态分析。

The company has experienced technical staff and senior engineer, the main production of hydraulic lifts fixed, mobile hydraulic lifts, vehicle-mounted hydraulic lifts, fixed-board hydraulic axles, mobile hydraulic Deng Axle , Huoti fixed snorkels, and other products, according to customer demand and production design of a variety of purposes, the different specifications of the hydraulic lifting machinery.

本公司拥有一批经验丰富的技术人员和高级工程师，主要生产固定式液压升降机、移动式液压升降机、车载式液压升降机、固定式液压登车桥、移动式液压登车桥、固定式液压升降货梯等系列产品，并可根据客户需求设计生产各种用途、不同规格的液压升降机械。

Indeed Skyjack abandoned its venerable differential drive system on its 68RT line to make an RT scissors with 32 feet of platform height, for example, retract down to a 69-inch stowed height.

商业建筑的诱惑力非常大，以致于大多数主要剪式升降机制造商- Genie、Haulotte、MEC和Skyjack都在过去的18个月里引入了新型RT剪式升降机。

One side of a reducer that is arranged on the platform is provided with a roller which can hoist the platform and which is provided with a rolling rope.

建筑施工升降机属于建筑机械领域，特别涉及一种施工升降机。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
