They should utilize a mechanical lifting device (e.g., block and tackle, hoist, or crane) secured to an overhead support, such as a portable tripod, capable of supporting the weight.

他们应该利用机械起重装置（如滑轮和滑车、卷扬机或起重机），起重装置要固定在能够承受容器重量的高架支撑上，如移动三脚架。

When the bottom touches the ground, the stroke switch can make the hoisting machine to stop running, so as to guarantee the wire rope not loosen, and make wire rope of the roller list in order to avoid rope loosen and in disorder.

当吊笼底部刚刚接触地面时，行程开关动作，可使卷扬机自动停止运行，从而保证钢丝绳不会呈松弛状态，并使卷扬机卷筒钢丝绳始终排列整齐，避免松绳和乱绳。

The large size slide valve , seal structure was introduced.

The key point of the structure of the utility model is that: the other side of the reducer that is arranged on the platform is provided with a hoisting device; the roller shaft end of the electronic controlled windlass is provided with a hub, a damper brake is arranged outside the hub; the input castellated shaft of the reducer that is arranged on the electronic windlass is provided with duplicate gears that have different amount of teeth.

本实用新型包括标准节，两侧标准节的中间为平台，电控卷扬机的卷绳通过平台上的滑轮同吊盘相连；平台上的减速器的一侧设置有可提升平台的具有卷绳的滚筒，平台上设置有具有滑轮的支架，其结构要点平台上的减速器的另一侧设置有提升装置；电控卷扬机的滚筒轴端设置有轮毂，轮毂外设置有制动闸；电控卷扬机的减速器的输入花键轴上设置具有不同齿数的双连齿轮，双连齿轮之间的凹槽内的拨杆同减速器外的摇把相连。

Winch the type of construction, structure, design, calculation and application we need to fully understand that the overall design of the building winch, from various parts described the choice of the main electrical power, the transmission ratio calculation and validation; reducer design; rope's choose including the selection of a rope, use and reel in the fixed reel; reel involved in the calculations, the design and structure commonly used materials, rope reel capacity size parameters; is the last of the clutch and brake design, the main cone used friction with brake and clutch.

建筑卷扬机的种类、结构、设计、计算及应用需要我们充分的了解，在对建筑卷扬机的总体设计中，从各个部件出发，主要叙述了电动机功率选择、总传动比计算与校验；减速器的设计；钢丝绳的选择包括了钢丝绳的选取、使用及在卷筒上的固定；卷筒的设计计算涉及卷筒结构和常用材料、卷筒容绳尺寸参数；最后是有关离合器与制动器的设计，主要采用了圆锥摩擦离合器和带式制动器。

Derrick on Tianlun and rope set up the runway, the installation of hoists, winches double (3t) double rope traction, transport staff and lining materials; hoists the runway with a winch (2t) to tighten, In addition, the site symmetry at the bottom of the derrick cantilever mast for two, with two winches (3t) upgrading of materials, two separate winch (1t) Luffing operation.

井架上设天轮和钢丝绳跑道，装置吊笼，用双卷扬机（3t ）双绳牵引，运输人员和内衬材料；吊笼跑道用一台卷扬机（2t ）收紧，另外，在井架底部对称部位设悬臂桅杆两台，用两台卷扬机（3t ）提升物料，另设两台卷扬机（1t ）变幅操作。

And the JTS series Speed Adjustable Hoisters are the digital circuit controlled,fully automatic hoisters.

JTP 系列调速卷扬机是我公司最新开发的新一代电脑控制的全自动智能化产品，JTS系列调速卷扬机为数字电路控制的全自动卷扬机。

Whenever Tess lifted her head she beheld always the great upgrown straw-stack, with the men in shirt-sleeves upon it, against the gray north sky; in front of it the long red elevator like a Jacob's ladder, on which a perpetual stream of threshed straw ascended, a yellow river running up-hill, and spouting out on the top of the rick.

苔丝每次抬头看见的，都是那个越堆越高的麦秆垛，看见站在垛顶上的那个只穿衬衣的男工，突现在北方的灰色天空里。麦垛的前面有一架长长的红色卷扬机，好像雅各梦见的梯子①一样，麦粒被脱掉了的麦草像流水一样顺着卷扬机源源而上，就像是一条黄色河流，流到了山上，喷洒在麦秆垛的顶上。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
