1. 鋼鎖式液壓頂升 Steel lock hydraulic jacking

鋼索式液壓提升裝置是以液壓油為動力，推動液壓缸活塞往復運動，使與活塞上端連接的上卡緊機構和與缸體下部連接的下卡緊機構之間進行載荷轉換，從而實現提升(或下降)重物的一種新型、特殊的起吊設備。因為選用結構形式為1×7-Φ15.2的高強度預應力鋼絞線作為卡緊機構內的承力件，故定名為"鋼索式液壓提升裝置"，以漢語拼音字頭"GYT-**型"表示。

一套設備由結構相同的四臺液壓千斤頂、二臺液壓泵站和一個電器控制柜等主要部套件組成。組合形式為一臺液壓泵站驅動二臺千斤頂，相互之間用高壓膠管及信號電纜連接，組成一個單元，共二個單元。二個單元通過控制電纜與電器控制柜連接，有電器控制柜進行集中控制，既可二組聯動，也可以單組運行。系統基本配置為四個千斤頂單元，可通過擴展實現八、十二個單元及多單元同步集群控制。

到目前為止，該設備已完成國內大型建筑和電力建設項目500余項(吊重10-2000t，吊高10-270m)。實踐證明，鋼索式液壓提升裝置廣泛適用于大型設備的起吊、安裝和張緊。

The Steel lock hydraulic jacking device uses hydraulic oil as the power to push the piston of the hydraulic cylinder to replace movement, so that the upper clamping mechanism connected to the upper end of the piston and the lower clamping mechanism connected to the lower part of the cylinder are gradually converted to achieve lifting ( (Or drop) a new type of special lifting equipment for heavy objects. Because the alternative structure is 1×7-Φ15.2 high-strength pre-stressed steel strands as the internal load-bearing parts of the clamping mechanism, it is named ". Steel cable hydraulic lifting device" with the initials of Chinese pinyin" GYT-** type" means.

A set of equipment consists of four hydraulic jacks with the same structure, two hydraulic pump stations and an electrical control cabinet. The combination form is that one hydraulic pump station drives two jacks, which are connected with each other by high-pressure hoses and signal cables to form a unit, with a total of two units. The two units are connected to the electrical control cabinet through the control cable, and the electrical control cabinet is centrally controlled, which can be linked by two groups or run in a single group. The basic configuration of the system is four jack units, which can be expanded to realize synchronous conversion control of eight or twelve units and multiple units.

Facts have proved that the steel cable hydraulic lifting device is widely used for the lifting of large-scale equipment. When installed, the equipment has completed more than 500 large-scale construction and power construction projects (lifting weight 10-2000t, lifting height 10-270m). And tensioned.
