Product Description Simple Chain Type Hydraulic JackPRODUCT OVERVIEW~ LYT-type hoist is composed of one-stage double-acting hydraulic cylinder, pulley block, load-bearing chain and oil way etc.~ Moveable pulley is used to enlarge chain stroke, i.e. traveling distance of the cylinder is 1/2 of lifting distance of the chain.~ It applies to inverted installation and construction of various large storage tanks (steel) and various storage tanks.~ LYT-type chain-type hydraulic hoist includes the following models: LYT-120-2700, LYT-200-2700, and LYT-300-2700 etc. (those with special stroke need to be customized).

LYT-type hydraulic hoist is used to firstly lift the tank roof and the top (first layer) siding of the tank. It's required to group weld tank siding when the lifting height of siding exceeds the second siding (the second layer from the top) by 30-50mm, and group weld the third layer (the third layer from the top to the bottom) of the tank after lifting again, lift successively, group weld the siding of the tank layer by layer, until the last layer of siding.2. LYT-type hydraulic hoist is used for lifting. When oil enters the hydraulic jack, the movable pulley is pushed upward by pressing the piston, thus driving the load-bearing chain to lift the expansion ring. In this way, the whole tank (including tank roof) is lifted up, until it reaches the pre-set height (there is a voidance of the next layer of plate). The siding in this layer is surrounded for butt welding. After the positioning block is welded, hydraulic hoist returns and the lift tank falls back to the newly-surrounded siding. After welding of circular seam and vertical seam, the door-type card for fixing expansion ring is cut off and the expansion ring is released. In this way, the hoist returns and expansion ring falls to the Model of hydraulic pump station.Tank volume Rated pressure Rated flow Power Control voltage of solenoid valve Motor drive rate YB-7.2 220L(700*550*580) 25Mpa 7.2L/min Three-phase Four-wire(380V) 220V 5.5KW YB-14.5 340L(750*650*650) 25Mpa 14.5L/min 220V 7.5KW Mode of LYT-type hoist.Rated lifting capacity (KN) Hydraulic area (mm) Rated oil pressure (MPa) Piston stroke (mm) Chain stroke (mm) Cylinder safety equipment Reinforcement measures LYT-120-2700 120 11304 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods LYT-200-2700 200 18859.6 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods LYT-300-2700 300 25434 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods bottom of tank siding. Then, the next circular plate is expanded and transfer rib plate, such as door-type card, is welded for lifting, and so forth. The group welded tank is lift,until group weld of the last layer of siding, so that the whole storage tank is installed with this inverted method.★Advantages of Inverted Hydraulic on Improving Large Construction Storage Tank1. Hydraulic lifting is stable, safe and reliable. Due to the adoption of unified hydraulic control and single or partial (several) adjustment, the whole lifting process is relatively stable. The hoist is provided with synchronizing valve and hydraulic lock to prevent sliding and falling of the tank or heavy loads, which are caused by power failure and fracture of oil tube. Hydraulic lifting is stable, safe and reliable.2. Construction quality is ensured. As the hoist is provided with synchronizer and adjustable function, lifting height can be controlled accurately. Due to above reasons, quality of the tank is ensured. 3. The equipment is easy to operate. Construction environment is good and work efficiency is high. 4. The equipment is well-adapted. As long as the number of hydraulic hoists is increased or decreased, the whole set of equipment can be applied to the inverted hydraulic lifting construction of large storage tanks with different volumes ranging from several thousand cubic meters to tens of thousands cubic meters. 5. The hydraulic pump station and the hydraulic hoist are placed in the tank for easy operation. Finally, a door-closing plate is reserved to move the equipment out of the storage tank, and the door-closing plate is group welded well. 6. The hydraulic pump station can be controlled singly or jointly, and has strong construction adaptability and excellent technical performance price ratio. 7. Short construction period, low cost and good economic benefit. Due to the high degree of modernization and the fast lifting speed of the complete set of equipment, it has low construction cost and good economic benefit. This technology is truly characterized with convenient and centralized control, simple operation, safety and reliability (no falling), accurate control of weld clearance and lifting height of heavy objects, which can ensure the quality of the project, save labor and reduce costs, and achieve remarkable economic benefits.
