摘要： An interference with existing structures is prevented at a time of a lifting construction of a boiler module. When the boiler module is lifted from the ground by lifting jacks provided on a steel frame main-beam and made an install construction to the main-beam, lifting jacks enabled to move laterally on the main-beam are disposed at forward and backward thereof to suspend the boiler module. The suspended module is lifted up to the main-beam and installed while changing a suspending position between an interference preventing position with existing modules and a prescribed suspending position by alternately moving the forward and backward lifting jacks laterally.

摘要： A jacking system includes a wheeled hydraulic power unit having an operating handle, and at least two extendable jack units which are identical.Each jack unit is adapted to rest upon the ground, and the power unit can be wheeled into (or out of) engagement with the jack unit. When engaged with a jack unit, the power unit is capable of extending (or raising) the jack unit; a ratchet on the jack unit then locks it in its extended position. A manual control on the power unit is coupled to the jack unit (when the two units are interengaged) for releasing the ratchet, so that the power unit can then lower the jack stand to its retracted position.

摘要： A mobile power unit for a jacking system having extendible members is disclosed. The unit includes a frame having a pair of lifting members each having an extension member mounted therein and a pair of tie-rods each connected between the frame and the extension members to move the extension members progressively forward as the lifting members are raised. A pair of guides each having a slot are mounted on each of the lifting members to maintain the top of a jack stand at a constant angular relation with the extension members. The device also includes an alignment mechanism having a pair of curved springs each mounted on one of two arms of the frame and a pair of associated protuberances each mounted on opposite parallel walls of the jack stand to align the jack stand at a predetermined location on the frame. A release mechanism for releasing the jack stand has two cams each mounted on one of the two arms of the frame and a pair of pins each mounted to extend outwardly from opposite ends of the jack stand. The cams are normally spring-biased in their non-engaging position.A control cord is connected to each of the cams to rotate them to engage the associated pin to lower the jack stand.

摘要： A jacking apparatus and method for effecting movement of loads. At least two double-acting hydraulic cylinders including a first and a second cylinder arranged in tandem provide increased force for a power stroke of the apparatus. Hydraulic fluid pressure is provided at a predetermined flow rate to the group of hydraulic cylinders. Substantially all of the predetermined flow rate of hydraulic fluid is routed to the first hydraulic cylinder to provide increased speed for a repositioning stroke of the apparatus.

摘要： A chain jack utilizing two chains is operated by alternately transferring e chain load from latches incorporated within an upper latch assembly to latches incorporated within a lower latch assembly while moving the upper and lower latch assemblies away from and toward each other by alternate extension and retraction of a hydraulic ram to cause relative movement between the chain and the lower latch assembly. Actuation of the latch mechanism is controlled by hydraulic connection to a pair of four-way valves operated by a control piston having followers from the four-way valves engageable thereon. The control piston is disposed to move with the upper latch assembly while the followers are rigidly affixed to the lower latch assembly. Thus, the engagement and disengagement of the latch mechanisms with the chains are synchronized by the relative movement between the lower and upper latch assemblies.

摘要： A chain jack is operated by alternately transferring the chain load from a cylinder or base latch mechanism to a ram head latch mechanism and moving the base and the ram head away from and toward each other by alternate extension and retraction of the ram to cause relative movement between the chain and the base. The chain load is sequentially supported first by one latch and then the other; one latch cannot be disengaged from the chain unless the other is supporting the load. Actuation of the latches is controlled by hydraulic connection to valves operated by cams and followers in a side arm and fixed element arrangement whose relative movement is synchronized with movement between the base and the ram to control high pressure liquid flow to latch actuating hydraulic cylinders.
