WEIGHT BALANCER AND PIPE JOINING METHOD

摘要

The present invention relates to a weight balancer and a pipe joining method that is capable of reducing a load of pipes when arranging and welding the pipes in ships, plants, piping work sites and the like. A weight balancer according to the present invention includes an operation plate for putting an alignment object; a plurality of load cells installed in the lower portion of the operation plate; a controller which receives a detection signal generated from the load cell and analyses the information of the alignment object to generate a control signal; an operation force driver which receives the control signal from the controller to control an operational pressure of each of a plurality of pressure supply lines; and a plurality of leveling cylinders and balancing devices which are connected to the pressure supply lines to control a location or pose of the operation plate so as to correspond to the size of the operational pressure controlled by the operation force driver.
