Joint lifting operation, pincers worker and the defect for playing the more cumbersome operations of people's compounding practice of heavy industry are hung, but is individually grasped by a pincers worker
Make one and half gantry cranes, piston rod, which can be completed, using suspender belt lifting plunger end turns over operation, easy to operate, substantial saved
Driving resource securely and reliably improves operating efficiency and utilization rate of equipment and installations.
2, the tooling for being installed on piston rod head has carried out effectively the nozzle on cooler pan during piston rod turns over
Protection.
3, the front and back contact surface with support stick of bolt hole of the installation of two copper backings and piston rod head, is turned in piston rod
In operation process, it is effectively protected the mounting surface of piston rod.
4, the support stick and bolt hole are coordinated using small―gap suture, and diameter is substantially at close-fitting shape with bolt hole aperture
State avoids bolt hole of damaging during lifting by crane to be effectively protected bolt bore edges.
5, the material hardness of support stick avoids the damage to piston rod less than piston rod.
In short, the utility model improves operating efficiency, saving is utilized scene driving resource, has easy to operate, peace
Complete reliable and convenient and efficient advantage.
