API SE 350 Casing Elevator/Spider

The Casing Elevator/Spider Units are pneumatically operated power tools, capable of hanlding casing sizes from 4 1/2 to 24 1/2 inches, with string loads of 3150kN for the 350 ton unit, 4500kNfor the 500 ton unit, 6672kNfor the 750 ton unit.

 

These units have been refined and incorporate such engineering features as air powered operation with safety latch, and four independent slips, as standard equipment.

 

The main bodies can be dressed as a casing elevator or spider. The elevator consists of an upper unit using a bell guide and bottom guide. The lower unit is dressed as a Spider with a top guide that centers the Spider over the master bushing.

 

The elevator is attached to the derrick traveling block and hook with 350 or 500 ton standard API links. The Spider locates directly on the pin drive master bushing (27 1/2 MSPC, 37 1/2 and 49 1/2 MPCH), and square drive master bushing (271/2 MSS), and will accommodate any other master bushing when used with an Adapter Plate.

 

The Elevator/Spider operates form a single, 2 position control lever that raises and lowers the slips. The slips are suspended on two inter-locking leveling beams that are driven by four air cylinders. This feature allows the slips to operate in synchronization in both the set and raised positions, while permitting the cylinders to work together so no one cylinder overrides any other, causing misalignment and binding. A manual override system is also provided in the event of a temporary loss of rig air pressure.

 

The pneumatic system incorporates a filter-regulator, which regulates and filters the rig air and reduces the pressure to the requirements of the Elevator/Spider system. The air is sent to the control valve that operates the leveling beams. As directed by the control lever, the air cylinder will raise or lower the slips attached to the leveling beam.

 

The direct airs lift and lock mechanism enables instant actuation of the slips. In offshore or land operations this allows the derrick man or the men on the floor to raise and lock the slips, or lower the slips in the elevator or spider instantly.
