Everything you need to know about Side Door SLX Series Elevators | Keystone Energy

As a manufacturer of a variety of Drilling Elevators, we thought that it might be helpful to share with you everything that we think you might want to know about Side Door SLX Series Elevators

About Side Door SLX Series Elevators

Side Door SLX Series Elevators are used to maneuver drill collars and casing. Side Door SLX Series Elevators can generally handle all types of casing up to 42 inches. And, their load rating ranges from 65 to 500 tons. 

Unlike Square Shoulder and Bottleneck Elevators which close at the center, SLX Elevators have their doors positioned to the side. In order to prevent the elevator from accidentally opening during operation, there are some safety redundancies including a latch, safety latch, and safety pin which is attached with a cable that is affixed to the elevator.

To open the elevator; remove the safety pin, pull the latch lock handle outward, and pull open the two elevator halves. 

API Certified Equipment

To ensure that you are receiving a quality elevator it is highly recommended that you only buy API certified equipment. The American Petroleum Institute (API) licenses “Drilling and Production Hoisting Equipment” manufacturers under API Spec 8C, which covers elevator links, tubing and drill pipe elevators, sucker rod elevators, spiders (if capable of being used as elevators) and various other types of handling tools.

API is a globally recognized certification and licensing leader in various industries, and also has extensive experience licensing and certifying regular elevators as well. Any manufacturer with the API seal of approval is compliant with API standards and has the proven capability to manufacture to API Product Specification Requirements. 

Purchasing equipment from a supplier with API Certification ensures you are buying quality equipment that meets API industry standards.

Routine Inspection Of Side Door SLX Series Elevators

Of all the tools on a drilling rig, elevators are one of the most stressed pieces of equipment. Due to this, they require regular inspection. KET's operation manual lays out the necessary inspections that must be performed for optimum performance.

There are 2 types of inspections the MRA and TMA Operating manual advise--daily inspections and inspections every 6 months.

Proper Elevator Inspection

  1. Visually inspects for cracks, loose fits or connections, and other signs of wear, corrosion or overloading.
  2. Check for loose or missing components, deterioration, proper lubrication, and adjustment.
  3. Check for worn hinge pin, latch pin and latch lock pin. These may inhibit proper closing of  the door and latch lock engagement.
  4. Check for proper operation of Latch Stop mechanism. The Latch should not stop against the door when closed but have no more than ¼” of standoff from the door.
  5. Check springs for damage, deformation and lack of tension.
  6. Check link block bolts for nuts and cotter pins.
  7. Lubricate the elevator regularly during usage and storage to prevent corrosion.  Use an extreme pressure, multi-purpose, lithium base grease of No. 1 or No. 2 consistency or a lubricant that meets MIL-SPEC-A907E.

**When greasing of pins make sure to pump grease until it comes out of both ends.**

Periodic Actions/Examinations Chart

We recommend to maintain the elevator as prescribed below in the periodic Actions/Examinations chart.Tool maintenance chart MRA

6 Month Inspections

Every 6 months a full NDT (Non-Destructive Testing) inspection of all primary-load carrying components should be performed as defined by the manufacture, in addition to the daily checks specified above.

Replacement Parts

Only KET manufactured parts should be used on KET Elevators.

Upon noticing damaged parts, you should contact Keystone to talk with a sales rep. to discuss and order the proper parts.

It is important to remember that a simple routine visual inspection can end up saving your rig hundreds of thousands of dollars throughout its lifetime, and most importantly help you to keep your team safe.

Verification Process

The verification process documents the steps performed to re-certify the equipment, and are based on evidence that it is capable of operating as intended.
