Heavy duty crank out cantilever rack for oil and gas drill pipes with overhead crane access

In the OCTG (Oil Country Tubular Goods) sector, a damaged thread or a bent drill pipe isn’t just inventory loss—it’s potential rig downtime costing thousands per hour. Stop burying your high-value drill collars and subs at the bottom of a pyramid stack. Our Crank out cantilever rack systems allow for 100% accessibility via overhead crane, ensuring your premium tubulars are retrieved without friction, damage, or dangerous forklift maneuvering.

The Hidden Cost of “Floor Stacking” in OCTG Yards

For decades, maintenance depots and drilling support centers have relied on the “strip and stack” method. You lay down wood dunnage, stack a layer of casing or drill pipe, add more dunnage, and repeat. While cheap upfront, this method is a silent profit killer in the Oil & Gas supply chain.

The problem is the “Last-In, First-Out” (LIFO) nightmare. When a rig calls for a specific 5-inch HWDP (Heavy-Weight Drill Pipe) that happens to be at the bottom of the stack, your yard crew has to move tons of steel to get to it. This “double handling” increases the risk of:

  • Thread Damage: Even with protectors, constant banging of pin and box ends during shuffling leads to galling.
  • Safety Incidents: Roughnecks and yard hands are at high risk of crush injuries when manually guiding forklift tines or slinging unstable loads.
  • Inspection Delays: You can’t visually inspect the straightness or surface condition of a pipe buried three layers deep.

The Solution: 100% Extension for Overhead Crane Access

De Crank out cantilever rack changes the game by turning your static storage into a dynamic retrieval engine. Unlike standard racks that require forklifts to drive into narrow aisles (often damaging the rack or the pipe), our system features retractable arms that extend 100% out into the aisle.

Why “Crane Access” Matters for Drill Pipes

Drill pipes and collars are long, heavy, and round. They are notoriously difficult to balance on forklift tines. The safest way to move them is by slinging them from above using an overhead bridge crane or gantry.

Met onze telescopisch draagrek, you crank the drawer out, and the entire bundle of pipe is exposed vertically. The crane hook drops straight down, slings the load, and lifts it out. There is zero friction between the load being lifted and the pipes stored above or below it.

Technical Specs: Built for the Oilfield

We understand that storing PVC pipe is not the same as storing solid steel drill collars. Our racks are engineered with structural steel I-beams and heavy-duty bearings to withstand the brutal environment of an OCTG yard or machine shop.

Functie Specification for O&G Application Voordeel
Laadvermogen Up to 6,600 – 11,000 lbs (3-5 Tons) per arm level Supports heavy wall drill collars and extensive bundles of casing.
Lengte arm Customizable (Standard 20″ – 48″) Accommodates various pipe diameters without overhang.
Pipe Length 20 ft to 40 ft (Range 2 / Range 3 pipe) Modular columns allow storage of standard joints or longer crossovers.
Protection UHMW / Nylon liners available Prevents metal-on-metal contact, protecting the surface finish of high-alloy pipes.

Organizing Subs, Crossovers, and Pup Joints

It’s not just about the long joints. The drilling floor constantly needs shorter subs, stabilizers, and pup joints. These often get lost in the mix. Our roll-out cantilever racks can be fitted with adjustable dividers.

Safety: Eliminating the “Pinch Point”

In the oil and gas industry, safety is paramount. Traditional pipe racks create dangerous pinch points. When a forklift pushes a bundle of pipes into a slot, if a worker is guiding it, the risk of finger or hand injury is severe.

Onze electric telescopic systems allow the operator to stand at a safe distance and control the racking with a remote. The rack does the heavy lifting, extending the load out to where the crane can grab it safely. This adheres to the “Line of Fire” safety principles strictly enforced on rig sites.

Installation: Anchored for Heavy Loads

Given the weight of drill strings, stability is non-negotiable. Our installation process involves deep anchoring into your facility’s concrete slab. We don’t just set it down; we secure it to withstand the dynamic forces of cranking out 5 tons of steel.

Frequently Asked Questions (O&G Sector)

Q1: Can this rack handle Range 3 drill pipes (approx. 45 ft)?
A: Yes. The system is modular. We simply add more vertical columns to support the length of Range 3 pipes, ensuring there is no sagging or bowing in the middle of the pipe body.

Q2: We use specific thread protectors that add diameter to the pipe ends. Will they fit?
A: Absolutely. We customize the clear height between arm levels based on your specific “box end” diameter with protectors installed, ensuring no snagging when extending the rack.

Q3: Can these be installed outdoors in a pipe yard?
A: Yes, but we recommend our galvanized or specific high-grade powder coating options to resist corrosion from weather and drilling fluids. However, for premium tools, indoor storage is always recommended.

Q4: Is it compatible with magnetic lifters on our crane?
A: Yes. Because the telescoopgiek extends 100%, the overhead space is completely clear. You can lower a magnetic lifter or vacuum lift directly onto the pipe without obstruction.

Q5: How does this compare to “stacking racks” or “bunks”?
A: Stacking racks (bunks) are better than floor stacking but still require a forklift to unstack the top bunks to get to the bottom ones. Our system provides 100% selectivity—you can access the bottom level immediately without moving the top levels.
