The Type Ddz Elevator is a centre‑latch lifting device featuring an 18‑degree tapered shoulder, engineered for demanding petroleum drilling operations. Constructed from high‑strength alloy steel grade AISI 4140/4340, it complies with API Spec 8C for drilling and production hoisting equipment. Load capacity spans from 100 tonnes up to 750 tonnes, and the elevator accommodates pipe and tubing diameters between 2 3⁄8 in and 6 5⁄8 in. The tapered‑shoulder geometry provides enhanced load distribution for larger‑diameter tubulars.
The alloy grade delivers a typical tensile strength of about 1150 MPa, consistent with industry practice for AISI 4140/4340 used in high‑load hoisting gear. Standard machining tolerances for the bore and tapered shoulder are ±0.005 in, ensuring reliable fit across a range of pipe sizes. Heat‑treatment followed by quench‑tempering is a typical surface‑hardening process to increase fatigue life. These attributes match the conventional specifications for heavy‑duty oilfield elevators worldwide.
These elevators are sourced by drilling contractors, oil‑field service companies and equipment distributors operating in both on‑shore and offshore projects. Buyers often arrange bulk deliveries packed in wooden crates and negotiate Incoterms such as FOB or CIF depending on site logistics. The listing does not disclose a minimum order quantity, so prospective purchasers should confirm MOQ directly with the supplier. Payment is generally structured through an irrevocable Letter of Credit, subject to the supplier’s credit terms.

Before confirming a purchase, importers should ensure the elevators meet API Spec 8C and request the material test and heat‑treatment certificates. Verify that the 18‑degree tapered shoulder dimensions and load rating align with the intended drilling programme, and obtain a dimensional drawing to avoid installation issues. It is also prudent to ask for evidence of any third‑party quality audits or inspection records the supplier may have performed.
Shipping these heavy elevators usually requires a 20‑ft or 40‑ft container with the units secured in wooden crates. The supplier does not list a production lead‑time, so buyers need to ask for a detailed schedule and expected departure date. Commonly used Incoterms include FOB Rudong Port or CIF destination, and payment is typically arranged via irrevocable Letter of Credit after the supplier’s credit assessment.
A pre‑shipment inspection by an independent agency is recommended to confirm dimensional tolerances, surface finish and load‑test results. Upon receipt, a non‑destructive examination such as ultrasonic testing should be carried out to detect any internal defects. All relevant certificates - material test, heat‑treatment, API compliance and inspection reports - must be retained for customs clearance and future warranty claims.
