The CD side door elevator with square shoulder is a mechanical lifting device designed for handling tubing, casing, drill pipe, and drill collars during petroleum drilling operations. Constructed from alloy steel grade 4140 or 4340 with heat-treated load-bearing surfaces, it conforms to API 8C specifications for drilling and production hoisting equipment. The square shoulder design ensures secure engagement with tool joints, reducing slippage under high-torque conditions.
The material composition includes chromium, molybdenum, and manganese for enhanced tensile strength and fatigue resistance. Heat treatment achieves a hardness range of 32 to 36 HRC on critical contact surfaces. Typical load ratings are 150 to 450 kips, depending on size and configuration. Surface finish is machined to prevent galling, and internal bores are precision-ground to maintain alignment under cyclic loading.
This equipment is purchased by drilling contractors, well service companies, and offshore rig operators operating in North America, the Middle East, and Southeast Asia. Orders are typically placed for complete sets matching specific pipe diameters. Standard delivery includes lifting pins, safety latches, and lifting eyes. Trade terms are usually FOB Jiangsu port or CIF destination, with lead times of 45 to 60 days after deposit. Buyers must confirm load testing certification for each unit.

Before ordering, verify that each elevator unit has a valid API 8C compliance certificate and load test report issued by an accredited lab. Confirm the material certification (MTR) matches the specified alloy grade and heat treatment. Do not accept units without serial numbers or test documentation, as this violates industry safety standards.
Logistics are typically shipped via container from Jiangsu port. Lead time is 45 to 60 days after deposit. Incoterms are commonly FOB Jiangsu or CIF destination port. Payment is usually 40% advance, 60% against BL copy. Confirm container loading method, as elevators require secure bracing to prevent damage during transit.
Upon arrival, inspect for surface damage, missing hardware, and mismatched serial numbers. Conduct a visual check of jaw wear and latch operation. Request a third-party inspection for load testing if the equipment will be used in offshore or high-risk environments. Retain all documentation for regulatory compliance and insurance purposes.
