CDZH Hydraulic Elevator
CDZH Hydraulic Elevator – API 8C-certified heavy-duty lifting tool for 2⅜"–14" drill pipes, collars, and casings, with 50–500-ton capacity. Engineered for harsh onshore/offshore and Arctic rigs, its hydraulic system delivers 0.5 m/s lift speed (40% faster than mechanical elevators) and smart pressure control (10–35 MPa) to eliminate pipe slippage. Built with H2S-resistant alloy steel and modular jaws, it withstands corrosive muds and extreme temperatures (-40°C to 150°C). Remote operation enhances safety in hazardous zones, while self-lubricating parts reduce maintenance.
Product Details
Product Overview: CDZH Side-Opening Hydraulic Elevator
API Spec 8C-Certified | Dual-Valve Hydraulic System | Multi-Pipe Adaptability
The CDZH Hydraulic Elevator is a heavy-duty, side-opening elevator engineered for efficient handling of tapered drill pipes, collars, casing, and tubing in demanding oilfield operations. Featuring a dual-valve hydraulic control system and modular bushing design, it enables rapid switching between pipe types (2⅜"–9¾") while ensuring operational safety and compliance with API Spec 8C standards. Ideal for onshore, offshore, and Arctic drilling environments, it reduces manual labor by 50% through remote-controlled operation and enhances rig efficiency with 350–500 short-ton load capacities.
Key Technical Specifications
