DDZH Hydraulic Elevator
DDZH Hydraulic Elevator – API 8C-certified lifting system for 2⅜"–14" pipes with 50–500-ton capacity. Engineered for harsh onshore/offshore rigs, its dual-piston hydraulics enable 0.5 m/s lift speed (40% faster than mechanical elevators), while smart pressure control (10–35 MPa) prevents pipe slippage. Built with H2S-resistant alloy and modular jaws, it withstands corrosive muds, -40°C to 150°C extremes, and reduces maintenance via self-lubricating parts. Remote operation enhances safety in hazardous zones, backed by a 10-year warranty. Ideal for shale, deepwater, and Arctic drilling.
Product Details
Product Overview
The DDZH Hydraulic Elevator is an API Spec 8C-compliant center latch elevator designed for seamless handling of drill pipes, collars, casing, and tubing across diverse oilfield operations. By integrating a modular bushing system, it adapts to pipe sizes ranging from 2⅜" to 6¾", ensuring versatility in drilling, tripping, and well intervention tasks. Its hydraulic control system enables remote operation, significantly reducing manual labor, enhancing safety, and boosting rig efficiency by 30%.
