DDZH Hydraulic Elevator

Brief Introduction of DDZH Hydraulic Elevator

Type DDZH hydraulically elevators are the rig tool used in petroleum and gas drilling. During making a trip, Type DDZH hydraulically elevators can hang the tapered Drill pipe, drill collar, casing and tubing through exchanging the bushings conveniently, safely and reliably and favors extending the service life of main body of elevators. The products shall be designed and manufactured according to the requirements in API Spec 8C Specification for Drilling and Production Hoisting Equipment and uses the hydraulic control system, which makes the operation more convenient, effectively reduces the workers’ labor intensity and improves the work efficiency; it can also realize remote control and make the use safer and more reliable.
