They are used in moderate and cold climatic regions.

Elevators VM.ETAD (ВМ.ЭТАД)

VM.ETAD (ВМ.ЭТАД) casing automatic dual-link elevators, 50 tons lifting capacity, are designed to latch by the coupling and hold suspended flow strings having 73 mm nominal diameter per GOST 633-80. They are used to support hoisting operations as well as oil wells servicing operations. They are operated in moderate and cold climatic regions per GOST 16350-70. Location category is I per GOST 15150-69.

Elevator’s design provides automatic locking of latching mechanism as tubing is inserted into elevator’s opening. The latching mechanism that closes bracket eyes eliminates the chances that they would open spontaneously. Handles are provided on elevator’s body and latching mechanism to allow ease of elevator’s handling as it is operated.
