PIPE FLANGE LIFTING APPARATUS

摘要

The invention is directed to a flange lifting apparatus that is configured to have an upper portion that can be attached to a crane or hoist, and a lower portion that can be attached to a flange using flange attachment arms. The lifting apparatus has a support body comprising with first and second ends and an elongate opening in the support body. A movable support member has an upper portion with opening accommodating a threaded rod, and a lower portion attached to a rotatable cam that is positioned within and capable of traveling within the elongate opening of the support body. Rotation of the rod causes movement of the support member which shifts the center of gravity and causes the flange to tilt.

主权项

1. A flange lifting apparatus comprising:
(a) a support body comprising first and second ends and guide structure extending at least partially between the first and second ends of the support body; and (b) a movable support member operatively connected with the support body by a linear drive mechanism, the linear drive mechanism oriented to move the movable support member in an axial direction of the linear drive mechanism and along the guide structure of the support body, wherein a first portion of the movable support member is configured for attachment to a hoist attachment member, and a second portion of the movable support member includes a guide element that is positioned so as to be capable of traveling along the guide structure of the support body, wherein the apparatus is configured so that controlled drive of the linear drive mechanism can selectively position the movable support member between the first and second ends; wherein, a portion of the support body is configured for attachment to a flange.
