The double-line support apparatus include a first anchor block, a second anchor block and a double-lifeline system.
A tensioning and anchoring system may include one or more tensioners integrally connected to an anchor block.
The anchor block is thus protected from the well bore by the drag block, and the biasing arrangement provides for automatic un-setting of the anchor block when torque is removed from the mandrel.
The double-lifeline system includes a plurality of lifelines configured to operatively connect to the first anchor block and the second anchor block.
The bearing assembly has an anchor block, an anchor bearing having an inner race attached to the upper end of the anchor block, and an outer race fixed within an upper end of a column.
The guide ducts have a transversal distribution in the direction of the anchoring block whereby said distribution is aligned with the distribution of the openings.
The cable wires are distributed into seven-wire units (18) in a portion of the cable adjacent to an anchor block (13), and these seven-wire units are individually anchored on the anchor block.
The biasing arrangement biases the anchor block away from the well bore and the drag block toward the well bore.
The annular seal (26) is inserted from the anchor block end (1) of the anchorage.
The facing blocks (32), as well as the anchor blocks (34), have hollow, vertical throughbores (70).
The anchor pad is attached to the back of the handheld device and the terminal end of the connector is attached to the anchor pad by means of connection.
Said tape-shaped material (5) is pretensioned by means of the tensioning anchor (20).
The present invention is directed towards a lifting anchor for embedment in a concrete member.
Said extension element is effectively connected to the tape-shaped material (5) and the tensioning anchor (20).
The drag block contacts the well bore at least when the anchor block is out of contact with the well bore.
The cover block fits vertically onto the anchor block and can be moved forwardly into a locking position which prevents vertical, forward, or lateral movement of the cover block.
The anchor block can be secured to the main housing of the drop terminal by a mechanical interlock.
The outer race of a guide bearing is fixed within the lower end of the anchor block.
The anchor block has a second hole therein capable of fixedly engaging the shaft of the roof anchor once the anchor block is thus drawn up to the underside surface of the roof support structure.
Each tendon of the cable is held in a respective channel of the anchor block with a blocking member (19).
The anchor block is secured to the lengthwise generally horizontal support surface (17b).
The first anchor block is configured to be disposed at a first distal end of a tunnel section of a boarding bridge.
The anchorage members are attached to the base or the seat or wheel chair support by means of an adjustable tightening mechanism, thus operating to draw the anchorage block towards the base.
A cable passes through the torque tube from the proximal end of the lead through the anchor block to the distal end of the lead.
The ring element may be attached to the device via a receiver, a connector, a terminal end and an anchor pad.
