Abstract
An apparatus for introducing and/or positioning a device in a chamber of a heat exchanger includes an assembly yoke with ends and a middle. The yoke may manually be introduced into the chamber of the heat exchanger with a pole. At least three remotely-actuatable clamping fingers are disposed on the assembly yoke. The clamping fingers are designed such that they may be locked or braced in tubes of the heat exchanger. For this purpose, respective locking devices that are remotely controllable may be used. A lifting cylinder holds one of the clamping fingers at least approximately at the middle of the yoke. Remotely-actuatable clamping devices each hold at least one of the clamping fingers on a respective one of the ends of the yoke. Toothed belts each have an end connected to a respective one of the clamping fingers positioned on the ends of the yoke. Two synchronously controllable elevators each have a toothed belt drive in engagement with a respective one of the toothed belts. Support elements and releasable connectors for the device to be introduced and/or positioned are disposed on the synchronously controllable elevators.
