The present invention relates to an elevator and a method for measuring the load in an elevator, in which the elevator car is suspended on hoisting ropes with at least one upward-directed diverting pulley or diverting pulley pair, from which the elevator ropes go upwards on both sides, and at least one downward-directed diverting pulley or diverting pulley pair, from which the elevator ropes go downwards on both sides. In the elevator at least one upward-directed diverting pulley or diverting pulley pair and at least one downward-directed diverting pulley or diverting pulley pair is fixed to the elevator car with a shared supporting structure. In the method the tension information is measured from a supporting structure and a load-weighing signal is formed using the tension information obtained.

Elevator

A device for moving a pig through a conduit, such as a pipeline, is proposed, comprising at least one pulling element with at least one sealing means. The sealing means comprises a supporting structure with variable circumference with at least one sealing element disposed on the circumference of the supporting structure. In a preferred embodiment, the supporting structure comprises supporting arms disposed substantially radially and being pivotable about axes, each perpendicular to the longitudinal central axis of the pulling element, and is mounted to the pulling element via the supporting structure and a central sleeve which can be fixed to the pulling element.

Device for moving a pig through a conduit, such as a pipeline, and sealing means for a device of this type

A device ( ) for passing through pipes in the form of a pig ( ) moving through the pipe and guided on the inner wall thereof has at least one pig body ( ) and support elements ( ) on the outer periphery thereof for guidance within the pipe as well as drive elements ( ) in the form of collars for transport in the pipe. The device is distinguished by improved entrance into the pipe conduit in that at least one of the collars ( ) can be radially expanded.

Device for passing through pipes

In order to facilitate introduction of an inspection pig through an introductory conduit having a smaller diameter and into a pipeline of large diameter and transporting a fluid, in particular gas or oil, the invention proposes a device for inspection of pipes having sensors disposed about an outer periphery thereof having radially expandable inspection units (,), wherein, in particular, a front and a rear inspection unit (,) having sensors (,&prime;) displaced with respect to each other in a peripheral sense can be moved axially towards each other.
