Vibration analysis is a key tool in estimating the condition of a roller bearing. The spectral distribution can deliver accurate information on the type and location of the damage. This accessory set-up contains six roller bearings on which different faults can be detected and explained. The slow change in the vibration spectrum provides indications of the remaining life of a bearing and can be used as a criterion for its replacement. The radial load on the bearing can be set within broad limits using the belt drive accessory set (setting of belt tension; fixed load).

The components are clearly but compactly arranged in a manner similar to that used for many domestic air-water heat pumps and all are visible from the front of the unit.
The Water Water Heat Pump consists of a hermetic compressor, an efficient plate heat exchanger condenser and evaporator, a liquid receiver, a thermostatically controlled expansion valve.
The operating cycle is as follows:
Slightly superheated Refrigerant vapour enters the compressor from the evaporator and Water Water Heat Pump pressure is increased. Heat is given up to the cooling water and the refrigerant condenses to a liquid before passing to the liquid receiver and then the expansion valve. This brings about a rise in temperature and the hot vapour enters the water cooled plate condenser.

The unit represents a planar central force system in which multiple forces act on a single point of application. The compression jib and the tension tie make up the jib crane, which is attached by adjustable clamping elements to a retaining bar. It consists of a bar of adjustable length (compression jib) and a chain (tension tie), which is adjustable, and both incorporate a spring balance to measure the bar forces in them.
The Unit for studying Forces in a Jib Crane is designed to study the tensile and compressive forces in a planar central force system based on the example of a jib crane.
Based on the example of a jib crane, forces are determined experimentally, theoretically and graphically: resultant cable force, tensile force and compressive force. The magnitudes and directions of the forces are graphically determined with a force parallelogram.
A weight holder and a set of weights apply loads to the jib crane through the junction of the compression jib and the tension tie.
