Cable reels

Cable reels

Since the beginning of the use of mobile electrical equipment, the question arose as to how to move moving mechanisms. The cable quickly fell into disrepair: the insulation was abraded, the wires were broken, and as a result, short circuits appeared. Such malfunctions led to equipment damage and personal injury, which is associated with servicing the machines. In order to avoid all this, use cable drums. Due to its design, it was possible to avoid the above-mentioned problems. The cable loosely unwinds and fits into the tray. With the direct movement of the mechanism, the cable is wound on the cable drum without creases and abrasions. Thus, cable drums provide a long and uninterrupted “life”, both for cable and equipment in general.

Slip rings

The use of ring collectors is associated with the need to supply power to those parts of the mechanisms that rotate about their axis. Such current collectors are used not only for power supply. There are special modifications that allow the transmission of low-current low-voltage control signals. All this range of possibilities allows ring collectors to be a universal means of transferring electric current to rotating parts of mechanisms, such as platforms, crane towers, rotating cabs of excavators, reclaimers and other heavy and complex equipment.

Cable trolleys

Cable trolleys

The issue of supplying cables to different distances for the power of the crane trucks excites the designers since they started using the electric drive as a means of lifting and moving loads. The cable had a considerable depth of sag and interfered with the normal operation of the mechanisms. The way out of the situation for some time were the so-called rings for fixing the cable. On the tensioned cable, the rings were fixed, with the cable fixed to them. Such a design had to slide along the steel cable and not allow sagging the cable. But the rings slipped poorly, the cable stretched, threatening to tear. There were regular entanglements. The best offer was the use of roller carts to support the cable.

Shore-to-ship power equipment
This product is ideally suited for providing power connection for lifting equipment and sea vessels, disconnecting electrical circuits, as well as protecting against short circuits and overloads, which provides additional protection for consumers and installations.
According to their design, the columns are divided into 3 types: The main components of the crane electric sub-type columns are in the frame.

Conductor rails

Conductor Rails

At large distances of movement in an enclosed space, it is rational to use a stationary current supply system. For mechanisms that have a certain trajectory of motion, rectilinear or curvilinear, a trolley track is used. A three-pole version of an open busbar trunking system is an analog of the Soviet current supply used. Such systems have proven themselves on the best side, as unpretentious and reliable current leads. Outside the premises, closed busbars are most often used, in a plastic sheath. Such systems can have up to five, seven poles. The same distinguishing feature of such current leads is their compactness.

Current collectors for conductor rails

Current collectors for conductor rails

The trolley current supply system is designed in such a way that the smallest and lightest part of the equipment is worn out. Such an element was the current collector. The current-carrying brushes are made of a copper alloy and, at the same time, with good current conductivity, have the property of being washed out leaving the material of the trolls themselves intact. Along with the universal current collector for trolls of open type in the line of our products there are also special offers.
