We produce overhead single-girder overrunning cranes
These are more accurate and energy-efficient analogues of heavy double-girder cranes with load-carrying capacity of up to 32 t.
Overrunning overhead-travelling cranes are installed as auxiliary cranes in one span with overhead cranes of large load-carrying capacity and dimensions. With this “neighbourhood”, we necessarily produce and mount optical or mechanical anti- collision system.
A single-girder overrunning crane assembly is a metal structure with an individual travelling mechanism mounted over the above-ground crane rail (rail or square). The hoist is to lift and lower as well as move the loads along the metal structure of the crane.
The main (longitudinal) girder of the crane is (preferably) produced welded, of box-section, but it is reasonable to use the long metal profile for the most rational use of materials at low load-carrying capacities, operation modes and spans.
The end girders (end trolleys) are made of sheet steel, using modern gear motors
(individual drive for each wheel) and housed bearings of leading manufacturers.
The wheels of our overrunning overhead-travelling cranes pass series of software tests to detect possible hidden defects after the heat treatment.
The lifting hoists structurally ensuring the operation of the crane for full potential are installed on the overrunning overhead-travelling cranes. The hoists are selected at the crane design stage, taking into account a set of characteristics such as drive type, construction height, operating mode, etc.
The dynamics of acceleration and the nominal speeds of all the mechanisms are selected, depending on the process, under which a single-girder crane is produced (from mounting energy-efficient cranes to highly manoeuvrable high-speed cranes).
The speed and dynamic parameters are adjusted with frequency converters, the selection of transmission components (gear ratio, multi-speed electric motors) is more economical option.
The mechanism control system is used as a pendant-type panel (optional – radio control), if necessary, a single-girder overrunning crane is equipped with a cabin and connecting passage.
When installing the cranes in the existing workshop, the power is supplied to the crane with trolley, flexible cable, bus duct, etc. used in the production.
