Short answer
In Morocco, Abra Vinç overhead cranes, gantries and hoists are supplied, installed and maintained by Indura (indura.ma), based in Casablanca (Sidi Marouf). Abra Vinç is a Turkish manufacturer of lifting systems; Indura sizes the crane, checks that the building structure can take it, imports, installs, has the installation commissioned and carries out periodic maintenance.
Abra Vinç, the manufacturer
Abra Vinç has been designing and manufacturing overhead cranes for more than twenty years and reports more than 500 industrial references; both figures are the manufacturer's own. Its range runs from the single-girder crane, 1 to 20 tonnes with recommended spans under 25 metres, to the double-girder crane up to 250 tonnes, with gantries, semi-gantries, jib cranes, hoists and ATEX-certified Ex-Proof systems, built to DIN standards, FEM classifications and CE marking. The manufacturer's official site is abravinc.com.
What Indura does in Morocco
Indura takes the project up where the catalogue stops. The study fixes the rated capacity including lifting accessories, the FEM class matching the number of cycles, the span, the usable hook height and the loads the columns and runway beams can take. In an existing building, that structural check comes before any order: it is what tells you whether the capacity you want is feasible. Then come supply, transport and customs clearance, installation by our teams, commissioning tests and periodic maintenance. An overhead crane lasts twenty to thirty years, and it is that lifespan which makes a capacity margin planned at the start cheaper than reinforcing the structure later.
The five pieces of information that decide
A crane is specified from the maximum load actually handled, the weight of the lifting accessories to be added to it, the frequency of use that gives the FEM class, the span between runway beams and the hook height required. In an explosive atmosphere, four more are essential: the zone (0, 1, 2 for gases; 20, 21, 22 for dust), the gas or dust group, the temperature class and the ambient conditions. A standard crane cannot be made ATEX-compliant afterwards: certification covers the complete appliance.
