Designing

Our firm owns a team of specialists in the field of equipment designing, being specialised in the sector of lifting equipment ( tower crane, bridge crane, jib crane)

We also have RADTP and RADTE authorisations issued by ISCIR pursuant to the technical requirements R1/2010

Our offer includes the following types of designs:
– Assembly/disassembly design;
– Design for location and operation management of the tower cranes on the site;
– Design for the anchorage of the construction equipment;
– Design for the execution of bridge cranes;
– Design for execution of girder crane;
– Design for the execution of jib cranes.

 

Chipping Processing

Machining is producing replacement parts and assemblies for various machinery and equipment.

These are manufactured by:  
-turning
-milling
-planing

 

 

Equipment modernisation

The equipment can be modernized by replacing the old electric systems by modern systems equipped with:
-frequency inverters and programmable automates that allow for smooth start-up and shut down, ensuring increased safety in exploitation and diminished power consumption
-implementation of radiocontrol/telecontrol, which allow for ground operation of the crane, an no need for the presence of the crane operator in the crane cabin, who can work besides the slingers, verifying the binding, the handling and correct pilling of the materials.

Modernisation of auto-lifters

Modernisation of tower cranes

Modernisation of bridge cranes and gantry cranes

Modernisation of bridge cranes and gantry cranes of up to 20 I/O

Modernisation of bridge cranes and gantry cranes of up to 60 I/O

 

 

Repairs
