The Quality Control specialist
Slideshow: interview with Biagio Longo, responsible for quality control of materials
Biagio Longo is the specialist at Simex responsible for quality control of materials and some of the most critical components. He is assigned to checking that they meet the stringent requirements established by the Technical Dept. before and after they have gone through the production cycle. During this painstaking control process, he devotes utmost attention to the materials used to manufacture parts made to bear heavy stresses, all selected from the family of high-strength steels such as Hardox and Weldox. Sample tests are carried out in the laboratory using a durometer and other instruments that evaluate dimensional ratios by a tenth of a millimeter in order to control the precision of parts that require very low tolerances to assure the productivity and reliability of the products. In the outside areas sample tests are performed to evaluate parts that are heat-treated to meet project specifications.
Biagio's job, like that of many at Simex, makes an important contribution to rendering our equipment productive and durable.
Eleven T 600 wheel excvators on the job in Turkey
Slideshow: T 600 at work in Turkey
Topaz, a company of Cukurova Holding, one of Turkey's most important groups, is active in the telecommunications industry. The company constructs and manages a fibre optic network that extends throughout the country, linking major cities. Topaz also provides for the design, application for permits, as well as construction of the network. The company recently completed a job to lay the new backbone running between the cities of Adana and Gaziantep, a project that involved the excavation of a trench 8 cm wide and 60 cm deep for a distance of 260 km.
Along the main thoroughfares and in urban settings, excavation was performed using seven Simex T 600 wheel excavators, a fleet soon to be added by an additional four to take on another important infrastructure project to lay a cable TV network for a total 1000 km.
With a maximum excavation depth of 60 cm, the T 600 boasts an exceptional work capacity. It is ideal for cutting and digging small fixed-section trenches on hard, compact surfaces, such as asphalt, rock and concrete. The equipment also guarantees excellent visibility and safety, with excavation advancing with the wheel fully protected at any given depth. Like other Simex wheel excavators, this attachment's winning features are the hydraulic piston motors with direct wheel drive, a solution that ensures high output and low overheating. For these reasons, Simex technology has been recognized by Topaz as the most productive and reliable technology for the important works they have been assigned.
Simex PL-SG to scarify under guardrails
Milling and finishing requirements have changed in recent years and are still evolving every day. Our work to design and construct machinery has focused on these new developments and our research has led to a highly effective solution.
We became aware of the need for a special type of planer, a versatile attachment that could mill directly under guardrails, or when leaned flat against the guardrail, to mill exactly on the same plane.
The planer would have a dual application: the first requirement was to meet specifications to excavate a trench or gutter on the section of asphalt located underneath the guardrail. In the past, this job could not be performed by large cold planers or traditional self-levelling planers.
A solution also had to take into account the new type of guardrail, which in future will have a height of 60 cm instead of 45 cm, an application where the Simex planer would be positioned not against the structure, but underneath so as to remove the step left by larger machines.
Specifically designed to meet these requirements, the new PL-SG is built with a frame and shifting plate and designed in a special shape to allow scarification under the guardrail. The PL-SG features one side panel with lateral slide, ledge on the upper part of the wall side to enable the planer to rest against the guardrail, depth adjustment and hydraulic translation. It can also be supplied with conveyor belt to remove the milled material so that the trench it is left clean.
Once again, Simex has provided a response to market requirements by designing a targeted solution that assures effective results.
