Control cabinets for challenging conditions
Products manufactured by Rambooms are used for the demanding need of mines and quarries.
Rambooms has selected Makron Automation as its supplier of control cabinets for mining environments. The Lahti-based Rambooms manufactures breaker booms used by the mining and earthworks industries for crushing stone material. Because Rambooms products must be resistant to oil and dust in addition to withstanding temperatures that range from subzero Siberian conditions to the scorching heat of South Africa, the control cabinets are designed also for robustness.
Collaboration between the companies kicked off more than a year ago with product development, when Rambooms ordered the design and manufacture of prototypes from Makron. Even though the breaker-boom manufacturer requested offers also from other suppliers on the basis of these prototypes, in the end the seamless product-development collaboration swayed the decision in favor of Makron. With 10–20 control cabinets expected to be delivered each month, the deal entails a large-scale partnership.
Makron has built a separate unit for the manufacture of cabinets for Rambooms, consisting of four workstations, plus component storage to facilitate speedy production. The cabinets can be delivered to a tight schedule, as required by the client. To expedite the process, the company always has eight semi-finished cabinets ready for completion. The contract involves 40 cabinet types, designed to form a series in which all products have identical dimensions and share various components in common. The remaining components are added in response to specific power and voltage requirements.
The semi-finished cabinets can be completed rapidly, with turnaround as quick as a single day. Once a cabinet is assembled, a Makron technician loads and tests the necessary software for it. After this, the technician installs the cabinet on the boom on the client’s premises and checks the boom operations. The first delivery was completed in August, with much more to come.
