From stabilizing legs and counterweights to swivel parts, hydraulic tanks, and complete chassis, Zuidberg develops a wide range of steel components for Hoeflon’s mini cranes. “In the beginning, our focus was on cutting and bending work, but over time, machining and welding were added,” says Sales Engineer Johan Bakker. “Since 2013, we’ve had a factory that houses all disciplines under one roof. This allows us to produce components efficiently and assemble them with precision. Hoeflon only needs to complete the final assembly.”

EARLY INVOLVEMENT

When new developments arise, Hoeflon involves the Zuidberg team early in the process. Johan explains, “We study the model, determine which steel components we can produce, and explore what’s possible within our production process. By sharing our insights and ideas, Hoeflon gains a clear understanding of feasibility not just when production starts, but even before the first concept is drawn.”

FROM WHAT TO HOW

After the initial analysis, Hoeflon creates a design that Zuidberg’s team reviews. “We align all disciplines,” says Manufacturing Engineer Marcel Souman. “For example, do we weld manually or robotically? How do we organize logistics from production to delivery? Our experts in cost, quality, and safety also weigh in. This results in a clear overview of all opportunities and challenges.”

NEW TECHNOLOGY

Sometimes, a small design adjustment saves a significant amount of time, or the desired quality can only be achieved through a new technique. “In such cases, we discuss this openly with Hoeflon. Recently, we integrated ARC|EYE into our process — an advanced laser system that scans and tracks weld seams in real time, enabling our welding robots to work even more precisely. Now that we’ve implemented this technology, we also use it for other projects.”

FIRST TIME RIGHT

Finally, Zuidberg’s team produces a prototype. Sometimes, a test series follows to assess both component quality and process performance. “I always reserve extra time and materials to fine-tune everything,” says Production Planner Michael Kelder. “ ‘First time right’ is our standard. Once we start series production, every detail must be perfect. We fully understand how crucial it is that each mini crane meets all quality requirements.”

52,000 CUSTOM COMPONENTS

Once everything is approved, production begins. “We create a production plan aligned with Hoeflon’s needs,” Johan continues. “In addition, we often supply simpler cut and bent parts or drill holes in specific components — those processes don’t require the same intensive planning. Each year, we deliver around 52,000 different components to a wide range of clients. The fact that we can provide custom work on such a large scale makes us truly unique.”

MANUEL DAUVILLIER
Purchasing Manager at Hoeflon, about working with Zuidberg:

“Zuidberg has been supplying cut and bent parts for our cranes — the C1, C4, C6, C10,and C30 — for many years. When we began developing the C30, a new model with even greater lifting capacity, we decided to involve Zuidberg again — this time not only for standard parts, but also for more complex steel components.

The size of the company, the range of disciplines, and their constructive approach immediately gave us confidence.

For the C30, the standards were high. Zuidberg quickly formed a team of specialists and even invested in special welding wire and ARC|EYE. This demonstrated their flexibility and problem-solving mindset — key reasons why our partnership has grown stronger.

Over the years, Zuidberg has evolved from a reliable supplier into a valuable partner. We especially appreciate their open communication and the dedication of their employees. As a family business, they show true craftsmanship and actively think along with us to improve and optimize our components. That gives us great confidence for the future — together, we can achieve a lot more.”
