The task presented to Berco for the CTL sector was to create solutions that satisfy the demands of all vehicle functions. This evolution has been reflected in Berco’s innovative range of CTL solutions, which were originally designed to cover a wide variety of applications but have since advanced into the realm of providing more specific solutions for individual machines. Today, however, this margin has been cut significantly, with CTLs able to travel as fast as 18 km/h. For instance, a CTL from around 2009‐2010 was able to travel at a speed of up to 9 km/h, well behind that of wheeled vehicles such as steer loaders which average between 20‐30 km/h. And this industry, to be sure, is constantly evolving. Berco CTL undercarriage Berco’s vital role in CTL developmentĪs the global market leader in the creation of CTL undercarriages for OEMs, Berco is at the forefront of design and innovation in terms of solutions for both today and the future. ![]() The machine, therefore, must have an undercarriage with small idlers in order to provide as large a base as possible to the vehicle. To achieve this, the front and rear points are situated at the extremes, both when loading the shovel in the front and when the machine is (with the shovel unloaded) doing other types of work with the centre of gravity at the rear. ![]() Being a machine that has its centre of gravity transferred from the rear to the front, a CTL requires great amounts of stability. Case’s CTL 450 Minotaur is a good example of this,” says Grenzi.Ī typical CTL undercarriage high drive has the sprocket elevated because two fixed support points are needed in front and behind. “CDLs are crawler dozers in their own right and are venturing into the world of utility crawlers used in fairly heavy duty areas. These include mini loaders (such as walk-behinds, machines without a cab, crawler pallet trucks etc.), ones with suspended seating to ensure driver comfort and Compact Dozer Loaders (CDL), which on top of its loader function, can also be equipped with a classic front blade. Normally equipped with a rubber track, the CTL has evolved in a variety of directions to satisfy the demands of different markets. Indeed, the market share is still small in Europe, but it too is also growing,” he explains. All of these factors explain CTL’s increase in sales, with 95 percent of these occurring in America. Additionally, it’s easy to transport on a trailer. It’s also more versatile than a dozer and it costs less too. ![]() “A steer loader is already extremely versatile due to its wheels but if you mount a rubber track instead of tyres, you get an even more flexible machine. This sales growth is due to the increased benefits which CTL provides. Today, however, the CTL is the main player with between a 60‐70 percent market share, with the steer loader now on around 30 percent,” confirms Grenzi. “Before the turn of the millennium, the steer loader dominated the market. Ranging in weight from 1t to 6t, the CTL has seen its popularity go through the roof in the last 20 years, thanks in particular to its variety of uses as well as a reduction in price and maintenance costs that existed previously. It can even be used in agriculture to furrow soil or to sow seeds, so it comes as no surprise that interest in this sector has grown significantly in the last three to four years.” The CTL on the market “You can use CTLs with a hydraulic hammer and a shovel, the telescopic handler can lift and sort material, it can be used to till the soil and for deforestation. “These are machines that can do everything,” confirms Francesco Grenzi Head of R&D at Berco. These include powerful lifting, pushing, and digging performance, outstanding traction, low ground disturbance, attachment versatility and added flotation. First manufactured by Takeuchi 1986, the CTL has become an indispensable compact dozer thanks to the multitude of different tasks it can accomplish. Only a few years later in 1962, however, the first Bobcat‐branded skid‐steer loader had already been introduced, and this directly led to another innovation: the Compact Track Loader (CTL). When the brothers Louis and Cyril Keller invented the first front-end loader to help a local farmer remove turkey manure from his barn in Minnesota in 1957, few could have imagined the impact this development would have on the world of heavy machinery. ![]()
