Innovation in demolition and recycling attachments
By Steve Ducker20 April 2022
There are few markets in demolition and recycling as diverse as the attachments sector, so it is no surprise that product developments are happening all the time as the technology continues to evolve.
With its current range of demolition and recycling products, Demarec – now part of Kinshofer Group – has been active in the market since its foundation 20 years ago. Managing director Marcel Vening says: “Given the developments in the market, we have been brainstorming about the idea of launching a new product line aimed at the middle segment.”
This has resulted in the Demarec EcoLine. The first product category in this range is the DLP rotary pulveriser. Later this year the first EcoLine static pulveriser will be introduced to the market. “Ecoline initially consists of five models for machines from 9 to 32 t,” says Marcel. “But the range will be expanded further up and down.
The DLP EcoLine is equipped with a standard cylinder technology and a different technical construction, with an exchangeable tooth system specially developed for it. The complete rotator head is the same as with the existing models.
The knives and scraping teeth are also used, for example, in the Demarec Multi-Quick-Processor MQP. Demarec says that its philosophy of fully interchangeable wearing parts has therefore also been applied to the Ecoline. Similarly, Demarec’s DXS scrap shear is also designed for heavy duty tasks, such as demolition and scrap metal processing. Described by manufacturer as the “strongest scrap shear on the market”, the DXS scrap model is available in four sizes for mounting on excavators weighing between 18 and 80 t.
It includes Demarec’s patented DemaPower 2.0 cylinder, which is said to give the model the same performance as “shears one or two sizes up.”
MBI Eagle III Shears released in the UK
Inmalo has announced the release of the MBI Eagle III Shears to the United Kingdom market. They will run alongside the existing Eagle II range. The new shears will out compete the biggest names in the market with new, larger cylinders described as offering 25 to 30% more power than existing shears, as well as redesigned cylinders said to be able to work at 380 bar pressure instead of the industry standard of 350 bar.
On the reliability aspect they have an improved piercing tip that is stronger and covers the end of the jaw to reduce time consuming rebuilding works. Replaceable armoured plates have also been fitted to the jaw, again to reduce downtime for rebuilding the shear.
To improve material quality the jaws are built from single sections of steel which reduces welding and improves strength. The Eagle III range will initially cover machines from 20 to 150 t.
Adapted forklift for demolition
The Pettibone Cary-Lift 204i rough terrain forklift can be equipped with a scrap baler attachment for handling debris and materials in demolition and recycling applications.
The machine is purpose-built to deliver numerous safety and performance benefits over other material handling alternatives. The product features an overhead lift arm design, giving the operator full front visibility when lifting or transporting loads, while the forks are capable of tilting down 90° for specialised lifting tasks.
Manufactured in the USA, the 204i is powered by a 200 hp Cummins QSB6.7 Tier 4 diesel engine with DOC (diesel oxidation catalyst) and SCR (selective catalytic reduction) aftertreatment. The unit includes an engine-driven fan, cooling package and engine block heater as standard equipment.
The machine provides a maximum load capacity of 9,071 kg (20,000 lb) and lift height of 4.88 m (16 ft). Pettibone said the Cary-Lift’s heavy-duty, solid steel frame design allows it to take full loads into sharp turns without sacrificing load capacity or stability. Hydraulic frame sway control and side shift capabilities further stabilised loads by levelling the lifting frame when driving on uneven ground.
The sway cylinder moves 7° both right and left of centre. Dual joysticks provide intuitive controls to efficiently shift gears and control the hydraulics. An optional feature is X-Command, a new Pettibone telematics programme that offers real-time access to machine data.
Consistent power for demolition projects
Caterpillar’s new Performance Series Hammers are described as suited to heavy duty tasks such as demolition. The Cat H190 S and the H215 S models are the largest in the attachment range, which comprises seven other models, and offer 370 to 530 and 300 to 520 hammer blows per minute (bpm) respectively.
Built for high production, the models are said to deliver consistent breaking power and emit less waste from internal heat, which allows more power to be delivered to the tool.
In addition to featuring a buffering material that dampens vibration feedback to the carrier, the hammers can also be configured for joystick or pedal control to suit operator preferences. “With piston and tool matched in diameter and mass, these new hammers offer increased power transmission frequency,” says Cat. “Operators can switch power mode from high frequency/low power to low frequency/ high power, giving the ability to fine tune power to the material being broken.”
The H190 S and H215 S, which were launched in December 2021, were designed for use with Cat’s next gen excavators. While the H190 S is sized for mounting on Cat machines with operating weights of between 43 and 80 t - which includes the Cat 349 through to the 374 excavator models, the larger H215 S can be used with the 374 and 395 machines, weighted at between 65 and 120 t.
The XC5F crusher
The experience of Spanish attachment specialist Xcentric is that clients are demanding crushers for their machinery when recycling on site. Usually, the types of machines they use are skid steers, telehandlers and backhoes. In response to this demand, Xcentric developed its first front crusher model, the XC5F.
The company says that during the development, the best balance was sought between maximum power offered by the excavator and greater input size capacity in the crusher. The result after intensive use of the crusher in all type of conditions, was to make it possible for it to work with flow rates of 90 l/ min and pressures ranging between 16 MPa and 24 MPa.
The material input capacity is 810 x 360 mm (32 x 14 in), allowing practically all the material to be ground in this type of work to be directly admitted by the crusher without having to previously reduce its size.
Thanks to the dynamics of the movement of our mobile jaw, this crusher model supports crushing in two directions, “forward” and “reverse.” The change from “forward” to “reverse” is immediate from the joystick of the excavator, achieving with the combination of these working modes, under the operator’s choice, a great performance in each cycle. The operator can then choose the most suitable mode to grind and switch immediately if necessary.
