Break(er) Time!
Published: 31/5, 2021
It’s been a tough year for everyone, particularly demolition equipment manufacturers located in areas of the world severely hard-hit by the coronavirus. Still, many companies have pushed forward with new and upgraded hydraulic breakers and other attachments designed to help contractors continue their quest for jobsite efficiency, operational reliability, and low ownership costs. Whether the job involves infrastructure, buildings, or other types of facilities, these breakers are ready to get to work.
Indeco Spotlights Its Latest Innovations
The HP 100 FS, the smallest hammer in the Indeco range, made its US debut at Conexpo last year as the HP 150 FS. The American market is increasingly on the lookout for mini-excavators and other compact carriers from 0.7t upwards, which can operate in restricted working areas. Capable of top performance even with reduced hydraulic flow and weighing under 132 lb (60kg), the little giant of the Indeco hammer range streamlines job times and ensures excellent productivity through an impact energy per blow which is unparalleled among hammers in the same class.
Two lightweights in the Indeco small hammer range—HP 400 FS and HP 550 FS—offer improved performance with new powerful features, including increased energy class, blows per minute, and tool diameter. While both models’ hammer size and design are unchanged, Indeco’s upgrades decidedly improve the perfect match with excavators, providing maximum hydraulic efficiency for the finest performance in its category.
A totally new product that extends the already broad range of large Indeco hammers is the HP 6000 FS, which takes up a position midway between the HP 5000 and HP 7000.With this product Indeco aims to provide an answer to a specific trend in the excavator world, which is seeing 30t carriers increasingly replaced with slightly larger models weighing 35-36t. The new HP 6000 hammer is an ideal fit for excavators in the 35-45t range, especially given its excellent power-to-weight ratio. The new model is also a champion of productivity and reliability, partly due to the HARDOX® inserts in the lower part of the casing, which enable it to withstand even the toughest jobs.
Finally, Indeco has introduced a new automatic greasing system developed by Bekalube’s technical staff. A series of key systems are designed to keep hammers in perfect working order by using the right amount of lubricant and cutting out the down times needed for manual greasing. The new kits are divided into two categories – on-board systems fitted directly onto the hammer, and units mounted onto the excavator. In both cases, these systems are connected to the hammer through a single greasing point.

Doosan Launches New HB-series Hydraulic Breakers
Doosan Infracore has launched the new HB-series hydraulic breaker range. The new five-model range provides a novel concept with high performance and a simplified design, specifically optimized and fully certified for Doosan excavators with carrier weights from 1.2t to 15t, as well as attachment carriers from other manufacturers. As a result, Doosan HB breakers offer the highest possible productivity, whether the operator is demolishing concrete or breaking rocks.
The breakers’ service life is extended through adoption of an advanced heat treatment process and quality proven materials for key components including the cylinder and piston. The energy of the piston stroke is accumulated by charged nitrogen gas and an inward valve system with a simple structure and fewer inner parts.
A urethane damper prevents vibration that might damage the carrier and improves operator comfort. The front head supports the breaker and assemblies with bushing, which buffers the shock from the tool. The low noise housing is ideal for working in urban zones, where noise levels must be controlled, or where local regulation may require silenced breakers.
Ideally suited for demolition work, the Doosan breaker range is also intended for general construction, rental, quarrying and mining applications. Backed by an industry-leading two-year warranty, the breakers are available at cost-effective prices, providing customer benefits in terms of total cost of ownership. And as with all Doosan machines and attachments, the new breakers are covered by the Doosan dealer service network and product specialists, providing fully comprehensive “one-stop service” support.
Idromeccanica’s Big Breakers Can Handle Big Jobs
Around the world, demand for big breakers has increased incredibly. Idromeccanica has promptly satisfied the latest trends by offering the improved IMI 170M, IMI 240M, and IMI 320T which are now the company’s best-selling models.
Specifically, the IMI 170M features a 5.3-in (135mm) tool and weighs 3,968 lb (1,800kg) fitting machines from 21t to 30t. The breaker releases 3,319 lbf (4,500 J) of energy, and assures 400-800 blows per minute. It suits the most common excavator classes, and is suitable for any job. The IMI 240M breaker is equipped with a 5.9-in (150mm) tool bit matching machines from 26t to 35t, providing a power of 4,794 lbf (6,500 J) with 370-800 strokes per minute.
Last but not least, Idromeccanica offers the powerful IMI 320T, featuring a heavy-duty casing with a 6.1-in (155mm) tool. The IMI 320T weighs 7,055 lb (3,200kg) and suits machines from 35t to 50t. As with other IMI breakers, the 320T matches any machine in its class.
All IMI breakers feature an attractive design, and are supplied with air and grease holes—features that are many other brands offer only as options. The air hole allows to use the hammer for underwater works while the grease hole allows to simply bolt on the automatic lubrication device making greasing very easy and comfortable.
All Idromeccanica are made entirely with pride in Italy. The company pays close attention to quality, performance and design and continually monitors customer needs, making R&D the company’s everyday goal. Look for bigger models to join the IMI product range soon.
JCB’s Contractor Range of Hydraulic Breakers
JCB Attachments offers its Contractor range of hydraulic breakers designed to work with .5t to 60t excavators, backhoe loaders, and compact machinery from JCB, as energy, and well as other brands of excavators and breaker tool carriers. The range now includes 14 models, from the compact HM012T that tips the scales at just 264 lb (120kg) to suit mini and micro excavators, to the 3.8t HM380T, which has been designed to work with excavators in the 40-60t category.
HM033T and above Contractor breakers have accumulators to protect the carrier machine from hydraulic pressure spikes, reducing possible wear and tear on the hydraulic system. HM080T and above Contractor breakers are equipped with refillable auto-greasing system, and an auto-stop feature that reduces blank firing, protecting the breaker from unnecessary wear and damage.
Internal control valves deliver higher efficiency and are less vulnerable than competitor models that rely on external valves, while two-speed control valves allow the operator to customize tool speed and stroke length, dependent on the material that is being broken. This increases productivity and reduces the risk of damage to the breaker and the carrier.
Hammers for use with equipment above an 8t operating weight come as standard with a refillable auto greasing system, ensuring the breaker always receives the correct amount of lubrication throughout the working day. This cuts downtime and boosts productivity for the customer.
Twin oval tool retaining pins are included on heavier models, delivering double the life of a standard pin, as they can be rotated to wear on both sides. Smaller breakers are equipped with a single tool retainer.
Contractor breakers use a single scaled design with the same maintenance requirements for each model. This ensures that dealer and customer service staff, particularly in a rental operation, can easily work on all hammers in the range. All models undergo final assembly in the UK to the highest quality levels, and come backed by a three-year manufacturer warranty.
