BREAKING GOOD

Published 21/4 at 14:40

Whether there is a need break up some concrete or reduce some boulders, there’s a hydraulic hammer attachment to fit every carrier and budget.

Along with packing a powerful punch many times a minute, they’re also filled with features to enhance efficiency, minimise maintenance and optimise operations. Here we take a look at the latest developments in the breaker industry.

 

Rammer to hit smarter with new releases 

The Rammer ‘Excellence Line’ continues the company’s 40 year tradition of delivering innovative hammers designed to improve profitability, safety and performance. Officially launched at Conexpo/Conagg, the Excellence Line comprises of state of the art hydraulic hammers that are ready for all breaking requirements, with the largest member being the 9033E for carriers in the 65t to 120t range. The Excellence Line has been designed to make it easier to adjust idle blow protection (IBP) in the field, decreasing both operating and maintenance costs. IBP ensures that the hammer cannot be operated until pressure is placed on the tool, also protecting the tool from failure and tie rod stress, reduces oil overheating and protects against premature failures. In addition, all large Rammer hammers have another ‘easy in the field’ adjustable feature,  ‘Stroke Selector’, which allows the operator to optimise hammer operation according to material and application.

Other Excellence Line features include separate greasing channels from the valve body to the upper and lower tool bushing to increase tool/tool bushing lifetime; new, robust plastic wear resistant plates for optimum hammer protection and noise reduction; and easy to use pins to expedite field replacement of the lower tool bushing. However, perhaps the biggest development within the Excellence Line is Rammer’s purpose developed RD3 remote monitoring device, which is a standard feature on all Excellence Line models (RD3 is also available as an option for Rammer ‘Performance Line’ hammers and as retrofit-kit for older Rammer hammers). Using the latest GPS and Telematics technology, RD3 uses the Rammer ‘MyFleet’ Telematics service to track and monitor fleet equipment usage via Google maps. It also comes with a new hammer feature, the ‘hour meter’, which is linked to the unit’s serial number to measure the exact number of hours it has worked. The system further enables owners and managers of fleets to know exactly where their equipment is and how it is being used.

Epiroc’s ‘HATCON’: Hydraulic Attachment Tools Connectivity

Also entering the remote monitoring arena is Epiroc, whose HATCON device is designed for breakers and drum cutters that keeps track of location and operating hours to improve efficiency and safety. The cloud based ‘My Epiroc’ platform gives user notifications about service, creates task lists and provides an overview of the entire fleet. All data is presented in a straightforward way to simplify both everyday duties and long term decisions. HATCON is available factory mounted or as a retrofit kit for Epiroc premium range breakers and drum cutters. Once connected, the system monitors every individual tool and keeps customers updated via My Epiroc. Notifications about service and wear part alerts are just a few of the features that will help increase efficiency. 

 

Komatsu and Montabert team up for a new breaker line

To meet North American customer demand for rock breakers, Komatsu is launching a full range of hydraulic breakers specifically for that market. Manufactured by Montabert, these hydraulic breakers are designed and tested to fit Komatsu excavators from the PCMR30-5 up to the PC800LC-8, without modification.  The product line is among the first product rollouts since Komatsu acquired Montabert earlier this year. The new breaker range will offer the French company’s longstanding tradition of exacting quality, performance and durability in a Komatsu themed package.  The breakers’ high percussion efficiency and unique variable energy technology provide high production in multiple applications. To protect customer investment in the equipment, they feature an anti-blank firing system and automatic greasing.

Backing up product quality is an enhanced service and support network for North American customers, including a new 4,645m2 distribution and customer care centre in Nashville Ill., and breaker remanufacturing facility in Chattanooga, Tenn. Montabert is also planning to open a new remanufacturing facility in Elko, Nev.

 

Red Line membrane type breakers from Green Attachments

The ‘Red Line’ hydraulically operated membrane type breakers from Green Attachments have been designed for mining, demolition, tunnel construction, underwater applications and boulder breaking. Movement is achieved by the hydraulic oil pressure on the piston head and accelerated by the oil and gas load of the accumulator on the top of the piston. This accumulator maintains a constant pressure at the top of the piston, with gas being added only during service. The membrane type Red line breakers are fully hydraulically operated which provides reliable operation. They can operate in all positions due to a long and light piston and a large number of seals. Other features include constant blow energy, low wear, and good hydraulic shock absorption thanks to a unique buffer system which keeps the oil’s thermal heat low for energy savings, while side rods are covered with polyurethane. The hydraulic rock breaker range consists of 19 models for 0.75t to 100t excavators.  

Also from the company is its gas assisted economy ‘Piikki’ hydraulic breakers for customers who have only an occasional need for a breaker. This range is ideal for demolition and excavation assistance, frozen ground breaking etc. Piikki breakers accept higher back pressure and generally larger scale of hydraulic circumstances than fully hydraulically operated ones. Composed of relatively few parts, they also keep operational costs low.  Piikki breakers offer many of the same features as the larger Red Line models, including a system of side, top, and bottom buffers that provide special impact and vibration absorbing properties. Tool and piston diameters are matched for maximum energy transfer.

 

News from Indeco

The smallest hammer in the Indeco range, the HP 100 FS, is being introduced to the US market as the HP 150 FS due to customer demand for equipment or mini-excavators from .75t upwards for working in restricted work areas. Capable of ‘top’ performance even with reduced hydraulic flow, they provide excellent productivity through a high impact energy per blow. Two lightweight members of the Indeco small hammer range - HP 550 FS and HP 400 FS – have been updated to now deliver improved performance with new powerful features. Both have higher energy classes, higher tool diameters and deliver more blows per minute. This upgrading has not changed the hammer size and design of either model, being ideal for 2.5t excavators for the HP 550 FS and 3.5t-6.5t for the HP 400 FS respectively. Finally, Indeco’s new HP 6000 FS takes up a position midway between the HP 5000 and the HP 7000 as a response to a specific trend in the excavator world, as 30t carriers are increasingly being replaced with slightly larger models weighing up to 36t. The new hammer is designed for excavators in the 35t to 45t range, with what is said to be an excellent power to weight ratio

 

Prodem’s family of workhorse breakers

The Prodem PRB series is a comprehensive range specially designed to be cost effective without compromising power or durability. From the small but dynamic PRB008 right through to the mighty PRB1000, they are all workhorses.  A unique valve design and high pressure accumulator in the PRB170 and higher models work to eliminate pressure fluctuations and increase impact power, all the while minimising damage on the excavator pump. The hydraulic hammers also have a specially hardened and heat treated piston that gives long piston strokes which minimises recoil and eliminates mechanical springs. All models in the PRB series features an optimal damping system made of high quality elastomer, which minimises impact induced recoil shock, vibration and noise.

Prodem hammers from the PRB150 upwards feature anti-blank firing to significantly reduce blank blow induced failures and downtime, therefore increasing productivity. The models’ dual speed control adjusts the blow frequency of the hammer to the density of material to maximise productivity: low power/high speed for concrete breaking, soft rock and reducing boulders; high power/low speed for quarrying and trenching. All models feature a hardened rock claw that resists wear and abrasion, with a through bolt which reduces internal torsion stress and increases fastener life. They also have an extremely durable welded full box enclosure with no rigid side bolts to protect components and reduce noise. All come with two tools optimised with high grade steel and heat-treated to maximise durability and efficiency. The hammers are also designed to be easy to maintain as there are fewer moving components and feature a centralised lubricating system, with the option of installing an auto greasing kit.

Hammer builds a breaker for every need

Thanks to more than 40 years of experience, Hammer offers customers a wide range of quality breakers backed by high levels of service. Hammer’s eight model SB line is designed for excavators in the .5t to 11t range, while the FX Line’s 14 models are ideal for excavators in the10t to 200t range. 

Hammer SB breakers can tolerate 25bar back pressure and are designed for easy plug in installation on all types of excavator. Along with high power, FX line breakers have a special hole in the front of the case for connecting an air hose for underwater demolition work. All Hammer breakers feature a closed casing design integrated with upper and lower shock absorbers made of polyurethane, which extends the service life of the main components whist also keeping noise and vibration to a minimum. Hydraulic connections are located deep inside the casing and are protected by an elastic rubber cover, making it possible to safely work in narrow locations. A specially developed lip seal helps prevent the loss of gas losses from the nitrogen chamber, providing longer periods of full power, reducing nitrogen refilling intervals. An oil cushion on the top of the piston, controlled by a regenerative internal circuit, preserves the breaker from blank firings, even if the tool is not in contact with the ground. Finally, the bottom of the piston has a rounded shape that ensures regular contact with the top of the tool which also helps piston damage and component wear.

Two new breakers from Promove

Promove’s new 600kg XP600 and 200kg XP200 complete the company’s XP series of high performance hydraulic breakers. The XP series boasts energy recovery and anti-blank firing systems, a power/ frequency automatic regulation system, and innovative smart valve with a ‘plug and play’ feature that allows users to install the breaker without having to adjust any settings on the excavator. In addition to significant time/cost savings, this eliminates future problems such as premature breakages due to extra flow. This system also allows the breaker to be moved to various machines, making it easier to rent out equipment.

For use with a mini excavator, Promove’s five model light range, which weigh 60kg to 430kg, have been designed to provide a combination of strength and performance, with the 60kg model being ideal for use in even the smallest demolitions site. The larger XP 101 and XP 150 are designed specifically for jobs that require greater delicacy and collateral damage control, offering versatility thanks to their constitutive technology. Shock protection absorbers, mounted above and below the hammer body, avoid vibrations and damage to the excavator arm. The nitrogen valve is easily accessible for faster and more efficient gas control or for refill operations, whilst a low pressure chamber improves the energy at each blow and, together with the increased diameter impact mass, produces a more powerful blow. 

 

Idromeccanica returns to Conexpo/Conagg

After a 20 year absence, Idromeccanica Italiana, once again took its place on the international marketing stage with an impressive display at Conexpo/Conagg which included the IMI 88HP, equipped for skidsteer loaders, and the versatile IMI 121M for machines in the 15t to 24t range. ‘Breakers and beyond’ was the theme for the company serving as a reminder that Idromeccanica manufactures more than a full range of breakers to suit any machine from 1t to 50t. The company also makes other attachments for demolition, mining, recycling and road works. 

During the exhibition, Idromeccanica’s staff identified different trends and needs in the US market regarding hydraulic hammers. The most requested among these are for machines from 40t to 50t and for machines from 4t to 10t. Idromeccanica hopes that the expectations before the exhibition will not be significantly cut back due to the severe global emergency, especially since exhibition attendees were able to explore new products, technologies and services. The company’s staff found this Conexpo/Conagg quite successful, optimistically believing that the show ‘must go on’.
