- The Yanmar Sigma Boom is a three piece offset boom which offers:
With its unique boom the B7-6 is able to work where no other excavator can: efficient when working at height but also when digging below the dividers between the shoring plates of a trench. Perfect to excavate in urban environments, its unique boom reduces truck rotations when loading or unloading: the bucket can go in the corners of the truck easily. The B7-6 is also very stable and its boom is very resistant due to the high tensile steel from which it is made of. High tensile steel is 1.5 times stronger than ordinary steel and is lighter which improves the weight repartition of the machine.
When working at boom offset in narrow trenches, the second part of the boom does not strike the left-hand shoring plate, as tends to occur with traditional excavators.
+ True Zero Tail Swing excavator
+ Smallest front turning radius of the industry with only 1320 mm
+ Ideal worktool for jobsites in densely populated areas and urban sites with limited space
+ Increased efficiency and productivity of the machine
+ Lower impact on traffic congestion
+ Improved safety for the operator
UNIQUE BOOM CONCEPT
Yanmar developed for the B7-6 a unique boom concept. It offers a three piece offset boom, made out of high tensile steel, which is 1,5 times stronger than normal steel. The Sigma boom has several big advantages due to the specific cinematic, it offers the best dumping height – digging height in its class, combined with extraordinary digging depth:
The Sigma boom offers at the same time the best visibility on the attachment and the working area of the industry. This reduces greatly the stress for the operator and improves at the same time safety and productivity.
The dipperstick and attachment can even get under an obstacle, because of the flexibility of the cinematic.
The second articulation of the boom provides the offset on lateral movement of the workgroup and attachment without rotation of the upper frame. This offers enormous gain in productivity and visibility for the operator.
MAXIMUM STABILITY AND EXCEPTIONAL LIFTING STRENGTH
The B7 Sigma-6 has an exceptional stability due to its unique boom design, since the pivot point of the boom is located close to the center of gravity of the machine. Therefore, the B7-6 is the optimal tool to lift and place loads. Furthermore, the B7-6 is equipped with the patented VICTAS system. This unique track system proposing an offset rolling path enables the excavator to lift loads with increased performance while having the most compact size in its class.
+ UNIQUE UNDERCARRIAGE
The X-shaped, box section structure of the undercarriage provides excellent resistance to torsional bending. The frame is designed for maximum durability.
+ POWERFUL YANMAR ENGINE
The B7 Sigma-6 benefits from the most advances technology of the leading manufacturer of industrial diesel engines. The 53,5 HP TNV engine is equipped with direct injection to create clean burning power. It has fully-electronic control to provide the B7 Sigma-6 with total intelligent engine control. The engine is also equipped with a common rail system to allow fine-tuned electronic control of fuel injection.
+ ELECTRICAL CONTROL SYSTEM EGR AND DPF
The Yanmar engine is already fully compliant with EU Stage V requirement, meaning that our engine has cleaner emission than required today. This is achieved through two additional features. The first is the cooled EGR (Exhaust Gas Recirculation) which reduces drastically the nitrogen oxides (NOx). The second is the DPF (Diesel Particulate Filter) to clean up exhaust emissions (PM). Yanmar has successfully developed an exclusive regeneration system in order to combat clogging and cleaning down-time.
+ VIPPS HYDRAULIC CIRCUIT
The B7 Sigma 6 is equipped with a hydraulic circuit with aggregated power regulation equipped with three variable flow piston pumps and a multiple combination directional control valve. Pumps engage automatically depending on the operation being performed, providing greater ease of use for the operator. On one hand, the combination of the pump flows can increase the work speed and on the other hand, the system allows smooth and simultaneous performance of all the operations, even while travel.
+ ADJUSTABLE PROPORTIONAL CONTROL OF THE AUXILIARY CIRCUITS
The B7 Sigma-6 is standard equipped with two auxiliary hydraulic circuits. Both are operated via a proportional control located on the joystick which adapt the flow and the direction of the oil flow. Additionally each circuit has an easy to operate potentiometer to adjust the oil flow to the optimal requirement for each and every attachment.
SPACIOUS AND COMFORTABLE CABINE
Yanmar has been paying a lot of attention to the operator station with this ultimate version of the B7 Sigma-6. We have considerably increased the space inside the cabin by increasing the width and the length of the cabin. As a result the cabin offers 40% more space to the operator for an improved comfort.
+ COMFORTABLE ADJUSTABLE AIR-SUSPENDED SEAT
+ REDUCTION OF THE NOISE LEVEL
+ IMPROVED AIR CONDITIONING
+ 360° VISIBILITY
The structure of the B7 Sigma-6 cabin has been designed to meet the ROPS (Roll-Over Protective Structure) certification as well as the FOPS (Falling Object Protective Structure) level 1. The FOPS level 2 protective structure is optionally available as well as a front guard.
+ LED LIGHTING EFFICIENCY AND LOW CONSUMPTION
In order to work safely, efficiently and with accuracy in the darkness, the B7 Sigma-6 comes standard with 3 LED lights, one positioned on the inner part of the boom, and two at the front of the cabin. The LED technology provides a powerful light while reducing energy consumption and this increases the service life of the battery. An optional beacon and additional LED rear light can be added.
The structure of the undercarriage, as well as the steel covers provide an optimal protection and longer service life. All hoses are protected with abrasion-resistant sleeves. Furthermore, a lot of care has been paid to the hose routing on the working equipment, and all hoses are covered with steel plates. These measures enhance the service life and reduces downtime of the machine. The blade and the boom cylinder are also fully protected by steel plates
Daily maintenance has to be performed easily. There is one easy to open engine bonnet and the right-hand side cover is mounted on one hinge to open easily. This gives an access to all major elements: air filter, A/C compressor, radiator, refueling pump, battery, fuel tank, hydraulic oil tank, alternator, engine oil dipstick, water separator, coolant level, etc…
The B7 Sigma-6 is equipped with the newest digital interface that informs the operator in real time about the status of his machine. Perfectly integrated into the righthand console, the 3.3” screen provides excellent visibility. The interface provides the customer with useful information through LED lamps, or indications about important elements like fuel consumption, fuel gauge, coolant temperature gauge, etc… The interface assists also the customer for maintenance intervals and to program such interventions. The interface works also as a diagnostic tool in case of malfunction by sending an error code and an information icon on the display.
SmartAssist Remote is the new fleet management system developed by Yanmar wich gives you optimal visibility on your equipment location and status using the latest telematic technology.
This compact piece of equipment, available as standard on selected Yanmar carrier and crawler excavators, will help you maximize your work potential. By providing real time information, it gives you total control and lets you monitor and manage your machines remotely via a PC or Smartphone.
