ability to curb production costs only, but to- day it is more than just that, with customis- ation, the ability to tailor the product to suit customer needs, taking centre stage. “The total value proposition is the most important consideration in today’s buying decisions, all the way from product quality, price, financing through to service and maintenance,” says Sampson. Machines in detail The new SANY 956H5 wheel loader, recently introduced to the local market by GEM, is powered by a Cummins QSL8.9 engine, which ensures more power, high efficiency and large displacement. Its multipoint fuel injection allows for immediate throttle response, enhanced fuel efficiency and reduced noise. It features a customised DANA axis-shift transmission with electronic control system, which allows for automatic shifting. The solenoid valve and the logic control achieve a much smoother shifting and faster response for improved productivity. The loader also comes with a high-pres- sure load-sensitive hydraulic system, per- fectly matching speed and power, resulting in a 10%-15% energy saving. The 25 MPa high-pressure hydraulic system and main valve of large displacement achieve higher breakout and lifting force. The new SY335C hydraulic excavator, which also recently made its debut in South Africa through GEM, is a true testimony to SANY’s relentless focus on research and development. It is a radical upgrade of the previous 30 t excavator range. A big talking point is the latest Kawasaki large-torque swing mechanism employed, which increas- es rotary torque by 32% from the original 100,6 kN.M to 132.8 kN.M. The SY335C is powered by the 6HK1- XABEA-08-C2 Isuzu engine specifically customised for SANY. A quick circuit has been added to the arm oil cylinder circuit. When the arm oil cylinder is extended, the oil return circuit is cut off and hydraulic oil flows from the return circuit into the cylin- der via a check valve. The hydraulic oil in the arm cylinder rod end does not return to the tank but goes directly to the cylinder head end. The arm speed is increased as a result and fuel consumption is low under this condition. The auto deceleration system reduces fuel consumption by 5-10%. When an operation has been stopped for three seconds, the en- gine speed drops automatically to idling level and maintains the idling state, thus cutting down on unnecessary fuel consumption. “When the operation resumes by moving the control levers, the engine speed will increase to the set rpm within 0,1 second,” concludes Sampson. b

equipment is a thing of the past. He reasons that in today’s operating conditions, an OEM, together with its dealer, must be in a position to customise their product as per customers’ requirements. He is of the view that customised solutions are required to suit the fast-changing and varied customer requirements. “It is no longer enough to create one machine and expect it to suit

the needs of all. Fleet owners have become more educated and demanding in terms of wanting machines suited to the kind of work and environment that they work in,” says Sampson. A recent McKinsey & Company report corroborates Sampson’s views, stating that in the past, the most competitive edge in construction and mining equipment was the
