Chinese heavy machinery and construction equipment manufacturer Sany has launched the STT4501E2-D – a fully-electric terminal tractor. With the electric terminal tractor Sany says it is responding to the increasing demands for reduced emissions, noise reduction, and economical operation. The model has been optimised for the European market and is available now.
The STT4501E2-D is built on a heavy-duty chassis and has a maximum tractive force for 75 tonnes of trailer load. The battery, with a capacity of 281.9 kWh, enables a range of up to 120 kilometres or an operating time of up to 18 hours.
The integrated thermal management system is designed to keep the battery within the optimum temperature range under continuous load, while an additional braking system increases braking energy recovery. The three-part electrical system has a protection class of IP67 and higher and uses a modern leakage detection system connected to Sany’s remote monitoring system.
According to Sany the fully electric drive results in noticeable savings in energy and maintenance costs during operation – especially in ports where machines are in use for many hours. It says the optimised battery capacity, long running times, and lower service requirements will help form the basis for a gradual switch to electric fleets for many operators.
“The STT offers exactly the performance profile that many of our customers are looking for: high availability, reliable range and economical operation,” says Daniel Zhong, sales director at Sany Europe. “The demand for electric solutions is growing noticeably – and with this model, we offer a mature alternative that has already proven itself in real-life port operations.”
