Reducing Environmental Impact
Energy consumption and environmental impact are becoming increasingly important when a company invests in new material handling equipment. In other words, nowadays the impact on the environment caused by a material handler needs to be minimized. Additionally, the cost to handle one ton of bulk material also has great importance, as this shows the economic feasibility.
As a result, over the last few years, there has been a tendency towards more energy efficiency.
Several manufacturers now supply material handlers with hybrid systems, where the energy that is released during the boom down function is stored into accumulators. When the boom is lifted, the stored energy is utilized to support this movement. Usually an additional cylinder is required in combination with an energy storage system. Suppliers claim to save customers 30-35 % on their energy bills.

t the same time, more and more electrically powered machines
are becoming available, instead of the traditional diesel powered
material handlers.
E-Crane Leading the Way
At E-Crane®, they have been doing things quite differently for the last 25 years. Utilizing the principle of equilibrium, where the stick is connected to the rotating counterweight by means of a connecting rod, the load can be moved from point A to B at a fraction of the energy usually required. The energy savings accomplished using hybrid systems is insignificant in comparison. The philosophy is simple; start with an energy efficient design rather than adapting to a fundamentally inefficient one.
Gravity Working for You
On an E-Crane®, the center of gravity of the machine always stays within the slewing ring as the movement of counterweight and stick are synchronized. As a result of this, a balanced state is maintained and guaranteed at all times. When working with lighter loads, the movable counterweight moves the stick out almost spontaneously as it pulls the boom up. When working with heavier loads, the movable counterweight assures that smooth lifting is possible at low hydraulic working pressures.
