ccording to Modern’s 2020 reader survey1
, forty per
cent of respondents use strapping or banding to affix loads with the pallet. But, as
anyone who’s worked preparing strapped pallets knows, manual methods require much bending and movement, which places repetitive stress on the spine and joints. ErgoPack has long focused on the challenge of pallet load strapping to reduce these ergonomic stresses and the resultant time off due to back pain. Since patenting
the world’s first ChainLance strapping device in 1999, they’ve established themselves as a premium mobile pallet strapping system supplier.
All electrically powered models operate in more or less the same manner. The mobile unit, about as wide and high as an airport baggage trolley, is rolled alongside the pallet and its load. The strap is then pulled through the pallet and over the load using the ChainLance, leaving the free end within reach of the operator. From here, the operator receives the other end from a strap

lifter before welding the strap in place using an integrated sealing head (Figure 1). To ensure mobility, ErgoPack units are powered by rechargeable batteries, the chemistry of which varies with the model chosen. Connecting the unit for charging must be intuitive, safe, and simple. This is where EPH Elektronik Produktions- und Handelsgesellschaft mbH comes in, implementing the system’s electronics. The ErgoPack E-conomy Line (Figure 2) requires a 24 VDC output to charge AGM (absorbent glass mat) lead-acid batteries. The engineering team conducted an initial review of the requirements and identified a standard product from the lead-acid battery
charging range by Mascot, the Norwegian electronics specialist, the Model 2641 LA2
, a wide input-range charger design with dual 12 V + 12 V output in a plastic housing. The dual outputs enable two 12 V batteries of a 24 V system to be charged independently without needing complex battery management system (BMS) electronics.
ErgoPack prides itself on strapping systems that are easy to learn and intuitive to use. Furthermore, logistic centres
