Today, cranes & winches (hoists) are important tools for a wide variety of applications in industries, widely used in manufacturing, cargo transport, construction and more.
In general, cranes are divided into 3 types: cranes, cable cranes and gate cranes. Most driven crane solutions adopt discharge resistors to convert the renewable energy during operation into heat and dissipate it. Through actual survey, most of the current solutions use wasteful amount of power and do not pay attention to the rate of power consumption.

Introduction of the VFD-C2000 inverter, VFD-E inverter and REG2000 energy converter
Edge girder cranes are the most common of all types of overhead cranes. Delta has provided a girder overhead crane solution using VFD-C2000 inverter to control lifting. VFD-E inverter compact design for traveling control. In addition, the solution using a REG2000 energy regenerator is used to replace the discharge resistor, with an energy regenerator that enhances energy savings.
In most traditional crane solutions, the discharge resistor converts the renewable energy into heat and dissipates it. Discharge resistors require regular maintenance to ensure safety and stability, and traditional crane solutions waste both electricity and cost.
Delta's crane solution solves this problem with the REG2000. When powering VFD-C2000 inverter and VFD-E inverter, the system automatically transmits regenerative energy generated during braking, starting or shifting to REG2000. At that time, the REG2000 will convert renewable energy into usable energy and transmit it to the grid for reuse, energy saving efficiency is over 95%.

The energy saving solution for crane industry is widely and successfully applied in the UK
Softstart UK is one of the UK's leading and fastest growing suppliers of motor control and automation equipment. With sales of over 2.3 million USD in 2008 - 2009, the company offers a wide range of products from companies around the world and is capable of manufacturing complete engine control systems and medium voltage soft starters.
Delta Iindustrial Automation Business Group (IABG) and Softstart UK first met at the famous Hannover Messe Exhibition in 2012 and with similar business views they became partners shortly after the end of the event. As the main distributor of Detla in the UK. Softstart UK has put great effort into product promotion and sales. At Hanover Messe 2012, Softstart UK received the award for excellent sales growth unit and is a new EMEA partner in 2013.
Together with Delta IABG, Softstart UK has provided a green automation solution for customers in the UK. Through the efforts of Softstart UK, the girder overhead crane solution has been successfully applied to cranes and winches (hoist) in a number of major ports in the UK, and received positive feedback and comments. . Delta IABG also shared its crane solution for the year that took place at Hannover Messe 2012 and its successful applications at the IABG seminar during the event.
