The 'Battery Powered Electromagnetic Pit-Cover Lifter with Mechanical Assistance' (the invention) is designed to alleviate the laborious and potentially injurious manual-lifting component of removing heavy steel plate pit covers that conceal the conduits (or trenches) found in purpose-designed event, exhibition and convention centres. Although primarily designed for use in the live entertainment field, this invention has potential application in telecommunications, construction and other labour-intensive sectors where it is necessary to regularly lift and remove heavy steel plate pit covers. The invention features a linear actuator for mechanical assistance, where the first class lever provides a 3:1 or 4:1 lift ratio. The built-in linear actuator removes the need for an operator to provide this lifting force - thus significantly reducing the possibility of suffering a work-related injury through repetitive and heavy manual lifting.
