The TranzVolt Top Cap by Tie Down Roofing is a necessary component of the TranzVolt ladder hoist. The Top Cap replacement part attaches easily to the top of the track system. This product holds the pulley in place, so the carriage moves up and down with materials. The development of the TranzVolt began when several companies approached Tie Down, looking for a more efficient and effective platform hoist kit. Tie Down worked directly with these companies to identify solutions for multiple industries. The TranzVolt Platform hoist lift saves time in setup and operation, allowing contractors better efficiency when installing solar panels and lifting more materials. Tie Down Safety maintains high standards and quality control through quality raw materials and components made in the USA.
