Abstract: Abstract:The new requirements of brake control circuit of builders hoists specified in the new national standard GB 26557—2011 “Builders Hoists for Persons and Materials with Vertically Guided Cages” was introduced. The problems existing in brake control circuit of present builders hoist were analyzed. The brake control circuit of builders hoist was analyzed, and the reformation measures were proposed. The reformed brake control circuit of the builders hoist can meet the requirements of the new national standard.
