End Carriage: 1. It is made of rectangular steel-pipe or steel plate by welding, the finished end carriage get 1-time positioning process on numeral control machine in order to ensure dimension accuracy and fit tolerance. 2. Each end carriage is supplied with wheels with double-wheel rim, buffer and anti-derailing protection device. |
1)Electric parts and electric hoist are packed by strong plywood crate, others packaged in plastic woven cloth. 2) Make iron frame to ensure end beam and accessories not be lost during transportation |
