Meccano Transporter Bridge SM 21

Suspension type transporter bridge with an automatic reversing mechanism, driven by a 20 Volt Meccano Motor. The mechanism needs very careful adjustment to make it work. The model itself is relatively easy to construct and needs a lot of space. L: 115 cm ( 45.3“) H: 84,5 cm ( 33.2“) W: 37,5 cm ( 14.7“)
