Differs from lower loading capacities in that it is composed of two coupled trolleys and two pulley blocks.
The Z220/15t – 20t is manufactured with a basic lift height of 5m. Greater lift heights must be given in the order.
The width of beam b can be modified to the customer’s wishes.
We only recommend it for travelling along profiles with a straight flange (” HEB” type profiles).
However the travel wheels of the travelling pulley block enable it to move also along profiles with a slanted flange.
