The 32 meter booms gain added versatility with the quick disconnect feature. Contractors use the truck-mounted pump with placing boom in its conventional mode for part of a day on slab pours or other ground level placements and quickly remove the boom (with the aid of a tower crane) for remote placements later in the day. The quick coupling incorporates four pins which are easily removed to free the boom from the truck. The boom is remounted to a pedestal using the four pin system.
