When Multiple Buildings Share A Single Tower Crane, How Can Lifting Routes Be Optimized To Minimize Waste Associated With Material Transfer?

In clustered residential projects, a single tower crane often serves multiple buildings. Poorly planned hoisting routes-characterized by frequent back-and-forth hook movements and long-distance empty runs-not only extend the duration of individual lifts but also waste fuel and labor hours, directly slowing down the overall construction schedule.
To reduce inefficient transfers, first establish designated work zones in advance. By utilizing the crane's 70-meter maximum slewing radius, assign a specific operating sector to each building; this prevents long-distance shuttling between buildings, minimizes the slewing angle, and significantly shortens the trolley's travel distance.
Second, strategically arrange material storage yards. Locate stockpiles for key materials-such as rebar, formwork, and masonry blocks-near the crane's slewing center to minimize horizontal lifting distances and eliminate the need for repeated long-distance transport from remote storage areas. Additionally, coordinate tasks by time of day-hoisting structural rebar in the morning and masonry materials in the afternoon-to avoid the inefficiency of constantly switching between pickup and drop-off points.
Furthermore, optimize the hoisting schedule. When multiple crews are working in shifts, establish a clear hoisting sequence for the buildings to ensure continuous operation. This minimizes downtime caused by frequent crane starts and stops and prevents inefficient empty slewing caused by abrupt direction changes between buildings. For cross-building operations, strictly define slewing paths to reduce wasted travel resulting from wide-angle turns.
Rational planning of work zones, material yard locations, and hoisting sequences effectively reduces empty hook travel and increases a single crane's effective operating time by over 20%. This significantly boosts material hoisting efficiency for clustered residential projects-without additional equipment investment-and effectively controls labor and machinery costs
