A self climbing concrete placing boom is designed for super high rise buildings where tower crane time is limited. Unlike mobile booms that need crane relocation, this hydraulic climbing boom climbs with the building structure. It attaches to the elevator shaft wall. It climbs floor by floor automatically. No tower crane assistance needed. The tower crane stays free for other lifts.
YG Machinery offers YG-HGY19, YG-HGY21, YG-HGY24, YG-HGY28, and YG-HGY32 self climbing concrete placing booms for core wall pouring and super high rise construction.

How a Hydraulic Climbing Boom Climbs?
The tower climbing concrete boom climbs with the building structure.
1. Anchoring to the elevator shaft – The climbing boom attaches to the elevator shaft wall or core wall. Stable mounting points hold the boom securely.
2. Hydraulic cylinder extends – The climbing cylinder pushes the tower mast upward. The 0-4m adjustable lifting height matches each floor height.
3. Locking mechanism engages – Automatic locking holds the mast in place at the new height. No manual bolting. No crane needed.
4. Climbing frame moves up – The climbing frame follows the mast. The boom is now ready at the next floor level.
5. Continuous repetition – Repeat for every floor. The elevator shaft concrete boom climbs as the building rises.
6. End of project – Disconnect the anchoring system. Lower the mast. Remove the boom. Ready for the next project.
No tower crane assistance required. The boom climbs itself while the crane handles other lifts.
Key Features of Hydraulic Climbing Boom
Automatic hydraulic climbing – Climb floor by floor with hydraulic cylinders. No tower crane needed. No waiting for crane availability.
Climb with building structure – The boom rises as the building rises. Always at the right height for core wall pouring.
Attach to elevator shaft wall – Stable anchoring in the elevator shaft or core wall. No floor space occupied.
No tower crane assistance – The tower crane stays free for rebar, formwork, and material lifts. Save 50-100 hours of crane time per project.
Telescopic tower mast – 0-4m adjustable lifting height. Adapt to different floor heights without modifications.
Stable truss structure – Steel truss mast provides stability at heights over 200 meters. Resists wind and vibration.
360° full rotation – Rotate a full circle from the core wall position. Cover the entire floor plate from a single location.
Multiple control options – Wireless remote, wired remote, or panel control. Choose what works for your site.
Designed for 200m+ buildings – HGY21 reaches 21m. HGY32 reaches 32m. Built for super high rise construction.
Customer Case: Super High Rise Core Wall Project
A construction company in the Middle East was building a 280-meter residential tower. The core wall required concrete pouring on every floor. The contractor used a mobile boom that required the tower crane for relocation. Each floor took 1.5 hours of crane time. Crane rental was $600/hour. The project was losing money on crane time.
The contractor switched to a YG-HGY21 self climbing concrete placing boom. The boom was installed in the elevator shaft. It climbed floor by floor automatically. The tower crane was freed for other work.
The results:
- Crane time saved: 50 floors × 1.5 hours = 75 hours
- Crane rental saved: 75 hours × $600 = $45,000
- Floor cycle time reduced from 5 days to 4 days
- The project finished 20 days ahead of schedule
- The boom paid for itself in 30 floors
The project manager said: “We were wasting crane time moving the boom on every floor. The self climbing boom eliminated that. The tower crane kept working. We finished faster and saved money. This is the only way to build tall buildings.” The climbing concrete pump worked seamlessly with the placing boom for continuous concrete delivery.
How to Choose the Right Self Climbing Concrete Placing Boom?
| Your project need | Recommended model | Why |
| Building 100-150m, medium core wall | YG-HGY19 (19m) | Lightweight, good for medium heights |
| Building 150-200m, standard core | YG-HGY21 (21m) | Most popular, balanced reach and weight |
| Building 200-250m, large floor plates | YG-HGY24 (24m) | Extended reach for larger cores |
| Building 250-300m, wide floor plates | YG-HGY28 (28m) | Long reach, stable at height |
| Building 300m+, very wide floor plates | YG-HGY32 (32m) | Maximum reach, highest capacity |
Consider your building height. The higher the building, the longer the reach needed to cover the floor plate from the core.
Consider your elevator shaft size. The tower mast must fit inside the elevator shaft. Check dimensions before ordering.
Consider your floor height. The 0-4m adjustable climbing height adapts to different floor-to-floor heights.
Consider your crane capacity. The self climbing boom does not need crane assistance, but the initial installation does require a crane lift.

Frequently Asked Questions
Q: What is the self climbing concrete placing boom price range?
A: Price depends on model (YG-HGY19 to YG-HGY32) and configuration. Contact us for a current price quote.
Q: How does it climb without a crane?
A: Hydraulic cylinders push the tower mast upward. Automatic locking holds it in place. No crane needed for climbing.
Q: Where is it installed?
A: Installed in the elevator shaft or core wall. The shaft provides stable anchoring points for the climbing mechanism.
Q: How high can it climb?
A: As high as the building. The tower mast sections are added as the building rises. The climbing mechanism continues up the shaft.
Q: Does it need tower crane assistance?
A: Only for initial installation. After that, the boom climbs itself. The crane is free for other work.
Q: What is the climbing speed?
A: 0.6 meters per minute. A typical 3-meter floor takes 5 minutes to climb.
Q: How is it anchored?
A: Anchored to the elevator shaft walls using structural anchors. The anchors transfer loads to the building structure.
