Russia Construction Site Project: 4 Sets of HGY21-3 Mobile Hydraulic Concrete Placing Boom Delivered & Put Into Use
Project background
Severe cold climate & scattered construction plots bring huge concrete pouring difficulties
This large-scale comprehensive construction project is located in central Russia, covering multiple scattered building plots including residential communities, commercial supporting buildings and municipal auxiliary structures. The local area features typical subarctic climate: long cold winter, large day-night temperature difference, frequent strong winds, and hard frozen soil on the construction site all year round. Meanwhile, the project adopts segmented cross construction, with frequent site shifting and narrow on-site operating space, putting forward extremely strict requirements for concrete pouring equipment.
Before cooperating with Uniquemac, the construction team adopted traditional manual concrete distributing pipes and fixed concrete placing booms, and encountered three prominent construction bottlenecks:
Poor site mobility, low cross-region construction efficiency
Fixed concrete placing booms cannot be moved freely. Frequent disassembly, assembly and hoisting are required when switching different construction areas. Each relocation takes more than 6 hours, seriously delaying the overall construction schedule.
Unable to adapt to severe cold working environment
Ordinary placing booms have poor hydraulic system low-temperature resistance. Hydraulic oil is easy to condense at minus 30℃ low temperature, resulting in unsmooth boom rotation, stuck arm support and frequent equipment failures, greatly affecting continuous concrete pouring operation.
High labor cost and limited pouring coverage
Manual pipeline laying requires 5-6 workers for matching operation, with high labor expenditure. The effective pouring radius of traditional equipment is short, and there are many pouring dead corners on floors and wall structures, leading to uneven concrete pouring quality and high rework rate.
To solve the above pain points comprehensively, the Russian project contractor finally customized and purchased 4 sets of HGY21-3 mobile hydraulic concrete placing booms from Uniquemac professional manufacturer, realizing full-mechanized, high-efficiency and low-fault concrete pouring adapted to local severe cold construction conditions.
Customized HGY21-3 mobile hydraulic placing boom tailored for Russia severe cold construction
Equipment selection & targeted optimization design
Equipment model: HGY21-3 mobile hydraulic concrete placing boom
Order quantity: 4 sets
Core customized optimization aiming at Russian local working conditions:
Low-temperature resistant hydraulic system: Equipped with special anti-freezing hydraulic oil and sealed parts resistant to -40℃ ultra-low temperature, avoiding hydraulic system condensation and jamming in cold winter, ensuring stable hydraulic lifting and 360° full rotation of the boom.
Integrated walking chassis design: Built-in tracked mobile chassis, no need for secondary hoisting and disassembly. The whole machine can walk freely on frozen soil, muddy roads and uneven construction ground, realizing one-click free shifting of the whole machine within 10 minutes.
21m ultra-long pouring radius: Meet large-area floor concrete pouring demand of high-rise buildings, cover all construction dead corners, match on-site concrete pump perfectly, realize uninterrupted long-distance concrete conveying.
Wind-resistant reinforced boom structure: Thickened high-strength manganese steel boom overall welding, added wind-resistant support structure, adapt to frequent strong wind weather on Russian construction sites, effectively preventing boom shaking during high-altitude operation.
On-site equipment delivery, installation and commissioning process
Considering Russia’s long customs clearance cycle and remote transportation distance, Uniquemac adopted integrated overall packaging delivery, avoiding scattered part loss during long-distance sea and land transportation. Our professional overseas after-sales engineer team arrived at the construction site synchronously after equipment arrival, and completed overall machine installation, low-temperature debugging, operator training and whole-machine inspection within 3 working days.
Whole-site one-stop service covers equipment operation specification training, daily low-temperature maintenance guidelines, common fault quick troubleshooting, helping local construction workers master equipment operation skills quickly without extra technical cost.
Standard on-site construction process
Site positioning & machine shifting: Push the mobile placing boom to the designated pouring area through the walking chassis, fix the supporting legs stably, and complete horizontal calibration of the whole machine.
Hydraulic boom adjustment: Adjust boom height, horizontal angle and rotation range via remote hydraulic control panel, accurate positioning without manual pipeline adjustment.
Automatic concrete pouring: Connect with on-site concrete pump for synchronous operation, realize uniform and continuous concrete distributing, match local anti-freezing concrete formula perfectly.
Quick shifting after single-area construction: Finish pouring of one construction area, retract supporting legs directly, move the whole machine to the next working area rapidly, no need to cut off pipelines or disassemble the boom.
Implementation effect
After 2 months of continuous on-site operation, 4 sets of Uniquemac HGY21-3 mobile hydraulic placing booms have brought comprehensive upgrades in construction efficiency, construction cost, equipment stability and pouring quality for the Russian project:
Construction efficiency improved by 45%: Free mobile design eliminates repeated disassembly and hoisting work; single machine can complete 800㎡ floor concrete pouring per day, greatly accelerating segmented construction progress.
On-site labor cost cut by 40%: Each placing boom only needs 1 operator to complete remote control operation, reducing dependence on manual pipeline laying workers.
Equipment failure rate reduced to nearly zero in low temperature: Customized low-temperature resistant hydraulic system runs stably all day under -35℃ working environment, no oil condensation or boom stuck faults.
Concrete pouring quality upgraded: Hydraulic stable feeding avoids concrete segregation and hollowing problems; overall pouring flatness fully meets Russian national construction acceptance standards, and project rework rate drops to 0.
Greatly shortened site conversion time: The whole machine can be shifted in 10 minutes, compared with 6 hours relocation time of traditional fixed placing boom, saving plenty of auxiliary construction time.
Customer feedback
| Project Construction Manager from Russian Client:
“We have been troubled by equipment mobility and low-temperature failure problems for a long time. After using Uniquemac HGY21-3 mobile hydraulic placing booms, all our construction pain points are solved perfectly. The equipment runs very stably in our cold weather, the remote hydraulic operation is simple, and the moving function saves us massive time on site conversion. More importantly, the factory provides super professional overseas after-sales guidance, which is much better than other suppliers we have cooperated with. We will purchase more matching construction machinery from Uniquemac for our follow-up infrastructure projects.” |
