2. Working Principle
The stable narrow-space ultra-high altitude operation of SINOTRUK 25m boom lift truck relies on heavy-duty SINOTRUK chassis power transmission, multi-section articulated folding hydraulic linkage system, 360° full rotation slewing driving mechanism, intelligent safety interlock monitoring module and optional auxiliary hoisting hydraulic branch circuit, realizing long-distance vehicle transit, obstacle-crossing ultra-high lifting, omnidirectional positioning and integrated light cargo hoisting synchronously.
The 258HP high-power SINOTRUK chassis provides stable traveling power for cross-city multi-site scheduling on municipal and bridge construction projects. After arriving at the working area, operators fully extend and level hydraulic stabilizing outriggers and activate chassis parking lock before switching to aerial working mode; the built-in horizontal monitoring sensor will automatically lock all lifting hydraulic output if outriggers are not fully deployed to prevent vehicle tipping on uneven ground.
Chassis power take-off transmits engine power to the dedicated hydraulic station, and steady pressure oil drives multi-group hydraulic cylinders to push the multi-section articulated folding boom to complete sequential folding, stretching and luffing movements, steadily reaching the rated 25-meter maximum working height. The hydraulic slewing bearing independently drives the entire boom and bucket assembly to rotate 360° horizontally, freely adjusting operation azimuth without chassis displacement. Relying on multi-angle bending characteristics of articulated boom, the equipment bypasses trees, bridge piers and building walls to extend into narrow confined working zones for targeted construction tasks.
For models equipped with small lifting hooks, an independent auxiliary hydraulic circuit outputs stable traction force to finish lightweight material hoisting work. Real-time sensors continuously monitor chassis tilt angle, platform load and outrigger extension status; once exceeding safe threshold values, the safety control system instantly cuts off hydraulic power and triggers audible-visual alarms to block dangerous operations in advance. All hydraulic actions adopt proportional flow control for smooth stepless adjustment without jitter, improving long-hour high-altitude operation comfort and structural service life.
3. Daily Application Scenarios
Featured with heavy-duty high-load chassis, 25m ultra-high working height, flexible folding boom obstacle avoidance and optional light hoisting function, this export-grade SINOTRUK boom lift truck adapts to various indoor and outdoor narrow-space high-altitude construction scenarios, widely purchased by overseas bridge engineering contractors, municipal property maintenance enterprises, landscape greening companies and large venue operation management teams:

Different from short-height straight boom aerial vehicles limited to open flat construction sites, this multi-section folding boom model can freely shuttle through various barrier-rich narrow spaces, covering ultra-high altitude operation demands of municipal, bridge and landscape industries simultaneously. The integrated personnel maintenance and light cargo hoisting design reduces the quantity of supporting equipment on site, effectively lowering comprehensive procurement and leasing costs for overseas engineering teams.
4. Comparison with Traditional Models
Compared with short-wheelbase light aerial lift trucks: Conventional lightweight aerial vehicles adopt short wheelbase and low-power chassis, with insufficient bearing capacity under full load and poor stability during 20m+ ultra-high altitude operation. This SINOTRUK model uses 4700mm extended wheelbase and 258HP high-torque chassis, with reinforced body structure to guarantee stable lifting at 25m working height without body deflection.
Compared with straight telescopic boom aerial work vehicles: Ordinary straight boom lifts lack multi-joint bending structure, unable to detour around dense bushes, building partitions and bridge piers, generating massive construction dead angles in narrow complex sites. The multi-section articulated folding boom of this product realizes multi-angle flexible obstacle surmounting to reach confined working areas unreachable by straight boom equipment.
Compared with single-function folding boom aerial vehicles: Basic folding boom lifts have no reserved mounting interfaces for lifting hooks, unable to realize lightweight material hoisting and requiring separate small cranes for auxiliary material handling. Partial configurations of this SINOTRUK boom lift truck integrate boom-tip lifting hooks to complete maintenance and hoisting work with one machine.
Compared with uncertified secondary refitted aerial equipment: Miscellaneous chassis refitted aerial vehicles lack standardized hydraulic folding systems and complete export certification documents, with unstable boom bending performance and hidden safety hazards. Original SINOTRUK heavy-duty chassis matched factory integrated hydraulic assembly owns full customs clearance and safety audit qualification, eliminating cross-border trade registration obstacles.
