The 23‑meter truck‑mounted crane with square outriggers is designed for lifting operations that require both long reach and reliable stability. Its key structural feature is the use of square-section outriggers, which provide a strong, torsion‑resistant base to support the telescopic boom throughout its working range. This configuration allows the crane to operate efficiently in urban construction, infrastructure maintenance, logistics yards, and on‑site installation work where space and ground conditions may vary.The machine is typically built on a medium‑duty commercial truck chassis, combining highway mobility with on‑site maneuverability. The 23‑meter boom length enables operators to perform hoisting tasks such as lifting roofing materials, steel components, prefabricated panels, small machinery, and utility equipment to mid‑rise levels or over obstacles. Its lifting capacity is graded according to outreach, with higher loads handled near the base and lighter loads at maximum radius, in line with international load chart standards.Square outriggers are arranged in a conventional four‑point layout, extending laterally and vertically to transfer load forces from the upper structure to the ground. The square cross‑section offers higher bending and compression resistance than comparable light‑duty designs, enhancing stability during slewing, telescoping, and luffing operations. Outrigger extension is usually hydraulically driven, with independent controls that allow partial or full extension to adapt to tight sites, roadside work, and uneven terrain. Integrated locking pins, check valves, and safety interlocks help prevent unintended retraction and support secure working conditions.The crane’s upper structure consists of a slewing platform, hydraulic winch, telescopic boom sections, and control system. The boom is fabricated from high‑strength steel, with internal wear pads and synchronized telescoping cylinders or rope‑type mechanisms to maintain smooth extension and retraction. Slewing is powered by a hydraulic motor and gearbox, providing 360‑degree rotation with controlled acceleration and braking to minimize load swing.Hydraulic systems form the core of all lifting and positioning functions. A gear or piston pump, driven by the truck’s power take‑off, supplies pressurized oil to cylinders and motors through a proportional control valve block. This arrangement enables simultaneous operations, such as lifting, telescoping, and slewing, while maintaining predictable control response. Load‑holding valves and counterbalance valves are installed on critical circuits to ensure that the boom and load remain stable even in case of hose failure or pressure fluctuations.Safety and operational reliability are supported by multiple protection features. A load moment limiter or overload warning device monitors working conditions, providing alarms or limiting movements when operating near rated capacity. Level indicators allow the operator to verify ground setup, while emergency stop switches and manual descent functions support response to unexpected situations. Non‑slip steps, guardrails, and clearly marked controls contribute to ergonomic and safe daily use.Routine applications for this type of 23‑meter crane include building material delivery, streetlight and sign installation, small tower assembly, rooftop equipment placement, and general maintenance work. The combination of a road‑legal carrier, robust square outriggers, and a mid‑height telescopic boom makes it a versatile lifting solution for contractors, service providers, and fleet operators who require both reach and stability in a compact, mobile package.
