Product Description
The SQZ1500 is a high‑capacity heavy‑duty knuckle‑boom truck‑mounted crane, designed for confined‑space heavy‑load lifting operations. With a rated maximum lifting moment of 143t·m, it reaches 19.4 m maximum working radius and 22.5 m maximum lifting height. Its compact folded boom structure greatly reduces overall occupied space, making it suitable for indoor workshops, narrow urban streets and low‑clearance job sites where straight‑boom cranes cannot work.
Adopting multi‑section folding boom and advanced multi‑circuit hydraulic control system, the crane realizes flexible boom folding, smooth luffing, slewing and lifting compound actions. High‑strength alloy steel boom improves structural rigidity and anti‑fatigue performance. Standard safety protection devices including load moment limiter and outrigger monitoring system guarantee operational safety. This folding truck‑mounted crane can be matched with different truck chassis, widely used for equipment installation, cargo handling, municipal maintenance and rental business.
Product Advantages
Compact Knuckle‑Boom Structure for Narrow Space Multi‑section folding boom design, small storage dimension after folding. Perfect for low‑height workshops, narrow urban roads and indoor hoisting tasks which traditional straight‑boom cranes cannot access.
Powerful Lifting Performance Max lifting moment 143t·m, max working radius 19.4 m, max lifting height 22.5 m. High‑strength alloy steel boom resists deformation under heavy load, meets heavy‑duty material handling requirements.
Reliable Multi‑circuit Hydraulic System Precise hydraulic control supports smooth compound movements of folding, luffing, slewing and hoisting. Stable load‑holding performance avoids cargo slipping. Good adaptability for long‑time continuous working.
Complete Safety Protection System Equipped with load moment limiter, outrigger status monitoring, overload alarm and emergency stop function. Effectively prevent overturn and overload risks, improve site operation safety.
Strong Chassis Adaptability & Easy Maintenance Compatible with multiple heavy‑duty truck chassis. Core hydraulic and structural components adopt globally common spare‑parts, convenient for daily inspection and after‑sales maintenance.

Operation Guide
Pre‑operation Check Inspect hydraulic oil level, boom structure, steel wire rope, outriggers, load moment limiter and alarm devices before starting. Check ground bearing capacity for outrigger supporting area.
Outrigger Deployment Fully extend H‑type outriggers and level the crane body. Never lift loads with partially deployed outriggers. Keep safe distance from overhead power lines.
Lifting Operation Strictly follow lifting performance chart. Forbid overload operation. Operate control levers gently to avoid sharp jerk during folding, slewing and hoisting.
Transfer Preparation Fold boom completely and fix hook block before truck driving. Observe local road transportation regulations.
Daily Maintenance Lubricate boom hinge points and slewing bearing after each shift. Check hydraulic pipe joints for leakage. Replace oil and filters per official maintenance manual.
Warning: Only certified professional operators are allowed to operate this knuckle‑boom crane.
FAQ
Q1: Does SQZ1500 include the truck chassis?
A: No. SQZ1500 is only the knuckle‑boom crane upper unit. You need to match it with qualified heavy‑duty truck chassis.
Q2: What is its biggest advantage compared with straight‑boom truck cranes?
A: Folding knuckle‑boom structure occupies smaller space after folding. It can work in narrow streets and low‑clearance indoor workshops where straight‑boom cranes cannot enter.
Q3: What is the shipping packing method?
A: Nude packing for sea transportation. We can provide shipping marks and full set of export documents.
Q4: What safety devices are equipped?
A: Load moment limiter, overload alarm, outrigger monitoring and emergency stop function are standard configuration.
Q5: Can I add optional attachments?
A: Multiple optional accessories such as grab bucket and lifting hook are available upon customer request.
Price Note
Final price depends on configuration, optional attachments, delivery term and order quantity. Please send your inquiry with your working‑condition requirements, we will provide formal quotation and complete export documents.
