Product Introduction
The new generation of small and light duty 5T knuckle type loader crane , with the maximum lift moment of 105 kN·m , maximum working range of 8.3m and rotation angle of 420°,the operation safety is improved greatly because it is equipped with alarm system.
Product Advantage
1. Warning system: while loader crane working, the caution light on the leg keep shining to remind the people and vehicle around. Avoid accident and ensure safety.
2. Stabilizer extension: single cavity nesting structure not only ensure the leg span but also reduced the installation space and crane weight.
3. Leveling mechanism of extension cylinder: this mechanism can carry out level regulation for extension cylinder, avoid the phenomenon of cylinder is not parallel to boom which arising from machining error of boom or structure distortion after long-term work, improve product external appearance and stress on the cylinder.
4. Large angle rack cylinder rotation: rack cylinder rotation, easy to repair and maintain, more economical and practical, rotation angle can reach to 420 °.

Product Uses
1. Urban Infrastructure and Municipal Maintenance
The SQZ105-3 is ideally suited for space-constrained operations such as urban construction sites, municipal pipeline networks, and renovation projects in older residential areas. Its compact design and flexible operational capabilities enable tasks including pipeline laying, small equipment hoisting, and landscaping, effectively minimizing disruption to daily life and traffic.
2. Transportation Engineering and Emergency Response
This equipment supports routine maintenance of roads and bridges, emergency rescue operations, vehicle recovery in traffic accidents, and obstacle clearance. Its excellent maneuverability and rapid deployment capability ensure timely responses to emergencies, safeguarding traffic flow and safety.
3. Logistics Transfer and Cargo Handling
The SQZ105-3 facilitates material loading, unloading, and transfer operations in ports, terminals, logistics parks, and factory warehouses. Its folding arm structure offers advantages in obstacle-crossing operations and can meet diverse loading/unloading demands across locations through “long-distance cargo transfer,” enhancing logistics efficiency.
4. Power Construction and Aerial Operations
In the power industry, this crane supports utility pole hoisting, transformer replacement, overhead line maintenance, and aerial inspections. Its 420° slewing angle enhances operational flexibility, accommodating construction requirements at multiple angles.
5. Specialized Industries and Unique Sites
The SQZ105-3 also serves in field engineering, airports, and specific industrial zones for equipment installation and maintenance tasks. Its alarm system significantly improves operational safety by preventing accidents.
Product Operate Guide
Before operation, check that the outriggers are fully extended and ensure the ground is solid. Keep the vehicle level during operation and never overload it. Fold the boom smoothly and slowly, maintaining a safe distance from surrounding obstacles. Rotate slowly and at a steady speed, avoiding abrupt stops or turns. Regularly inspect the wire rope for wear. After completing the task, retract the boom, secure the hook, and maintain daily equipment maintenance records.
FAQ
1. SHINY METAL SHAVINGS IN DRAINED ENGINE OIL?
Severe warning! Abnormal internal engine wear requires immediate inspection and repair.
2. TRACK PLATE BOLTS FRACTURED AT THE HEAD?
Insufficient bolt preload caused fatigue fracture under alternating loads.
3. MULTIPLE FAULT LIGHTS OCCASIONALLY TRIGGER FALSE ALARMS SIMULTANEOUSLY?
Loose or corroded ground connections in the vehicle's electrical system cause common-mode interference.
4. SIGNIFICANT DIFFERENCE IN HYDRAULIC SYSTEM NOISE BETWEEN COLD AND HOT ENGINE CONDITIONS?
Normal. Cold engine conditions increase oil viscosity, raising pump suction resistance and causing cavitation noise. After warming up, viscosity normalizes, with noise primarily originating from mechanical friction and fluid flow.
5. EQUIPMENT EXHIBITS JERKY, NON-LINEAR MOVEMENTS DURING PRECISE MICRO-OPERATIONS?
Poor flow regulation characteristics in the pilot control system, or wear in the micro-control section of the spool valve. Requires debugging or replacement of the master control valve.
6. WIRING HARNESS SHOWS WEAR AND SHORT CIRCUITS WHERE PASSING THROUGH METAL HOLES?
Rubber protective grommets are missing or uninstalled, allowing metal edges to cut through the harness insulation.
