Product Introduction
The SQ14SK4Q boasts a maximum lifting capacity of 14 tons and a peak lifting moment of 350 kN·m, delivering exceptionally robust foundational lifting performance. Its boom is constructed from high-strength steel featuring a unique hexagonal cross-section design, significantly enhancing the boom's resistance to bending and torsion while improving overall stability. A single hydraulic cylinder drives the synchronized extension and retraction of all four boom sections, enabling highly efficient and reliable operation.
Product Advantage
1.Throttle Control System
Changing the form of previous manipulation and throttle operation individually,Realization of the bilateral handle synchronous and driving throttle acceleration and deceleration automatically, due to the speed change steady,it can easily to carry out the lifting work.
2.End position automatic hook device
Maximum savings in preparation time before and after operation, to ensure that customer's vehicle could be in a driving state in the shortest time, and prevent crane damage accident caused by hoist swing to enhance the safety of driving.
3.Hoisting overwinder device
If a user is negligent or unfamiliar with the operation of lifting hooks,the hoisting overwinder device will stop hook raise in time, to prevent the safety of personal and property caused by fracture of wire rope.

Product Uses
1. Construction and Municipal Engineering
This crane is suitable for construction sites and municipal projects, efficiently handling the lifting of building materials such as precast slabs and steel reinforcement. Its powerful lifting capacity and flexible slewing operation enable safe and efficient work in confined urban environments, meeting diverse lifting requirements.
2. Mining and Quarrying
This crane can lift heavy materials like ore and stone in mining and quarrying environments. However, special attention must be paid to ground leveling, dust protection, and climatic conditions. Strict adherence to safety regulations and enhanced equipment maintenance are essential to ensure safety and suitability.
3. Logistics, Warehousing, and Cargo Handling
In logistics yards, warehousing centers, and port terminals, this equipment facilitates cargo loading/unloading and heavy material handling. Its 360° full rotation capability meets diverse operational demands in complex scenarios, enhancing efficiency for large-scale cargo handling.
4. Equipment Installation and Large Component Lifting
In factories, workshops, or energy projects, it supports heavy equipment installation, maintenance, and large component lifting. Its 14-ton rated lifting capacity and excellent working radius address diverse heavy-tonnage hoisting requirements.
5. Overseas Construction Projects and Specialized Applications
This crane model has been exported to regions like Ethiopia for local construction projects. Its robust lifting performance and adaptability to specialized conditions enable effective operation in international markets and demanding work environments.
Product Operate Guide
Operating the SQ14SK4Q requires a Special Equipment Operator Certificate. Conduct a comprehensive inspection of the equipment before operation to confirm the integrity of the wire rope, hooks, and safety devices. Fully extend the outriggers on solid, level ground to ensure stable support. Strictly adhere to the load chart (maximum lifting capacity: 14 tons). Overloading is strictly prohibited. Maintain smooth movements during operation, utilizing the 360° full rotation and four-section boom's synchronized telescoping capabilities for precise positioning. Continuously monitor the surrounding environment; never pass loads over personnel. Conduct regular inspections and maintenance of the hydraulic system. After completing operations, fully retract the boom to the transport position and disconnect the power supply.
FAQ
1. HYDRAULIC CYLINDER ROD SHAKES DURING EXTENSION?
Air ingress into the rodless chamber or slight piston rod bending. Require purging or professional calibration.
2. EQUIPMENT EXPERIENCES BRIEF LOSS OF CONTROL AFTER PROLONGED PARKING ON SLOPES?
Gravity-induced spool displacement in the main control valve causes pressure loss in one cylinder chamber. Normal behavior as hydraulic fluid requires time to replenish during subsequent operation.
3. FOAMING INSIDE THE HYDRAULIC OIL TANK?
The return line inlet is positioned above the oil level, or the seal on the separate return filter element has failed, causing return oil to impact the surface and draw in air. It could also be due to incorrect oil type.
4. AFTER A COLD START, THE HYDRAULIC PUMP EMITS A BRIEF SCREECHING SOUND WHEN THE EQUIPMENT RUNS AT FULL SPEED IMMEDIATELY?
During cold starts, the oil is viscous, increasing suction resistance in the pump and causing “cavitation.” Idle for several minutes to preheat the hydraulic system.
5. ENGINE RPM REMAINS UNCHANGED WHEN PRESSING THE MANUAL THROTTLE INCREASE BUTTON?
This is not a hydraulic fault but an electronic control issue. Inspect the throttle controller, sensors, and wiring.
6. DATA OCCASIONALLY FLUCTUATES ON THE DISPLAY?
Caused by unstable sensor supply voltage, signal line interference, or poor grounding.
