Product Introduction
XGC75 system is mature and reliable with complete safety devices. Fitted with multiple advanced technologies, such as gantry self-erecting function, aux. hook quick release function, main and auxiliary hook block one-key switch function, slewing fine motion control and etc., the crane's performance is superior to that with other domestic brands in various aspects.
Product Advantage
1.Optimized design of transport and assembly/ disassembly
Basic machine is an integrated transport design, without disassembling track frame and boom base, greatly save transport costs and improve the assembly/disassembly efficiency. Unique A-frame gantry self-erection technology, no need of cylinder can achieve self- erection, to realize crane quick assembly. Single counterweight weighing no more than 4t, small auxiliary lifting equipment can achieve complete counterweight assembly.
2.Opimized hydraulic system design
Integrated design to reduce failure points, while reserve open space for assembly/ disassembly and maintenance.
Use of highly integrated LUDV main valve, with the functions of multi-complex operation, control of combined flow, high/low speed selection, to ensure operation efficiency. Optional unique independent bypass filtration in the industry, strong magnetic adsorption device, strengthened hydraulic system filtration, and anti-emulsifying ability.
3.Main/ auxiliary hook one-key-switch-over function
One-key-switch is used to easily achieve main/auxiliary hook switch-over, for wider range of applications.

Product Uses
1. Material Lifting in Mining Quarries
The XGC75 crawler crane is suitable for mining quarries. Its crawler design enables stable movement on uneven terrain and adapts to complex landscapes. With a maximum rated lifting capacity of 6.5 tons at the boom tip under single pulley conditions, it meets most heavy-load lifting requirements.
2. Transportation Infrastructure and Bridge Construction
This crane is widely used in transportation infrastructure projects. Its compact structure facilitates agile maneuvering and operation in relatively confined spaces, adapting to diverse working environments—including participation in major projects under Russia's extreme cold conditions.
3. Urban Construction and Equipment Installation
The XGC75 is suitable for urban construction projects and large-item lifting/transportation. Its advanced electrical control system and user interface enable precise operation by personnel, enhancing work efficiency and ensuring operational safety.
4. Energy Equipment Installation and Special Conditions
This equipment is also capable of handling tasks such as energy equipment installation. It can be equipped with various functional attachments—such as clamps and slings—based on actual requirements to meet different operational needs and enhance versatility.
Product Operate Guide
Before operation, inspect the stability of the outriggers and the integrity of the lifting gear. Maintain the crane in a level position during operation; overloading is strictly prohibited. Operate the telescopic boom steadily and slowly, ensuring a safe distance from surrounding obstacles. When traveling with a load, proceed at low speed and maintain stability; avoid sharp turns and emergency braking. Regularly inspect wire rope wear and the condition of structural connections. After completing operations, retract the boom, secure the hook, and maintain equipment maintenance records.
FAQ
1. WHAT IS THE RECOMMENDED INTERVAL FOR REPLACING OIL AND FILTERS?
Strictly adhere to the specifications outlined in the Operation and Maintenance Manual. Appropriately shorten the interval based on the severity of the operating environment (e.g., dusty, high-temperature conditions).
2. HOW SHOULD THE CORRECT HYDRAULIC OIL AND ENGINE OIL BE SELECTED?
Purchase genuine fluids matching the brand, grade, and specifications (e.g., viscosity grade, API/ISO standards) specified in the manual. Never mix different brands or grades.
3. WHAT PRECAUTIONS SHOULD BE TAKEN FOR LONG-TERM EQUIPMENT STORAGE?
Clean the equipment, drain all coolant (or fill with antifreeze), disconnect the battery negative terminal, fully retract all cylinder piston rods and apply rust-preventative oil, and elevate tires to prevent contact with the ground.
4. WHAT PRECAUTIONS SHOULD BE TAKEN DURING THE BREAK-IN PERIOD FOR NEW EQUIPMENT?
Strictly follow break-in procedures: reduce load and speed (typically below 70%-80% load capacity), monitor gauges closely, perform frequent inspections for tightness and lubrication, and promptly replace oils and filters during the first maintenance service.
5. WHAT CHECKS SHOULD BE PERFORMED BEFORE DAILY STARTUP?
Walk around the machine to check for leaks, loose components, or damage; verify fluid levels (engine oil, hydraulic oil, coolant); inspect tire pressure or track tension; check for dashboard warnings.
6. ABNORMAL TIRE WEAR?
Check if tire pressure is below standard, chassis alignment is incorrect, or driving habits are poor (e.g., sharp turns, dragging brakes).
