80 Ton Xct80 Telescopic Boom Truck Crane

Product Introduction

The main boom features a U-shaped cross-section design, delivering exceptional lifting performance with a maximum basic boom lifting moment of 3352 kN·m or higher. Its K-type outrigger structure provides an ultra-wide span, effectively ensuring overall machine stability during operations.

Product Advantage

1. Super lifting performance

6-section boom of 50m with U-type profile is the longest of the same class in the industry; the max. The performance is 20~30% higher than that of the competitors. The telescoping mode is updated from sequential telescoping to random telescoping. New single-cylinder pinning telescoping system brings higher telescoping reliability.

2. New energy-saving hydraulic system

The min. stable slewing speed is 0.1°/s. The min. stable lifting speed (drum) is 2.5m/min. Precise and safe lifting movements can be realized.

Independent cooling technology of the hydraulic motor can make the thermal balance temperature of the hydraulic system below 80ºC. It can work normally in the high temperature environment and thus the hoisting operation is safe and reliable.

3. Drive train

Heavy truck group MAN engine, rated power 268kw, max torque 1800N.m Shangchai diesel engine, rated power 251kw, max torque 1600N.m

4. Low-speed large-torque power drive system

Resulting in perfect combination of high-power performance and low fuel consumption, i.e.12% reduction in fuel consumption for driving, 15% for operation, and 15% improvement in power performance.

Technical Parameters

Product Uses

1. Urban Construction and Municipal Engineering

The XCT80 is ideally suited for space-constrained operations such as urban construction sites, municipal pipeline networks, and renovation of older residential communities. Its optional “all-wheel steering” chassis achieves a minimum turning radius of just 20 meters, enabling multiple maneuvering modes including crab steering. This exceptional agility significantly minimizes disruption to daily life and traffic flow.

2. Transportation Hubs and Large-Scale Infrastructure

This crane is widely deployed in major infrastructure projects like ports, bridges, and highways. Its robust lifting capabilities efficiently handle critical tasks such as installing large precast beams and steel structures.

3. Industrial Sites and Energy Projects

The XCT80 is the ideal choice for installing and maintaining large equipment in petrochemical plants, mines, oilfields, and other industrial facilities. Its precise control and stability ensure safe, efficient hoisting and positioning of heavy equipment like large reactors and tanks.

4. Wind Turbine Installation Support Operations

At domestic wind farm sites installing turbines under 3MW, the XCT80 serves as a common auxiliary hoisting vehicle, earning its reputation as the “standard configuration for wind power support.” It handles tasks like tower section lifting, rotor tail handling, and transporting wind turbine arms and counterweights for main cranes. Its rapid boom extension speed and strong adaptability to mountainous terrain make it highly suitable for such operations.

5. Special Terrain and Heavy-Load Relocation

For uneven construction sites like mines and oilfields, its optional chassis configuration—dual front-axle steering with dual rear-axle tires—provides greater ground contact area and enhanced load-carrying capacity. During short-distance relocations, it can carry 24.6 tons of counterweight, eliminating trailer costs for safe and efficient operations.

Product Operate Guide

Before operating the XCT80, fully extend the outriggers and ensure the ground is solid and level. Maintain the crane in a level position at all times during operation, and strictly prohibit any overload operations. Extend and retract the boom steadily and slowly, paying particular attention to maintaining a safe distance from surrounding obstacles. Rotate the crane slowly and at a constant speed, avoiding abrupt stops or turns. Regularly inspect the wire rope for wear. After completing operations, retract the boom, secure the hook, and maintain daily equipment maintenance records.

FAQ

1. ARE THERE DUST MARKS ON THE INNER WALL OF THE AIR FILTER HOUSING?

The filter element seal is compromised, or the housing clips are not fully engaged, allowing unfiltered air to bypass into the engine.

2. ARE MULTIPLE TEETH ON THE SLEWING RING SHOWING ABNORMAL WEAR?

Minor deformation in the slewing motor mounting surface or the slewing ring itself causes poor meshing.

3. ELECTRICAL HUMMING IN THE RADIO OR AUDIO SYSTEM DURING OPERATION?

Electromagnetic interference caused by worn generator brushes or aged rectifier diodes. Inspect the generator and filter circuitry.

4. FREQUENT DAMAGE TO PRESSURE TEST FITTINGS INSTALLED ON THE PRESSURE PORT?

Failure to slowly relieve pressure after testing causes high-pressure oil to instantly impact and damage the ball valve. Resulting from improper operation or poor-quality fittings.

5. ALL MOVEMENTS ARE EXTREMELY SLOW AT IDLE SPEED, BUT NORMAL WHEN THROTTLE IS INCREASED?

Normal behavior. At idle, the engine outputs low power and the hydraulic pump delivers low flow to reduce fuel consumption and noise.

6. SENSOR SIGNAL VOLTAGE OCCASIONALLY DROPS TO ZERO DURING OPERATION?

Loose connection in the sensor power supply circuit causes momentary disconnection during equipment vibration.
