Sany STC1000T6 Load Chart PDF + Specifications

The SANY STC1000T6 is a 100-tonne truck crane developed around a four-axle road-going carrier and a long six-section telescopic boom. Its design emphasizes strong long-boom lifting performance, a relatively compact 2.8 m-wide chassis, high road mobility and modern electro-hydraulic controls. The crane is intended for construction, industrial installation, infrastructure maintenance and other lifting applications where road travel between jobs is important.

Lifting Capacity and Main Boom

Maximum rated lifting capacity is 100 tonnes, with a minimum rated working radius of 2.5 m. The crane uses a six-section oval-shaped telescopic boom fabricated from high-strength steel. The basic boom measures 12.9 m, while the fully extended boom reaches 60 m.

Maximum lifting moment is 3,557.5 kN·m on the basic boom and 2,254 kN·m on the fully extended boom. In the appropriate full-boom configuration, the 60 m boom can lift up to 13.5 tonnes, giving the STC1000T6 comparatively strong performance at long boom lengths.

The telescoping system uses single-cylinder pinning with electro-hydraulic control, allowing automatic extension and locking of the boom sections. Mechanical and hydraulic interlocks between the cylinder pins and boom pins are incorporated to maintain safe and reliable telescoping. Full boom extension takes approximately 480 seconds, while full retraction takes around 460 seconds.

Jib and Maximum Reach

For additional height and outreach, the STC1000T6 can be fitted with a 17.5 m jib. Jib offset angles are 0°, 15° and 30°, allowing the operator to adapt the working geometry to different lifting conditions.

An optional 9.5 m boom extension can also be added. With the 60 m main boom, boom extension and jib installed, the maximum total boom system length reaches approximately 87 m, with a corresponding maximum lifting height of about 87 m. Maximum lifting moment with the fully extended boom and jib is approximately 905.5 kN·m, reducing to around 564.5 kN·m with the additional boom extension and jib combination.

Hoisting Performance

The crane is equipped with main and auxiliary winches, both using hydraulic drives and dedicated braking systems. Maximum single-line speed for both winches is approximately 130 m/min.

The main winch uses approximately 275 m of 20 mm wire rope, while the auxiliary winch carries around 185 m of 20 mm rope. Maximum single-line pull is approximately 7.5 tonnes for each winch.

Available hook blocks cover a range of duties. A 50-tonne double-eye hook block and a 7.5-tonne single-line hook are standard, while optional equipment includes 55, 75, 90 and 100 tonne hook blocks, together with a 75-tonne double-eye hook. The 100-tonne hook block uses seven sheaves and fourteen-part reeving.

Slewing and Boom Elevation

The upperstructure provides continuous 360° slewing with a maximum speed of approximately 1.7 rpm. The slewing system incorporates a buffer valve and free-swing function, giving smooth starting and stopping together with good low-speed control.

Boom elevation ranges from approximately -1° to +80°. Full boom raising takes around 65 seconds, while lowering takes approximately 90 seconds. The luffing system uses a single cylinder and relies partly on gravity-assisted lowering to reduce energy consumption.

Counterweight System

The STC1000T6 uses a modular counterweight system with a maximum of 30.2 tonnes. Available combinations include 0, 2.2, 7.2, 8.2, 13.2, 19.2, 25.2 and 30.2 tonnes.

Counterweight installation and removal can be controlled remotely. The carrier is also designed so that the crane can move short distances at low speed with up to 19.2 tonnes of counterweight installed, improving efficiency when repositioning around large jobsites.

Outrigger System

The crane uses four H-type hydraulic outriggers with a maximum longitudinal and transverse span of approximately 8.0 × 6.53 m. The beams telescope hydraulically and the vertical jacks are protected by two-way holding valves.

The outrigger arrangement combines a relatively low-mounted front support structure with a high-strength chassis frame, improving both stability and access around the carrier.

Four-Axle Carrier

The STC1000T6 is mounted on a four-axle carrier with an 8×4×8 wheel configuration. All four axles are steerable, while two axles are driven. This arrangement gives the crane relatively good manoeuvrability for a 100-tonne truck crane.

Overall length is approximately 14.995 m, width 2.80 m and height 3.95 m. Gross vehicle weight is about 47 tonnes in the specified transport condition. Minimum turning radius is approximately 10 m, while the boom-tip turning radius is about 15 m. Ground clearance is 430 mm, with an approach angle of 18° and departure angle of 13°.

Carrier Engine and Transmission

Power is supplied by a Dongfeng Cummins ISLe375 30 inline six-cylinder turbocharged and intercooled diesel engine. The engine produces 275 kW at 2,100 rpm and maximum torque of 1,550 Nm at 1,200 rpm.

The engine complies with Euro III emissions requirements and is coupled to a 10-speed manual transmission with ten forward and two reverse gears. Fuel capacity is approximately 450 litres.

Maximum road speed is approximately 80 km/h, while maximum gradeability is about 45%. Published fuel consumption is around 45 litres per 100 km under the stated conditions.

Suspension, Steering and Braking

The front axle uses independent leaf-spring suspension, while the rear uses a balanced oscillating leaf-spring arrangement. The chassis uses heavy-duty axles with differential locks to improve traction on difficult ground.

All four axles are mechanically steered with hydraulic assistance. The braking system includes service, parking, emergency and auxiliary braking. Air-servo service brakes are fitted, with large drum brakes on the front axle to improve braking torque and thermal performance.

Hydraulic and Control Systems

The crane uses a double-pump intelligent flow-distribution system. Boom luffing operates independently, while telescoping can combine pump flow to improve working speed. SANY states that this arrangement improves combined-motion stability by more than 50%, while the electronic control system can reduce energy consumption and improve heavy-load operating efficiency.

The hoist operates on a closed hydraulic circuit, while the boom telescoping and luffing systems use open circuits with multiple pressure stages. This allows different functions to operate at pressure levels matched to the task, improving both control and efficiency.

Operator Cab

The crane operator works from a dedicated upper cab that can tilt upward by 20° for improved visibility during high lifts. The cab includes a panoramic skylight, adjustable seat, touchscreen display, heating and air conditioning.

The operator interface combines the main controls and display information, while multiple camera views can be shown on the screen to improve awareness around the machine.

Safety and Telematics

Safety equipment includes an electronic load moment indicator, hydraulic balance and relief valves, anti-two-block protection on both boom and jib, an anemometer at the boom head, boom-length and angle sensors, and pressure sensors.

The system can automatically restrict hazardous crane movements and provide audible warnings when operating limits are approached. SANY specifies lifting-load indication accuracy of approximately ±3% after calibration.

The crane also comes with ROOTCLOUD T-AMS Pro / MachineLink+ telematics, providing functions such as GPS tracking, machine-status monitoring, maintenance management, electronic geofencing, alarm management, fuel-use monitoring and operator management.

Overall Assessment

The SANY STC1000T6 is a well-equipped 100-tonne, four-axle truck crane combining a 60 m six-section telescopic boom, 17.5 m jib, optional 9.5 m boom extension, 30.2-tonne counterweight system and 80 km/h road speed. Its strong long-boom capacity, all-wheel steering, Cummins-powered carrier and modern electro-hydraulic control system make it suitable for construction, industrial lifting and infrastructure projects where both lifting performance and road mobility are important.
