SANY TRUCK CRANe

Highly efficient, stable, energy-saving, and

adjustable hydraulic system

Hydraulic system load feedback and constant power control
is applied to provide strong lifting capacity and good micro-
mobility. Unique steering buffer design is adopted to ensure
stable braking operation.

Ultra long, super strong and highly sensitive

load lifting capacity

Four-section boom of high strength steel structure and optimized
U-shaped cross section reduces weight significantly with higher
safety rates. Jib mounting angles are 0°, 15°, and 30° which
ensures fast and convenient change-over between different
operating conditions so as to improving working efficiency of the
machine.

Safe, stable, advanced, and intelligent

electric control system

Self-developed controller SYMC specially for engineering
machinery is configured. The adoption of CAN-bus full-digital
network control technology ensures stable control signal, simple
harness, and high reliability. Timely feedback of data information
can achieve the monitoring of the overall working status in real-
time; the load moment limiter equipped with the comprehensive
intelligent protection system is used with accuracy within 3%
to provide a comprehensive logic and interlock control, thus
ensuring more safe and reliable operation.

INTRODUCTION

Quality Changes the World

Cab

■

It is made of anti-corrosion steel plate with ergonomic design such as full-coverage soften

interior, panoramic sunroof and, adjustable seats etc., and humanized design providing

more comfortable and relaxing operation experience. The display of load moment limiter

integrates main console and operation display system, which clearly show the data of all

operating superstructure conditions for lifting operation.

Hydraulic system

■

High-quality key hydraulic components such as main oil pump, rotary pump, main valve,

winch motor, and balancing parts etc. are adopted to achieve stable and reliable operation

of the hydraulic system. Superior operation performance is guaranteed by accurate

parameter matching.

■

Through the adoption of load sensitive variable displacement piston pump, pump

displacement can be adjusted in real-time, achieving high-precision ﬂ ow control with no

energy loss during operation.

■

Main valve has flow compensation and load feedback control function, enabling stable

and convenient control of single action and combined action under different operation

conditions

■

Winch adopts the electronically controlled variable motor to ensure high operation

efﬁ ciency. Max. single line speeds of winches is up to 130m/min.

■

Slewing system is equipped with the integrated slewing buffer valve to ensure more stable

starting and control of the slewing operation and excellent micro-mobility.

Control system

■

With fully security protection system, winches are equipped with over-roll out limiter and

height limiters to prevent over-rolling out and over-hoisting of steel rope, including tip-over

and limit angle protection.

■

Load moment limiter: The adoption of high intelligent load moment limiter system can

comprehensively protect lifting operation, ensuring accurate, stable and comfort operation.

Luffi ng system

■

Dead-weight lufﬁ ng provides more stable lufﬁ ng operation at low energy loss.

■

Lufﬁ ng angle: -2°~ 80°.

Telescopic system

■

Five-section boom is applied with basic boom length of 10.2m, full-extended boom length

of 31m,jib length of 8m and lifting height of fully extended boom length of 32m respectively.

Max. lifting height is 40m including jib. It is made of fine grain high-strength steel with

U-shaped cross section and with telescopic operation controlled independent by ylinder

rope.

Slewing system

■

360° rotation can be achieved with Max. slewing speed of 2.5r/min. Hydraulic controlled

proportional speed adjustment is applied to provide stable and reliable operation of the

system. Unique rotary buffer design ensures more stable braking.

Superstructure

Hoisting system

■

The adoption of pump and motor double variable speed control ensures high efﬁ ciency

and excellent energy saving functionality. With perfect combination of winch balance valve

and unique anti-slip technology, heavy load can lift and lower smoothly. Closed winch

brake and winch balance valve effectively prevent imbalance of the hook.

■

One main hook: 320Kg, one auxiliary hook: 90Kg, and the Max. lifting height are 25t and 5t.

Wire rope of winch: left-handed wire rope 16-35W×7-1960USZ 200m.

Safety system

■

Load moment limiter: Load moment limiter calculation system based on lifting load

mechanical model is established using an analytical mechanics method with rated lifting

accuracy up to ±3% through on-line non-load calibration, providing full protection to lifting

operation. In case of overload operation, system will automatically issue an alarm to provide

safety protection for manipulation.

■

Hydraulic system is configured with the balance valve, overflow valve and two-way

hydraulic lock etc. components, thus achieving stable and reliable operation of the

hydraulic system.

■

Winch is equipped with over roll-out limiter to prevent over rolling-out of wire rope.

■

Boom is equipped with height limiters respectively to prevent over-hoisting of wire rope.

■

Boom head is equipped with anemometer and press sensor to indicate the working

condition of whole crane in real-time, giving an alarm and cutting off the dangerous action

automatically.

Counterweight

■

Counterweight is 1800kg, no ﬂ exible counterweight.

The vice carrier frame

■

Designed and manufactured by SANY, anti-torsion box structure is welded by ﬁ ne-grain

high-strength steel plate, to provide strong load bearing capacity.

Outriggers

■

Four-point supporting of the H-shaped outriggers ensures easy operation and strong

stability with max. span up to 5.45m×6.2m. They are made of ﬁ ne-grain high-strength steel

sheet with horizontal single-cylinder rope line telescoping for outrigger. Vertical cylinder of

outrigger adopts bi- directional hydraulic locks to improve safety.
