Carrier

▪ Sany manufactured two-axle carrier, 4 x 2 x 2 types, stage IV/stage V of National emission standard engine, 8-speed gearbox.

Crane Frame

▪ Designed and manufactured by Sany. Introducing the rectangle section structure. Rigidity is enhanced by 20%.

Outrigger

▪ H-type outrigger beams with 4-point support. Using fine grained, ▪ high strength steel, the fully-hydraulic outriggers offer easy ▪ operation. The transverse and longitudinal span of 5.54m x4.85m ▪ provides excellent stability.

Turntable Structure

▪ Manufactured with high-strength steel, the box-type frame structure enhances rigidity by 30%. The swing bearing is exceptionally strong and smooth. Its large diameter contributes to enhanced stability.

Hydraulic System

▪ Main Winch is equipped with fixed displacement motor, high efficiency for working; The max speed of winch and auxiliary of single line is 105m/min, lifting efficiency is leading in the industry. Using the new slewing system, the start and control of slewing will be more stable and micro moving will be more excellent.

Operating system

▪ With overall wide cab, it is of broad vision and safe and conformable driving; The cab may choose to be equipped with sleeping berth, with neither work nor rest neglected.

Lifting System

▪ The maximum length of boom is 30m, maximum lifting moment is 480kN·m , maximum lifting height is 30.5m, The span of outrigger is 5.54m×4.85m,which are both leading in the lifting industry.

Luffing System

▪ A “power up”, “gravity lower” boom luffing system is adopted for enhanced precision and control while lowering the boom with a load.

Slewing System

▪ It can swing for 360 angle, the maximum swing speed is 2r/min and ensure moving stable , system reliable and breaking smooth.

Operator's Cab

▪ With overall wide cab, it is of broad vision and safe and conformable driving; The cab may choose to be equipped with sleeping berth, with neither work nor rest neglected.

Safety Devices

▪ Equipped with a Sany manufactured, high precision load moment indicator system, anti-two block system, hoist drum third wrap protection, programmable boom height limiter, counterbalance

▪ valves on boom and hoists. All load bearing hydraulic cylinders are equipped with lock valves.

Boom Structure

▪ 4 section boom 9.3m – 30 length,. Made of high strength welded structural steel with a U-type cross section. The full power, fully synchronized boom utilizes one hydraulic cylinders along with extend and retract wire ropes.

Electrical System

▪ Equipped with two 12 volt maintenance free batteries and a battery disconnect switch. Communication between the carrier and superstructure are via CAN bus.
