★ Description of the lifting weight in the above lifting performance table

1) The value indicated by the rated lifting capacity in the table is the maximum lifting capacity that the crane can guarantee on a flat and solid ground. The starting amount does not exceed 75% of the tipping load;

2) The rated lifting weight in the table includes the weight of the hook and spreader;

3) The working range in the table is the actual value including the deformation amount of the boom, so the lifting work must be carried out based on the working range;

4) 75% of the tipping load considering wind 6, i.e. pressure of 125N / m allows up crane legs still fight when six jobs wind, and prohibits operation of the tire with the carrier tape job.

 

System structure description

Boom

The five-section sequence plus the synchronous telescopic 8-sided section boom. The telescopic system consists of two telescopic cylinders and two sets of thick cables. One of the cylinders telescopes two arms, the other cylinder retracts three arms, and the three, four, and five arms are synchronously stretched by the thick cable. The cross section of the telescopic arm is supported by a nylon slider.

Basic arm length     – 10.23m

Full extension of the main arm     – 37m

Main arm full extension speed – 110s

Pulley diameter     – 393mm

Boom angle of change – 5 ° ~ 78 °

Boom speed – 5 ° ~ 78 °, 80s

2. jib

The two jibs are placed on the right side of the main arm, swinging out, rectangular section, truss structure, and the arm head is equipped with a single pulley.

Length         – 9.8~16m

Angle         – 0°, 30°

3. Swing

The planetary reducer driven by the hydraulic axial piston motor realizes continuous 360° full rotation and has a normally closed rotary brake, which can be freely slid or locked by the control button.

Swing speed: 0~2 (r/min)

4. Main hoist

The hydraulic axial piston motor drives the reel to rotate through the planetary reducer for heavy lifting. It is equipped with a normally closed brake and a balancing valve.

Roll diameter × width: 0.458m × 0.71m

Wire rope diameter × length: 20mm × 210m

Single rope tension ( layer 4): 84.8KN

5. Deputy hoisting

The hydraulic axial piston motor drives the reel to rotate through the planetary reducer for heavy lifting. It is equipped with a normally closed brake and a balancing valve.

Roll diameter × width: 0.4m × 0.646m

Wire rope diameter × length: 18mm × 130m

Single rope tension ( layer 4): 52KN

6. Wire rope

Main coil wire rope   – 20-4VX39S+5FC-1870

Length         – 210m

Secondary coil wire rope (not rotating) – 18-NAT7X35W-1870

Length         – 130m

7. Hook

Main hook       – 70 tons hook (with 6 pulleys and safety pin)

Secondary hook       – 5 ton hook (with safety pin and weight hook)

 

8. Hydraulic system

Pump

The power components are two sets of two gear pumps, 80+40 and 80+08 respectively. The lifting function is powered by two 80+80 pumps; the leg function, steering function, luffing function and telescopic function are powered by 80 pumps in the 80+40 two-stage pump; the rotary function and the brake function are provided by 40 pumps. Power is supplied according to different job requirements, and the control function is powered by the 08 pump.

Control valve

Under the action of the pilot pressure, each action is controlled by a solenoid valve and a hydraulic valve.

tank

The fuel tank has a capacity of 1010 liters, and the fuel tank is equipped with a liquid level gauge, which can be used as the oil level and hydraulic oil temperature.

filter

The self-sealing suction filter outside the box is equipped with a self-sealing valve, a filter pollution transmitter and an oil bypass valve, which improves the reliability of the hydraulic system. It adopts a straight-back self-sealing magnetic oil return filter with permanent magnets, bypass valves and check valves to protect the filter and system from normal operation.

heat sink

The air-cooled unit is a blow-drying structure.

Emergency pump

When the vehicle fails, the emergency pump is used to power the steering system.

9. Cab and internal control

The driving and working functions of the crane can be performed from the cab mounted on the side of the turntable. The overall design of the cab is steel structure, which can be used for one person, sliding doors to enter and exit, and side safety glass windows. The cab is made of gemstone green safety glass and the front windshield is laminated curved glass. Equipped with electric wiper and washer.A mesh protective cover is installed on the outer side of the right sliding window, and a glass top window with a wiper and a safety fence is installed on the top. The integrated display and control console, the bottom plate is equipped with an electronic accelerator pedal, the rotary brake pedal, the seat can be adjusted up and down, the seat is on both sides of the hydraulic pilot handle armrest box.The cab is equipped with air conditioning.

Engine start /stop, display, gear selector switch, parking brake switch, steering mode selector switch, pilot switch, boom telescopic selector switch, main (sub) winch selector switch, control panel, outrigger work selector switch, Free slip (lock) switch. Torque converter oil temperature, engine water temperature, brake pressure, fuel tank liquid level display, speedometer, odometer, tachometer, engine fault diagnosis, reversing alarm, low oil pressure / high water temperature alarm, force limiter over limit alarm Device (visible). Arm warning light, rotary warning light, safety image monitoring system.

The vehicle uses a fully automatic torque limiter

l  Controller port status display function

l  boom position display

l  swivel angle

l  main arm angle, main arm length, jib mounting angle, jib length, lifting range, rated lifting capacity, actual lifting weight, lifting height

l The  ratio of actual bearing torque to rated bearing torque is displayed

l  Allowable bearers
