Ask digging Heavy QUY1250 Hydraulic Crawler Crane
HC Engineering Machinery Network May 19 morning, ask dug Heavy Industrial Park groundbreaking ceremony of the new dig cum ask Hydraulic Crawler Crane Heavy QUY1250 new product development zone handover ceremony was held at the Fushun Shih. The following is Fu dug Heavy QUY1250 Hydraulic Crawler Crane Products.
Main features are as follows: Engine ? Cummins 6-cylinder water-cooled QSK23 diesel engine, power 641KW, rated speed 2100rpm, meet the EURO-2 emission standards.
Engine is equipped with air pre-filter, two-stage air filter, muffler, combined cooling, heat sink and fan development Cummins Engine Parts.
Transfer case through eight variable piston pump, 3 Gear Pump Power system to the system power.
Two 12-volt maintenance-free battery, 24 volt system and 75 amps AC Generator .
A 1300 liters diesel fuel tanks, installed in the turntable of the power station, in the cab of oil surface indicator.
Control system Electronic proportional control handle through the various procedures to control storage operations, including the diagnostic system. Color display and can operate safety torque controller. Working speed continuously variable transmission by controlling the rod position. Automatic Power Control to optimize the use of the engine output power. Use of Rexroth the company’s RC controller and monitor, import encoder Torque limiter And surveillance systems, data transfer between the bus with Can-Bus technology to improve the system reliability.
Hydraulic system With closed hydraulic system, mainly Bosch Rexroth hydraulic components. The main action alone control, energy saving, efficient, controllable. System design of the system pressure alarm device Filter Plug the alarm device. In order to reduce the fever, flushing the system set up oil installations.
Vehicle wear off with automatic hydraulic device, to achieve automatic control of vehicle dismantling and effective to reduce work intensity and improve efficiency. 1,500 liters
system Hydraulic oil Box, consider a core and hydraulic cooler. Each movement is equipped with hydraulic valve to protect the back pass set and vibration.
Raise hoist device Standard crane hoist with 2 upgrade, that is the main hoist winch Vice H1, raise hoist H2, while customers can improve matching tower hoist arm Vice H3.
Fence-type reel design, the variable hydraulic Motor Planetary gear unit through the closed to power and independence drive, Built-in lifting device reducer so compact, easy disassembly. All wire rope hoist with a spring brake, hydraulic brake spring multi-chip.
Luffing winch devices: Standard luffing crane with main W1, Vice-amplitude W2, from the device configuration with a super-ultra-amplitude volume from Yang devices W3.
Fence-type reel design, the variable hydraulic motor through planetary reduction unit confined to power and independence drive, Built-in speed reducer so compact lifting devices to facilitate disassembly. All wire rope hoist with a spring brake, hydraulic brake spring multi-chip.
Rotation system Rotating part of the closed hydraulic system with three motor through a closed oil bath powered planetary speed reduction device can turn 360 degrees. Slewing 3 m diameter three-roller plate volleyball rotation, rotation speed: 0 ~ 1.1rpm.
Weight ? Pressure off weight: 75 tons, 7 weight, 2 trays.
Weight after the host: lateral suspension weight, 290 tons, 22 weight, 2 trays.
Over from the weight: 450 tons, 36 weights, a tray.
Cab Fully enclosed steel frame design, interior background noise. Comfortable and spacious cabin with a large windshield glass and air-conditioning, roof windows, a variety of display devices and crane control devices, fire extinguishers, ventilation devices and CD player. Ergonomic handle of the driver seat and operations. Cab can be 20 degrees on the Yang and increase the operator’s arm lever control outlook. Video cameras installed to observe the work of winch, cab can be placed in front of supreme vehicles and reduce transport width.
Lower body parts Off by the body, the two beams, composed of two tracks. Body, beams and tracked by the hydraulic pin connection, to reduce the weight and width of the transport, installation and removal easy.
Body, and beams From high strength alloy steel welded box-type structure, has good bending and torsional properties.
Track device Track frame with high bending strength structural steel welding is made. Track plate by the heat treatment of high strength cast steel, conveyor width of 2000m, the tension level can be tracked tanks is regulated by adjusting the gasket, the desired degree of tension. Centralized lubrication system as standard.
Drive
Driver in the form of four-wheel drive, four variables tracked by the hydraulic motor through a sealed planetary gear reduction powered, spring-loaded normally closed hydraulic brake system. Continuously variable control of each track, smooth operation, maximum travel speed of 0-1.01Km / h, both independent, but also reverse walk.
