Detail Information
Instruction:
Chassis:
The wet concrete spraying truck cab is centered, the wheelbase is only 2.4 meters. The front axle has a swinging suspension. It has good driving performance with wide tires. The approach angle and departure angle can reach 25°, and the ground clearance is up to 0.4 meters. The whole vehicle is powered by Yuchai 62.5KW diesel EFI engine. The walking system adopts hydrostatic drive system. The steering system adopts multi-wheel steering control system, which has various steering modes, such as front wheel steering, four-wheel steering, crab walking steering and so on. The vehicle can be flexibly turned and driven in a small space.
Features:
Boom:
The shotcrete pump boom adopts a folding + swivel + telescopic structure. The boom manipulator has seven-axis freedom. It can perform precise head-pointing spraying and Th-like brushing spraying in all directions. After fully retracted and then rotated, the boom slewing radius is only 1.8m, which enables the boom to perform 360° unobstructed rotation in a small space. The maximum front spraying distance can reach 8m when full extension, the maximum spraying height can reach 10m, and the maximum spraying width can be up to 18m and the maximum spraying depth is up to 4.5m.
As length 5m, width 1.85m, height 2.6m concrete wet spray trolley, it can meet 3M×3M - 12M × 8M (W×H) medium and small section tunnels, roadways, slopes, culverts, mines and other concrete spray anchor support operations, the vehicle has some features such as flexibility, fast concrete spraying, low rebound, simple operation, labor saving and so on. The equipment is a flexible, reliable and cost-effective concrete wet spray manipulator.
Areas of application:
The SAINTYOL DAWIN Machinery wet concrete shotcrete pump are based on technical pioneer achievements. They keep researching and developing new technology - and have been doing so for many years!They are the national initiative equipment for fine stone concrete conveying and won two national patents.
·Fine stone concrete conveying
·Floor heating construction
·Tunnel and underground construction
·Mortar conveying
·Used as spray pump when Installed with incidental spraying equipment, for concrete, mortar, refractory material and green soil spraying
QKSP-20 wet concrete shotcrete pumpare applied for high-rise conveying, railway, tunnel, bridge construction and special applications, hydraulic power, mining and national defense.

Main Parts:
Swing Arm
Diesel engine
Brand: Tianjin LOVOL/ Yuchai /Weichai/Cummins
Diesel engine adopts Tianjin LOVOL or Yuchai or Weichai or Cummins as custom request, which has low energy consumption and high efficiency
Pumping System
Concrete pump pumping system is the core technologies of Saintyol DAWIN Machinery,
DN140mm, 180mm, 200mm and 230mm large diameter cylinder, absorb good, pumping large displacement.
Main Oil Pump
Main oil pump adopts joint venture brand constant power variable plunger pump. Constant power control is effective to prevent the electromotor or diesel engine form overloading. It can withstand higher pressure and load than ordinary gear pump.
Cordless Remote Control
Remote control adopts domestic well-known brands, remote control distance, strong signal, no dropped calls, serial number phenomenon.The electrical components are all made by international famous brands such as Schneider, Siemens.
Cooling System
Hydraulic pipe joints
Hose joints: American Eaton; Pipeline: Original from Italy.
A set of these supported by Eaton.
S Valve
Brand: joint venture brand
Original: Germany
S tube valves are cast into shape with austenitic manganese steel, the quick wearing surface is welded with wear-resistant material, has dual advantages of anti-high pressure and anti-wearing.
