1.4-section M-shaped boom, with fast expansion speed;
2.X-H shaped outrigger makes the pump suitable for working at narrow site;
3.Computer controlled energy saving technique achieves optimal match between engine power and pump load, saving 20% oil consumption on average;
4.Pump displacement is up to 120m³/h, with stepless regulation which can meet requirements of different working conditions;
5.Electrohydraulic coupling controlled boom vibration absorbing technique greatly prolongs service life of the boom;
6.The original SYMC special controller contributes to much more stable operation of the system;
7.The adoption of the anti-tilting control technology improves intelligent level of the pump and enhances its safety performance;
8.Electrohydraulic buffer, differential pressure induction, open loop hydraulic system full-hydraulic directional control provides for small directional control impact and high reliability;
9.Automatic retraction of concrete piston makes it easier to check or replace the piston;
10.Automatic switch-over between high and low pressure improves pumping applicability;
11.Functional parameters are displayed by color graphics dynamically; fault type is prompted; multiple automatic protections are provided.
