The five-section infinitely variable speed control RZ expansible
boom system , produced by all adopting imported 900Mpa high-strength
steel plate, has the features of speedy expanding, being capable
of construction in narrow building sites, and each arm-section capable
of separate operation to avoid any dead corner in construction.
☆ The closed hydraulic system of electric proportional constant
power variable capacity and pull-power PTO, without the frequent
change valve block in main oil duct, can work smoothly with pressure
loss smaller and can change with no impact compared with open
circuit.
☆ Big-diameter transport cylinder has a good suction ability
of material and a large pumping capacity.
☆ The pump delivery ability has infinitely variable control function
to be adjustable to various output quantities’ demands.
☆ The aggregate carrying pipe can take position accurately by
control handle with remote-control device that is light and easy
to carry.
☆ Fluid pressure has the function of overloading protection.
When pipe being plugged, the main pump output returns to zero
automatically and the motor output gets smaller, which prolongs
the motor’s using life significantly.
☆ Pump delivery change is hydraulic flexible change. The pumped-out
concrete flow and pressure are smooth, which significantly reduce
the aggregate carrying pipe’s vibration during working. The tail
pipe quivers little, which can both cast precisely and improve
the carrying pipe’s using life.
☆ Adopt VOLVO or CHDT’s HOVO chassis which reaches the European
Ⅱ environmental standard.
☆ Import Germany top brand transfer case and hydraulic parts.
