Five minutes of questions, three machine recommendations, one site service plan — from subdivision earthworks to bridge precast lifts.
Each card pairs the pain points we hear from contractors with a Zoomlion machine mix you can refine with an advisor.
Soft pads, utility trenches and frequent machine moves without oversizing iron for a small cut/fill balance.
20–30 t crawler excavator + tandem roller + compact loader for backfill and trench spoils.
Mat temperature, compaction force and night-shift noise limits dominate the paving train schedule.
Asphalt paver + material transfer vehicle + dual tandem rollers + asphalt distributor.
Feed size, jaw opening and discharge opening must match crusher throughput before haul trucks arrive.
Jaw + cone + screen line with excavators, rigid haulers and a drill jumbo for face development.
Single-span lifts of 80–150 t need clear load charts, outrigger mats and tandem-lift procedures.
250–650 t crawler crane + lifting beams + Zoomlion advisor support for ASME B30 style lift plans.
High-reach envelopes, dust suppression and shear selection decide whether the city allows daytime cycles.
High-reach excavator + hydraulic shear + dust-suppression bowser staged on the perimeter.
Rotary drilling torque, bit life and ventilation constraints limit how fast the face advances each shift.
Jumbo drill + bit kits + ventilation support equipment sized to drift cross-section.
A core industry dispute from procurement shortlists — we present both sides before recommending a Zoomlion package.
Lower ground pressure suits soft pads and deep digs; stability helps heavy breakout force cycles. Trade-off: trailer moves between paved urban blocks add cost and time.
Self-propelled road transfers cut lowboy dependency on city streets and frequent site hops. Trade-off: poorer flotation on mud and less stability for deep trench digs versus crawler undercarriage.
Limits we disclose: wheeled units are a poor fit for deep quarry faces; crawler units are overkill if your only work is short paved utility repairs under 5 km apart.
Answer these with your superintendent — then send the checklist with cubic meters or paving kilometers so we can lock a package.
Check items you already know — unchecked items become questions on our quote call.
Include site type, cubic meters or paving km, and whether crane lift plans are required.
