The following are professional operating precautions for the precast concrete hollow core slab making machine (hollow concrete slab machine), covering safety, process and maintenance points, and are suitable for construction site management:
1. Safety preparation before construction
Foundation and track inspection
Track flatness error ≤3mm/10m (calibrated using a laser level)
Foundation bearing capacity must be ≥150kPa (soft soil layers must be compacted or replaced in advance)
Equipment safety device verification
Emergency stop button response test (power-off time <0.5 seconds)
Hydraulic system pressure valve verification (working pressure ≤25MPa)
Install anti-backward ratchet device (mandatory activation when slope >5°)
