भीमनिःस्वना emitting frightening sounds, रथिनः charioteers, कालान्तकोपमैः deadly like the Lord of death at the time of universal dissolution, शरैः arrows, सहसा forcibly, नर्दताम् roaring, वानरेन्द्राणाम् Vanara leaders, शिरांसि heads, जह्रुः severed.

The Rakshasa charioteers severed the roaring Vanara leaders forcibly with their arrows emitting frightening sounds. They were like the Lord of Death at universal dissolution.
