Libec Standard weight kit of 30kg/66lb

The product you are looking for is the Libec WEIGHT30 KIT (also designated as the Weight30 Standard Weight Kit).

This heavy-duty counterweight package is explicitly designed to balance professional production cranes and telescopic jib arms—specifically the Libec SWIFT JIB50, JB50, and JB40 platforms. When you mount high-end cinema or broadcast cameras to a jib, counterweights are vital to balance the physical fulcrum, enabling smooth, zero-gravity vertical jib sweeps and tilt arcs.

1. Hardware Distribution & Configuration

The WEIGHT30 KIT breaks down the total 30kg (66 lbs) bulk into a modular, split layout. This prevents operators from having to lift dangerous, singular massive blocks and allows you to precisely fine-tune your payload equilibrium:

• Two Symmetric Weight Sets: The kit is cleanly split into two mirrored 15kg (33 lbs) groupings.

• Component Breakdown per Set:

  • 2 x 5kg (11.0 lbs) rubber-coated weights

  • 2 x 2.5kg (5.5 lbs) rubber-coated weights

• Total Kit Inventory: You receive a total of four 5kg weights and four 2.5kg weights.

2. Production-Tier Design Features

• High-Traction Protective Rubber Coating: Unlike standard bare cast-iron gym weights that can scratch support paint, chip metal, or rust when exposed to moisture, Libec builds these with a thick, high-density rubber exterior shell. This dampens metallic clanging sounds on quiet film sets and prevents structural slippage on the weight bar.

• Sized for Broadcast Weight Bars: The interior mounting cutouts are explicitly machined to slide seamlessly onto the rear balance bars of the SWIFT JIB series, keeping the center of mass close to the control arm axis.

• Dual Heavy-Duty Transport Cases: Because moving 30kg of standalone blocks across location shoots is cumbersome, Libec includes two dedicated padded carrying bags in the box. Each case neatly holds one 15kg cluster, preserving your back and organizing your kit on production trucks.
