• Underground high-voltage XLPE armored cables are supplied on massive wooden or steel reels weighing between 5 and 20 metric tons. Improper drum lifting or unstable payoff setups present severe tip-over hazards and can crush cable layers.

Heavy-duty cable drum trailers and hydraulic lifting jacks must meet the following technical criteria:

1. Hydraulic Drum Jack Lifting Mechanism: Dual independent hydraulic cylinders with mechanical safety locking pins allow a single operator to lift heavy cable drums evenly off the ground without crane assistance.

2. Integrated Disc/Hydraulic Braking System: The drum trailer or stand must include an adjustable mechanical or hydraulic payout brake to prevent reel over-spin during winch stops, avoiding cable slack and tangling.

3. High-Strength Bearing Spindle Bars: Spindle shafts must be engineered from high-grade alloy steel capable of supporting concentrated point loads without bending. Spindle cones and locking collars must secure the drum centrally on the axle.

4. All-Terrain Braking & Towing Compliance: Heavy transport trailers must feature air or hydraulic brakes, shock-absorbing suspension, and highway-compliant lighting for safe towing over rough site access roads.

Ningbo Changshi manufactures custom all-terrain hydraulic cable drum trailers and portable hydraulic drum jacks rated from 3 tons to 25 tons, designed for maximum stability during highway transport and high-tension cable payout.
