    The TH2040 is a heavy duty impact block style lowering pulley, available in a choice of anodised colour finishes

    With swivelling side plates TH2040 can be easily installed mid line, and a simple ½ turn on the thumb screw secures the plates closed. The plates are forged aluminium for strength and impact absorption, and finished round and smooth to avoid rope damage.

    The block features a handy hollow bore on the large lower sheave which can be utilised for a secondary positioning line to rig the pulley away from the trunk, or for a speed line system

    With heavy duty stainless steel bearings, the large sheave can take rope up to 18mm diameter and has a working load limit of 20kN.

    In dismantling of large stems, the impact pulley is typically installed with a round sling or whoopee sling, just below the section being cut.

    Please remember, rigging of loads for dismantling trees is a dangerous operation where many unseen factors affect the behaviour of falling loads.

    Rigging should only be undertaken by trained personnel.
  • ISC Large Aluminium Rigging Pulley 70kN, 20mm Rope
    Fully modular design allows pulleys to be fitted with bushings or bearings bushings use mos2 silicone impregnation for improved wear resistance, bearing systems uses sealed roller bearings for reduced friction. All pulleys are laser marked with obligatory details and individual serial numbers. Circumferential markings around axle rivets denote bushing or bearing. Axles are riveted rather than bolted to comply with the European standard and so that they are fully tamper proof and totally impossible to unscrew during use. Becket eyes allow a karabiner to be rotated fully. Fully load rated beckets.
