DMM Eccentric Hitchclimber Pulley - Green

DMM Eccentric Hitchclimber Pulley - Green

The DMM Eccentric Hitchclimber Pulley - Green is a refined evolution of the classic Hitch Climber design, developed to improve efficiency, rope control, and overall system organisation for professional arborists. Engineered for friction hitch work positioning systems, it supports both moving and stationary rope techniques while advancing the hitch earlier and more predictably. Its distinctive eccentric geometry and optimised rope guidance help climbers manage slack more effectively, contributing to smoother movement and reduced effort during ascent and repositioning.

Advanced geometry for improved hitch tending

The eccentric profile of this pulley is designed to advance friction hitches earlier in the system cycle, improving responsiveness during climbing. Integrated pushing plates work with the rope path to encourage consistent hitch engagement, while optimised fairlead flares guide the rope smoothly towards the 42 mm sheave. This geometry supports better slack handling and helps maintain efficiency when transitioning between movements, particularly during frequent positioning adjustments.

Efficient rope handling with organised connections

A three hole rig plate layout allows connectors and textile components to be arranged neatly within the system, helping reduce clutter and improve alignment. This configuration supports off-centre hanging, which can reduce rope-to-pulley friction during use. Designed for rope diameters from 7 mm to 14 mm, the pulley balances compatibility with efficient handling, making it suitable for a wide range of professional climbing setups.

Precision construction for professional use

Hot forged and CNC machined aluminium side plates combine strength with weight efficiency, while a large diameter stainless steel axle assembly provides stiffness and durability. The efficient roller bearing supports smooth sheave rotation under load, contributing to predictable rope movement. With a minimum breaking strength of 32 kN, a working load limit of 6 kN, and a weight of 184 g, the pulley offers a strong yet refined solution for daily arborist work. Corrosion resistant and tamper proof assembly supports long-term reliability in demanding environments.
