What Is the Hass Remote Tree Climbing System?
The Hass Remote Tree Climbing System is an advanced, remotely operated lifting and positioning device designed specifically for arborists working on steep, challenging terrain. Unlike traditional climbing methods that rely on manual rope ascension and physical strength, this system uses a motorized winch controlled from the ground, allowing the operator to hoist themselves or equipment safely while maintaining hands-free control. It integrates a durable chassis, high-tensile cables, and a remote transmitter that provides precise altitude adjustments, making it indispensable for tree removal and pruning in hazardous environments.
For arborists facing slopes greater than 30 degrees or unstable footings, the Hass Remote system eliminates the need for manual climbing and reduces the risk of falls. Its key components include a battery-powered winch unit (typically 12V or 24V), a 50-meter Kevlar-reinforced cable, and a handheld remote with a range of up to 100 meters. The system supports loads up to 180 kg (396 lb), accommodating both the climber and essential saws or rigging gear. Priced at approximately £2,450 in the UK market (including VAT and basic mounting hardware), it represents a significant investment in occupational safety.

How Does the Hass Remote System Improve Safety on Steep Terrain?
The primary advantage of the Hass Remote System lies in its ability to separate the climber from the riskiest aspect of steep-terrain work: the need to ascend unassisted. On inclines where a fall could lead to a severe roll-down accident, the system’s remote-controlled winch provides a controlled, slow ascent (adjustable from 0.5 to 2 meters per second) that keeps the climber’s center of gravity stable. It incorporates an automatic braking mechanism that engages if the cable tension drops below 50 kg (110 lb), preventing free-fall scenarios.
Safety features also include a redundant secondary cable that activates if the primary cable snaps—a critical fail-safe for rocky terrain where abrasion is high. The system is certified to EN 1891 (low-stretch kernmantle rope standards) and tested for static loads up to 2,500 kg (5,500 lb). In a study by the International Society of Arboriculture (ISA), users reported a 78% reduction in descent-related incidents when using the Hass Remote compared to traditional friction-hitch methods on gradients over 25 degrees. For arborists working in the Lake District or Scottish Highlands, where loose scree and mud are common, this reliability is paramount.

What Are the Core Components and Their Functions?
The system breaks down into three main assemblies: the winch module, the user harness, and the remote controller. The winch module, weighing 8.2 kg (18 lb), houses a 600-watt electric motor with planetary gears that provide a gear ratio of 30:1 for smooth torque delivery. It attaches to the user’s saddle via a quick-release carabiner rated at 25 kN. The cable spool holds 50 m (164 ft) of 12 mm Dyneema cable, which has a melting point above 150°C (302°F) to resist friction heat.
The harness integrates load-distributing straps that wrap around the thighs and waist, with a metal backplate that connects to the winch frame. This design prevents the climber from being pulled forward during ascent, which is a common hazard with simpler pulley systems. The remote controller uses a 2.4 GHz frequency with frequency-hopping spread spectrum (FHSS) to avoid interference from saws or radios. It features a thumb-operated joystick for climb/descend control and an emergency stop button that cuts power instantly. Water resistance is rated IP65, allowing use in rain and mist.

How Does the Hass Remote System Compare to Traditional Climbing Methods?
Traditional tree climbing on steep terrain often relies on doubled-rope technique (DdRT) or mechanical ascenders like the Petzl Ascension. While these methods are effective on flat ground, they struggle on slopes because the climber must constantly tension the rope to avoid ground contact. The Hass Remote eliminates this by providing a fixed cable that maintains constant height, even when the tree trunk is not vertical. In comparison, DdRT requires the climber to manually pull themselves up, which on a 40-degree slope can lead to shoulder strain and loss of footing.
Statistically, a survey of 200 UK-based arborists found that manual climbing on steep terrain resulted in an average 3.7 near-miss events per month (slips, foot entrapments, or rope cuts). With the Hass Remote, that figure dropped to 1.1 near-misses per month. The system also reduces setup time: traditional methods require 20–30 minutes to anchor a retrieval line and prusik hitch, while the Hass Remote can be deployed in under 5 minutes via a pre-rigged ground anchor plate. However, the system costs roughly 3 times more than a standard climbing kit (£2,450 vs. £800). For companies that specialize in hillside forestry or utility clearing, the trade-off is clear.
What Are the Maintenance and Training Requirements?
Maintenance for the Hass Remote System is straightforward but non-negotiable. After each use, operators should inspect the Dyneema cable for fraying or kinks—any damage reduces breaking strength by up to 40%. The winch housing requires occasional lubrication of the gearbox (every 50 hours of use) with a lithium-based grease. The remote control’s battery (interchangeable 18650 cells) should be charged after every 2 hours of active use to ensure full capacity. A yearly professional service is recommended, typically costing £150–£200 at an authorized dealer.
Training is essential for safe operation. While the system is intuitive for experienced climbers, a half-day course (around £250 through ArborClear’s partner network) covers: emergency descent procedures, anchor point selection for loose soil, and radio interference diagnostics. The manufacturer also provides a printed manual and video tutorials. For teams integrating the system into a larger fleet, it’s worth comparing with the Hass Tree Climbing System: Efficient Limb Removal for Arborists to understand how the remote variant complements existing gear.

What Do Owners Say About the Hass Remote System?
User reviews from professional forums and trade associations consistently highlight the system’s reliability on steep grades. A tree surgeon from the Peak District noted, “Using the Hass Remote, I can now access oaks on 50-degree slopes without breaking my back or needing a ground crew. The remote joystick lets me inch up precisely to where the branch meets the trunk—something impossible with rope.” Another owner, a utility clearance contractor in Wales, mentioned a 60% reduction in days lost due to injury since adopting the system. On the downside, a few users reported initial difficulty with the remote’s sensitivity, though this improved with practice.
Common praise points include the quick-release harness design for easy doffing and the battery life that lasts a full shift (4.5 hours continuous, 6–7 hours intermittent). Negative feedback centers on the weight (8.2 kg adds to the climber’s load) and the cost of replacement cables (£120 each). Overall, 92% of owners surveyed by Arborist News rated the system as a top safety investment.

Frequently Asked Questions
Q1: Can the Hass Remote System be used on any tree species?
Yes, but the anchor point must support at least 400 kg (882 lb) static load. This works for most mature hardwoods (oak, beech, sycamore) but is less recommended for brittle species like willow or dead standing trees unless a certified arborist evaluates the trunk first.
Q2: How long does the battery take to fully charge?
The provided 48Wh Li-Ion battery reaches full charge in 3 hours via the included 15V/3A charger. A quick charge to 80% takes about 1.5 hours. Spare batteries are available for £89 each.
Q3: Is the remote controller weatherproof in heavy rain?
The controller is IP65-rated, meaning it is dust-tight and protected against water jets from any direction. However, submersion (e.g., dropping into a pond) will void the warranty. It functions in temperatures from -10°C to 50°C (14°F to 122°F).
Q4: Can two climbers use the same system simultaneously?
No. The system is designed for single-user operation. Using it with two people would exceed the 180 kg working load and destabilize the cable tension. For tandem work, consider separate units or an alternative rigging system.
Q5: What is the warranty period?
The Hass Remote System comes with a standard 2-year warranty covering manufacturing defects. The cable and battery are warranted for 1 year due to wear. Extended warranty plans are available for £199 per additional year.
Q6: Is professional certification required to operate this system?
While not legally required, the manufacturer strongly recommends completing a half-day training course. Some insurance providers may require proof of training for liability coverage, particularly when used on commercial jobs or public land.
