Lifting and lowering device
Lifting and lowering device
Arborists frequently work at heights to perform maintenance tasks in the tree crowns or do sectional felling of trees. Therefore, these employees need lifting and lowering devices that will allow them to safely transport the equipment. PROTEKT offers the specialist TreeUP series that includes arborist products and devices for lowering tree parts, and lifting devices for arborists.

Lifting and lowering devices for arborists
As a manufacturer of safety equipment and systems for working at height, PROTEKT offers lifting and lowering devices with a port-a-wrap design that makes it possible to lower tree branches or trunks in a controlled and effortless manner. By tying the main rope around the pipe of the PROTEKT port-a-wrap devices, the worker minimizes the force necessary to hold the tree parts, at the same time controlling the speed of lowering. There are several devices for lowering trees in our offer. Depending on the model, they're characterized by:
- durability - made of galvanized or stainless steel;
- compact dimensions and relatively low weight - 1.92-7.3kg;
- minimum breaking load - 50 or 150kN;
- permissible working load - 0 or 30 kN;
- working rope with diameter of 10-14mm or 10-20mm;
- maximum tree diameter - from 1.2m (for AX 500 belt).
The Physics of Heavy Rigging
Removing large sections of timber generates massive kinetic forces that no ground crew can absorb through manual grip alone. Port-a-wraps solve this problem by routing the rigging rope around a steel cylinder, using friction to convert the kinetic energy of the falling timber into heat. This progressive absorption prevents violent shock loads from transferring to the ground worker or the anchor point. By adjusting the number of rope wraps, a single technician can safely manage the controlled descent of a heavy limb that would otherwise be physically impossible to handle.
Performance in High-Stakes Dismantling
The practical value of a well-engineered lowering device is most obvious during high-stakes dismantling over occupied properties. Galvanised steel construction ensures the device handles repeated high-load stress and year-round outdoor conditions without developing rough surfaces that could damage the rigging rope. Arborists running manual trunk-mounted winches alongside these devices note how smoothly they can lift timber over obstacles before beginning the descent. To ensure the complete system operates safely within its rated limits, these lowering devices must be paired with appropriately rated high-tensile rigging ropes from the safety equipment for arborists category.
Lifting devices for arborists
PROTEKT is a supplier of specialist lifting and lowering devices for arborists such as a durable manual winch attached to the tree trunk. This equipment protects the bark against damage, and enables precise and safe vertical transport of tree parts, using special runners. The equipment is characterized by a high maximum working load (13kN) and a minimum breaking force (65kN).
In our offer you can find also climbing spikes and full body harnesses.
