Tractel - Tracbloc2 8FT Self Retracting Lifeline with Rebar Snap hooks - T4828 -1/CS


The TracBloc self-retracting lifelines are made of a shock absorber and a self-retracting lifeline. They are designed to be used as a connecting device in a personal fall arrest system. The TracBloc self-retracting lifelines connect the user’s harness to the anchorage point. Typical applications are: warehouse use, order-picker, manufacturing, scaffolding, construction, elevated platforms and general maintenance, repairs and operations.

The TracBloc self-retracting lifeline allow freedom of movement in elevated areas, and eliminates tripping hazards and dangerous falls normally associated with fixed length lifelines. In case of a slip or a fall, an internal locking system immediately activates to arrest the fall.

The self-retracting lifelines have a webbing wound on a spring-loaded drum. They are supplied with a 3⁄4 in. (20 mm) self-locking snap hook at the shock pack end and 2-1⁄2 in. (64 mm) self-locking snap hooks at each arm. A fall indicator label is sewn on the shock pack.

The new design includes a new housing made of thermoplastic material making it lightweight, robust and resistant to impact, wear, abrasion and ageing. It also has an improved responsive system that, in an event of a fall, allows the breaking system to function quickly (in less than 10 cm [4 in.] drop), thus reducing the distance of the fall. Additionally, the new design is equipped with a new spring system that improves unwinding without sticking (blocking) points during use.

The purpose of the shock absorber is to lower the impact force experienced in a fall by dissipating the kinetic energy and controlling deceleration. The shock-absorbing device is made of a specially woven webbing that elongates through tearing on its weave and stitching. This action limits the impact force to an average arrest force of 900 lb. (400 kg) for the one arm TracBloc and 1,350 lb. (610 kg) for the two arms TracBloc 2.

The TracBloc 2 has two arms and allows the worker to remain safely connected at all time (100% tie-off) while climbing or on the move.
