Trolley Rail Fall Protection System
When working on rooftops or within restricted spaces near vertical drops, safety is paramount. Our Horizontal Trolley Rail Systems provide an effective fall protection solution, offering mobility and security.
A horizontal trolley rail system is a type of rooftop fall protection that enables workers to have horizontal mobility while being simultaneously restrained from falling over the roof edge. This system can also be referred to as a horizontal rail fall protection system or a fall protection trolley system.
When workers require horizontal mobility while working or rigging within close proximity to an unprotected vertical drop, conventional single-point anchors may prove impractical or insufficient. By contrast, horizontal rail systems are ideal for long, restricted spaces or tight quarters, providing non-restrictive fall protection and an effective means for suspending direct and primary rigging equipment.
Horizontal trolley rail systems differ from horizontal cable lifeline systems because trolley rails are considered a somewhat non-restrictive fall protection system. Unlike cable systems, trolley rails are designed and engineered for multi-purpose applications, including:
• fall restraint lanyards
• fall arrest lifelines
• direct rigging or attachment of primary suspension lines when rigging a bosun's chair with descent control equipment
• attachment of tie-back lines when using outrigger beams or parapet wall clamps (stage, cage, or bosun's chair).
When is this form of fall protection implemented?
Horizontal Trolley Rail Systems are designed primarily as rooftop fall protection for horizontal applications. It allows for horizontal mobility over extended distances while working close to a vertical drop, e.g., within 6'-0" (1.8 m) of the roof edge, skylight, or any high, narrow, level roof area or walkway not protected by a guardrail at least 42" (1067 mm) high.
It is ideal for long, confined spaces or tight quarters, such as attaching lanyards or horizontal lifelines, or direct rigging of suspended equipment for both interior and exterior applications. This is an alternative to single anchor points when independent anchors do not provide the required degree of safety, and it complements conventional vertical lifeline anchorages in or around confined spaces.
Types of Horizontal Trolley Rails
Pro-Bel offers several types of trolley rail systems. Each has been engineered to satisfy a particular job requirement. They can be categorized as follows:
1. Aluminum Horizontal Trolley Rail:
An extruded aluminum rail that houses a traversing trolley assembly along one side of the rail. Advantages include light weight and ease of installation.
2. Steel Horizontal Trolley Rail:
A steel beam section is available with a trolley assembly on one or both sides of the rail.
Both of the above category rails are supplied complete with a roof or other type of supports or securements. In all cases, workers secure their lines to a U-bar trolley assembly. Any number of trolley assemblies may be specified for use on rails.
