Brackets, tie offs and hoist systems are described as well as methods of securing same to telecommunication and other towers. The bracket may be secured to the tower by one or more leg straps, leg clamp bars or one or more cable systems. The cable systems may be rotatably attached to the brackets allowing for adjustment of the cable system. Adapter brackets are also described that comprises different shaped recesses for attachment to different style towers. The bracket may comprise a vertically-oriented eye bolt attaching a D-ring to the bracket or and/or a hoist beam supporting one or more sheaves may be secured to the bracket.
F16B 2/08 - Clamps, i.e. with gripping action effected by positive means other than the inherent resistance to deformation of the material of the fastening external, i.e. with contracting action using bands
Hoists; Portable hoist systems; hoisting kits for allowing workers to service telecommunications towers above the ground comprising metal beams, metal poles, clamps and chains especially adapted for hoists; telecommunications tower service kits, namely, hoisting kits comprising portable hoist systems, metal beams, metal poles, clamps and chains

Hoists, platforms and davits are described as well as methods of securing same to telecommunication and other towers. The hoists, platforms and davits may be secured to the towers on a temporary basis using clamps. The clamps may include brackets and cables. The cables may be attached to the brackets, may wrap around the outer surface/perimeter of the tower pole/leg and may use tension to keep the bracket in place.
