Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces LY/T 1169-1995 "Technical Specification for the Erection and Disassembly of Aerial Cableway for Forests", compared with LY/T 1169-1995, the main the technical changes are as follows.

--- Revised the standard name "Technical Specification for the Demolition of Aerial Cableway Erections for Forests" to "Establishment and Operation of Forest Engineering Aerial Cableway and dismantling technical specifications";

--- Revised the scope of the content (see Chapter 1, Chapter 1 of the 1995 edition);

--- Revised the normative reference document (see Chapter 2, Chapter 2 of the 1995 edition);

--- Added the terms and definitions of "span, chord inclination, installation tension", and removed the terms and definitions of "hoisting angle" (see Chapter 3, Chapter 3 of the 1995 edition);

--- Revised the content of the preliminary work of the erection phase (see 4.2, Chapter 5 of the 1995 edition);

---Modified the requirements for the installation of the winch (see 4.3, Chapter 7 of the 1995 edition);

--- Increased the consolidation of load-bearing cables and other steel cables and anchor piles (see 4.4);

--- Change the "installation of standing timber brackets" to "installation of guide pulleys" and modify its contents (see 4.5, Chapter 8 of the 1995 edition);

---Modified the contents of the installation of the saddle (see 4.8, Chapter 10 of the 1995 edition);

--- Increased the selection of steel cables (see 4.9.1);

---Modified the connection of the cable (see 4.9.6, Chapter 12 of the 1995 edition);

--- Increased the fixed content of the suspension sports car and the stopper (see 4.11);

--- Modified the content of the load cable tension (see 4.12, Chapter 14 of the 1995 edition);

---Modified the trial operation of the ropeway line (see 4.13, Chapter 15 of the 1995 edition);

---Modified the removal of the ropeway (see Chapter 6, Chapter 16 of the 1995 edition);

--- Removed the contents of maintenance and maintenance (Chapter 18 of the 1995 edition);

--- Added the content of "rope transfer" (see Chapter 7).
