Gin Poles

Your premier manufacturer of Gin Poles built in the USA using 100 % recycled U.S. steel. You will not find a more reliable pole manufactured with the quality and backing that Landa Mobile Systems, LLC provides.

There has never been a failure or incident involving a  Landa Manufactured Gin Pole when utilized with the guidance of an engineered work plan. Safety is our priority, and we are committed to building the safest gin poles in the northern hemisphere, which are now used worldwide in telecommunications, ship loading, and oil platforms.

GPA poles are heavy-duty, lightweight aluminum field transport round gin poles Manufactured to ANSI/TIA-322.   WARNING: “Round poles are not man Rated.”

Round Gin Pole, Manufactured to ANSI/TIA-322   WARNING: “Round poles are not man-rated.”

Triangle Gin Poles  WARNING:  Our Triangular Gin Pole is the gross load. Man Rated “when lifting personnel shall not exceed 50% of the charted safe lifted loads. No other construction loads shall be lifted with personnel”.   We are not participating in AISC.

Square Gin Poles  WARNING:  Our Triangular Gin Poles gross load. Man Rated..  “when lifting personnel shall not exceed 50% of the charted safe lifted loads. No other construction loads shall be lifted with personnel”. We are not participating in AISC.

Gin Pole Classifications

Basic Gin Pole Information Required to Re-Certify Poles 

  1. Mill Report on steel, citing TIA -322, Pg 55:56 The buyer must maintain a mill report for the life of the gin pole by ASTM A6 OR A568.
  2. Charpy report on steel to -40, citing TIA 322, Pg 55:56, states that the buyer must maintain a Charpy report for the life of the gin pole by ASTM A370.
  3. Welding inspection reports citing TIA 322, Pg 55:56
  4. Pole original engineering matching that pole serial number, citing TIA 322, Pg 55:56
  5. Each section must have a consecutive serial number stamp on it, citing TIA 322, Pg 55:56
  6. All poles must have serialized documented product numbers with associated paperwork, citing TIA 322, Pg 55:56
  7. Complete records of pole inspections.
  8. Magnetic particle inspections shall be recorded on 10% of the welded connections every ten years. 

Annual inspection reports shall be maintained for a minimum of two years.

We maintain records of all poles and have a history and original manufacturing documentation in case of loss.

OSHA Required Forms Supplied with all LMS Gin Poles 

  1. Annual Pole Certification signed and numbered
  2. Annual Pole Inspection Report signed and numbered
  3. V.T. Visual Welding Inspection Report, done at the time of manufacture
  4. Mill Report on steel specification ASTM A500, Grade B/C
  5. Charpy report on steel temperature test to –40 degrees
  6. P.E. Stamped Pole specific Load Chart
  7. Structural steel 100% recycled USA in compliance with AISC or ANSI/TIA-222-G
  8. Each gin pole assembly and associated rooster head is permanently marked, matching its load chart
  9. Sheaves included being permanently marked with the serial number assigned to the pole

Gin Pole Operations:  On the documentation side of things, the operator will need adequate details depicting the planned operational configuration(s) for the complete gin pole system to be used, including:

  • Gin pole mast
  • Top lifting block
  • Load and tagline sizes/configuration (including use of heel block, max load position angle, max tag angle, tag arrangement, etc.)
  • Basket and bridle attachment to gin pole and supporting structure, including associated hardware and sling sizes/config
  • All relevant details about jumping/lowering the pole into position
  • All relevant details about tilting the pole for operation (use of luffing block, etc.)
  • Any other relevant details based on the user’s planned operational configurations for assembly, setting, jumping, arranging, lifting, and removal of the system
  • As pole manufacturer Landa, we only address the gin pole mast and allowable load and tag capacities/angles based solely upon the mast’s rated strength. The pole was designed and built, and load charts are under the ANSI/TIA-322 standard. The operator is responsible for ensuring they comply with all related regulations. 
  • Complete records of pole inspections and records of magnetic particle inspections shall be performed on 10% of the welded connections every ten years.
  • Annual inspection reports shall be maintained for a minimum of two years.
  • All gin pole operations must comply with the latest revision of ANSI/TIA-322 and the OSHA CPL 2-1.36
    Maintain your required documents, the work plan, and the engineer sign-off for each job.
  • ANSI/TIA-322 standard includes an impact factor of 1.7 for all gin poles using synthetic load-lines. 
  • Gin Pole storage racks for gin poles are recommended for safe transport, storage, and return shipping for inspection service. These units protect and reduce the potential of damage from excess handling with forks, etc.

WE WILL NOT PUT PEOPLE’S LIVES AT RISK.
Know the Regulations and order the new ANSI/TIA-322 and OSHA CPL 2-1.36. Rigging plans for all gin poles must be prepared according to the ANSI/ASSE A10.48. Our standard load charts are relevant where wind speed does not exceed 30 mph gust at any given elevation during the proposed lift. 

“Load carts are not interchangeable” and do not match older models. Load Charts supplied are pole-specific with serial numbers matching the pole and expire with annual inspection re-certification.  

Upon submission of your re-certification completion, new load charts are available from the factory.

Modifying, welding, or changing the gin pole OEM structure invalidates all warranty and company liability. Gin Pole charts will not be issued for pole structural changes not performed by OEM without Landa performing an inspection and a mag particle inspection.
