SG9:15 -Use, Inspection & Maintenance of Lifting Equipment and Accessories for Lifting in Scaffolding
*Introduction
Most scaffolds require at least one simple lifting device to raise materials to the necessary working height. Gin Wheels are the most widely used.
Types of Gin wheel
• Ring type gin wheel
• proprietary Gin Wheels
*Competency Requirements
• Trained person
• Training from a competent trainer.
• The employer should also monitor their attitude and aptitude towards safety and Gin Wheel & Rope work and ensure adequate supervision.
*LOLER Certification Lifting Operations and Lifting Equipment Regulations 1998 (LOLER)
• The employer must arrange for thorough inspections as per LOLER, with gin wheels inspected every year and all accessories (including ropes) inspected every six months. Copies of these certificates must be retained, with copies held on site.
• The Gin Wheel and Rope must be fit for purpose.
• The serial number on the Gin Wheel must be the same as the certificate.
*Pre-Use Check
*Weekly Inspection
*Exclusion Zone- a territorial division established for various, case-specific purposes.
*Protruding Tube Risks
There must be no protruding tube (e.g. transoms) underneath the Gin Wheel to ensure there is no risk of any material striking protruding tubes and falling to the ground. Where there are tubes protruding, these must be cut or replaced with shorter tubes, before operations commence.
*Fixing Gin Wheel Safely
• On typical independent access scaffolds, for example, the
Gin Wheel & Rope tube should be fixed to the inner and outer uprights with double couplers.
• The wheel should be secured in position with 2no.
• Right angle couplers either side of the wheel, with the wheel positioned no further than 750mm away from the outside leg.
• If a joint occurs in an inner standard between the horizontal gin wheel support and the lift below, the joint should be made with a sleeve coupler, rather than a joint pin, to resist uplift. Alternatively, a short section of tube may be spliced across the join and connected with two swivel couplers or band-and-plate couplers.
*Maintaining Clear Sight of Each Other (ensuring good communication)
• The operatives involved in lifting operations must have clear sight of each other and maintain good Communication at all times.
Their must agree on a system of verbal and non-verbal signals BEFORE work starts.
*Tying Material Off Correctly
• A single tube should be securely fastened by tying a rolling hitch knot approximately a third of the way along its length. Alternatively, if the tube is to be lifted vertically, the rolling hitch knot should be tied approximately halfway and a half hitch knot should be tied at the top to keep it suspended vertically.
• A timber hitch is normally used to tie boards, as shown below and scaffold fittings must be hoisted in proprietary bags/buckets tied with a rolling hitch.
• All hoisted loads must be of the same length (e.g. no mixing 2.4m tubes with 2.0m tubes for instance).
• The maximum mass that can be hoisted on a Gin Wheel is 50kg, but please note that this also includes the weight of the rope.
*Tying Material off (Hoisting Material Upwards)
When the scaffold operative ties off the material and hoists it up to the operative at the top he must have clear sight of the top man (and vice versa), and maintain good communication.
*Tying Material off (Lowering Materials)
The same sequence will be used in reverse.
*Inclement Weather
The employer must risk assess inclement weather and when work must cease due to inclement weather (e.g. High winds).
*Close Down Operations
The Gin Wheel & Rope must be made safe at breaks and at the end of the shift (which may require the removal of the equipment to a safe place, if it is likely that others might abuse the equipment).
*HAND LINES
Instead of using Gin Wheels, a ʻhand lineʼ may be used to tie materials to a fibre rope, typically of a 12 mm diameter, and haul them up by hand. Hand lines are typically suitable for lifting materials of up to 20 kg.
