Scaffold

V-shaped pole scaffold is called general-purpose due to the range of applications which is wide enough.

The use of V-shaped pole scaffold in the construction industry covers finishing operations and remedial work, facade works and erection operations as well as brick work.

In a similar fashion this type of scaffold can be used while the erection of the supporting frames for the shuttering.

The scaffold design allows changing the arrangement of framework according to the building architecture aspects.

The scaffold is operationally easy-to-use and reliable.

The manufacturing process includes cottering.

Geometry of scaffold framework structure includes modular meshes which are stationary due to the adequate mounting of horizontal diagonals and braces.

Construction design

It is a system of support pillars, ledgers, horizontal diagonals and braces made of steel pipes.

Round flanges are welded to their walls at a certain distance. The V-shaped tags fitted with collars and jags are welded to the horizontal diagonals on both sides.

The equivalent tags are hinge mounted to the oblique diagonals.

While scaffold assembling these tags are mounted to the support pillar flanges and fixed with demountable wedges ensuring the reliable fixing of mutual alignment of components.

The wedges are fixed on the horizontal constructional elements and diagonals.

You must admit that this type of fastening is reliable enough.

However it must be like this. In fact not only the quality of constructive activities depends on the reliability of the scaffold but the life of the employees of the company as well.

An ordinary hammer is the tool which an assembler uses in perforating the wedges.

The wedges are made of special-property alloy providing their multiple uses.

It is not necessary to carry wedges in the pocket or in the bag. They are fixed on the horizontal components and diagonals.

The scaffold can sustain a load up to 700 kg/m2, as well as be raised through a height of approximately 100 meters, negotiate any relief and be fixed on the irregular surface.

BEFORE SCAFFOLD ASSEMBLING IT NECESSARY TO PERFORM THE FOLLOWING:

  • Identify and protect a dangerous area at work;

  • Check status and performance of the scaffold;

  • Check the supplied equipment set for completeness;

  • Clean and prepare the work area where the scaffold will be mounted;

  • Perform the scaffold installation in accordance with the specific mounting schemes.

OPERATING INSTRUCTIONS FOR WORKING OPERATIONS PERFORMED ON SCAFFOLD

  • When working on scaffold it is required to consider the design load. The overloading of working tiers is not allowed.

  • The scaffold must be properly fixed to the front according to the rules and regulations or in accordance with the mounting scheme issued at the request of the customer in case of renting or purchase;

  • While the performance of any construction activity on the scaffold workers must use safety harness;

  • Before starting work the scaffold must be grounded and fitted with the lighting-conductor.

  • In case when the attaching point of scaffold to the front is against the window or any other opening, the scaffold must be secured from the inside of the building;

  • Construction activities and finishing operations should be carried out only after the complete installation of the construction;

  • Persons who have no specialized training, who were not familiarized with the project entrance orientation, as well as persons who are irrelevant to the conducted operations should not mount on the scaffold.

  • Before starting work site engineer, site supervisor and supervising engineer must check the reliability of the construction mounting before the start on the constant basis.

  • Hauling winch, lifting tackle and other lifting equipment must be attached to the front of the building and not to the scaffold.
