Mobile suspension jibs that allow very fast access to building facades, Modular Galvanised

The mobile portable suspension jibs allow very fast access to the building facades using many types of temporary platforms.

Portable suspension jibs are robust and easy to assemble and to dismantle. They represent the ideal solution for nearly every flat roof,  especially when the parapet is not strong enough to hold a load. The stability of the jibs is provided by counterweights. no roof penetration is required, reach (cantilever distance), height and SWL to our customers requirements.
Please contact our sales team for advise and / or a quotation.

Important: Not certified for rope access, however previously known to be used by companies for rope access, but under their own risk assessment.

 System 1  System 3  System 2

System Setup 1

Telescopic beam mounted directly on front and rear crossbars can be moved on Castor wheels. This assembly is to be used where parapet height does not exceed 1 foot (0.3 m).

System Setup 2

A height adjuster fitted to the front crossbar lets the overhead telescopic beam pass over a 4 ft (1.22 m) high obstacles (chimneys, ventilation shafts, parapets, etc.).

 

System Setup 3

Fitted with reinforcement brace and tensioning wire rope, this model is recommended for longer overhangs or very heavy suspended loads (e.g pulley-block mounted on suspension wire rope, etc.).

(a) - 0.4 m to 1.6 m

(b) - 1.4 m to 5.2 m

(c) - upto 0.3 m (1 ft).

(a) - 0.4 m to 2.0 m

(b) - 1.4 m to 5.2 m

(c) - upto 1.22 m (4 ft).

(a) - 0.4 m to 2.0 m

(b) - 1.4 m to 5.2 m

(c) - upto 2.0 m (6 ft 8 in).

Usable adjustments: (a) - overhang, (b) - distance behind the fulcrum & (c) - height adjustment.

*** Please note, these units are fully adjustable between the measurements above, but effect the required amount of counterweights you will need to use with the system, either refer to the tables below our use the pricing tab for a fully automated configuration tool. ***

*"Working load limit" (WLL) should be taken to mean the nominal capacity of the hoist and not the actual suspended load. The loads indicated above apply to the capacities of Tirak hoists.

Calculation of Counterweight

The tables below illustrate the number of counterweights needed for the different capacities (WLL) depending upon the overhang (A) and the distance (B) behind the fulcrum line. It is always better to have the maximum distance (B) behind the fulcrum line, depending of course of the space available, to reduce the number of counterweights and consequently the wheel loads on the roof. Furthermore this makes assembly and dismantling much easier.The total length of the telescopic jib (A + B) should not exceed 5.60 m.

**(¹) Ra max = dynamic reaction per front wheel, with the platform suspended (dynamic factor = 1,25). For final reaction per front wheel (operating load multiplied by a factor of 3): multiply the Ra max. values by approximately 2.2.
(²) Rb max = maximum reaction per rear wheel, with the platform on the ground.

Safety and Assembly

  • Fall protection is required on all suspended platforms.
  • Only persons familiar with the rigging techniques and the equipment are authorized to assemble our Suspension Beams.
  • Check daily the condition of the various components Use only OEM parts
  • Before assembling the counter-weighted beams, always make sure that the roof and the parapet are capable of carrying the loads applied by the suspended loads. If necessary, refer to static calculations.
  • On all roofs, place planks or channel under the wheels to safeguard the roof to obtain better load distribution.
  • Space permitting, extend the telescopic beams up to its maximum length in order to reduce the required number of counterweights and ease
    assembly and dismantling.
  • When the assembly is finished, lock the brakes of the castor wheels.
  • Before moving the beams around on the roof, lower the platform to ground level and slacken all wire ropes.

CAUTION

Almost 80% of all accidents occurring during work on suspended scaffolds are caused by incorrectly installed SUSPENSION SYSTEMS or incorrectly calculated counterweights. Ensure lifting device is tested before every use when using with this system.

Assembly

Portable Suspension Beams have been designed specifically for use with our Suspended Scaffolds. They can be used equally well for  suspending any other type of suspended scaffold that consist of standard elements thus permitting the following basic assemblies:

System setup 1Portafix A assembly

Telescopic beam mounted directly on front and rear crossbars can be moved on castor wheels. This assembly is to be used where parapet height does not exceed 1 foot (0.3 m).

System setup 2

Portafix C Assembly

A height adjuster fitted to the front crossbar lets the overhead telescopic beam pass over a 4 ft (1.22 m) high obstacles (chimneys, ventilation shafts, parapets, etc.).

System setup 3Portafix B assembly

Fitted with reinforcement brace and tensioning wire rope, this model is recommended for longer overhangs or very heavy  suspended loads (e.g pulley-block mounted on suspension wire rope, etc.).
