Load Lifting Mast
Lightweight, mechanically resistant, easy-to-install tools that provide significant gains in safety and productivity when lifting equipment and materials. They are ideal for building and maintaining medium-voltage overhead networks.
Made from cast aluminum metal components and RITZGLAS® insulating tubes, our masts are synonymous with durability and efficiency.
NOTES
– The masts are designed for vertical lifting applications. They are not suitable for lateral pulling on a hand rope or a misaligned load. The direction of force must always be parallel and aligned with the mast.
– When calculating the load capacity, take into account a 10% loss due to friction in the pull ropes.
Using a double hook hoist system, the maximum load to be hoisted will be 635 daN (1400 lb). A reel must be attached to the base of the structure to pass the hooklift’s hand rope through.
With a simple lifting system, the maximum load will be 408 daN (900 lb).
The load lifted plus the pulling force and the friction force equals the capacity of the mast.

With a 920 mm chain saddle for fixing to the pole, it can only be mounted on free areas of the pole (it does not have a spacer saddle)
.

With 130 mm spacer saddle for attachment to the pole using a 920 mm chain, it is coupled with a spacer saddle, which allows it to be installed even next to crossarms. It is coupled to the pole using a chain tensioner and tightened using a handwheel.

With a direct fixing system
,
it is compatible with both double “T” posts and circular posts. For double “T” posts, fixing is done using two screws with a butterfly nut, using the post’s own holes. For circular posts, fixing is done using two conventional metal
straps.
With four fixing positions available, it is important to observe the following nominal working capacities for each position.
1st hole: 100 daN (220 lb) on the base side
2nd hole: 150 daN (330 lb)
3rd hole: 200 daN (440 lb)
4th hole: 250 daN (550 lb) on the top side
