HD-Range (Heavy Duty Mast) - Pneumatic Telescopic Hilomast

Heavy Duty Mast - HD Range The HD-Range of masts has been designed to the highest possible specifications and standards.  The lifting capacity of the HD-Range of masts is significantly greater than other Hilomasts even when deployed at maximum heights.

The flexibility of the HD-Range of masts comes from using heat-treated aluminium tubes that increase in 1⁄2” increments.  This allows the HD-Range masts to have larger top sections, in turn, strengthening the masts' capacities.  These 1⁄2” increments also allow the HD-Range to contain up to 12 sections which allow more flexibility than ever before in meeting the customer's specific requirements.

Positive locking collars have been incorporated into the HD-Range masts.  HD-Range masts are manufactured from the highest quaility material and have increased bearing width which reduces the friction.  Anti-rotation keys are 20% longer, giving our strongest resistance to torsional loads yet.

The table below shows the HD-Range of masts and is only a small selection of masts available.  All masts in the HD-Range are modular by design.  By adding sections and adjusting tube lengths, masts can be produced to fit specific customer requirements, often with little or no increase in delivery time.  Finish, color and other options are availabe.  Please contact our sales team for a detailed quote to fit your exact requirements.
