•
Use only genuine Holmatro accessories and ensure that they have been attached correctly.
•
Stop immediately if the system makes strange noises or displays aberrant behaviour.
•
Always use a pressure gauge to monitor the pressure in the system.
•
Do not lift unstable loads.
•
Take extra care when lowering a load.
•
Return inactive equipment immediately to the tool station.
•
During lifting, maintain a safe distance to the lifting bags. The kick-out zone depends on the
situation and must be determined by an expert.
•
Always adhere to the safety regulations that apply to other equipment that is used in the operation.
2.7
Safety regulations with respect to maintenance
•
Wear personal means of protection when performing maintenance tasks.
•
Never work in a way that could jeopardize safety.
•
Used or leaked fluids, and any other products consumed during the activities, must be collected and
disposed of in a environmentally responsible way.

Description
3.1
Equipment
Holmatro series HLB lifting bags are made of high-quality rubber internally reinforced by three aramid
plies throughout the circumference. The special rubber blend is flexible, airtight and has a good
resistance. Each lifting bag is extensively tested in our factory (test pressure 20 bar) before despatch.
The use of these bags is virtually unlimited both for industrial use and in rescue operations.
The specially designed pattern provides a unique grip and "interlocks" with other HLB lifting bags. Each
bag (except HLB 1) is provided with a centring star on both sides, a unique serial number (applied to the
rubber at the air inlet) and a production date (giving the month and year of production of the lifting bag).
The lifting bags are inflated with air at a maximum pressure of 8 bar. Inflation is realized by admitting
compressed air from a compressed air source (by a pressure regulator from 200 to 300 bar to 8 bar or
an 8 bar compressor, for example), via a control unit and a system of hoses to the lifting bag. As the air
enters the lifting bag under pressure the lifting bag will fill.
The load will be moved as soon as sufficient pressure and lifting capacity is available. As the lifting bag
is inflated further its effective pressure surface area decreases, resulting in reduced lifting capacity
(Refer to Fig. 4).
