2.10 Safety-conscious operation
• ST chain hoists are constructed according to the state of the art and equipped with a
slipping clutch as overload protection. In spite of this, dangers may arise from inap-
propriate use or use for an unintended purpose.
• The user is responsible for ensuring that work is carried out with safety in mind and
avoiding risks, see chap. 1.6.
• Read the instructions before starting to work with the product.
• Standing under a suspended load is forbidden. Danger to life and limb!
• Observe the "Duties of crane operator".
• Before starting work, find out where the emergency stop button is (usually in the
control pendant).
• Do not put your hand between edges that might crush or cut.
• Do not grasp the moving chain.
• Take note of the relevant instructions when attaching loads.
• Do not stand between load and wall.
• Start lifting the load carefully.
• Never attempt to remedy a malfunction while the load is suspended.
• Never use bent, open or distorted load hooks, or attempt to straighten them.
• Have a damaged hook latch repaired.
• Never anneal the hook.
• Never lock the buttons of the control switch in place.
• Never allow the load to drop into the hoist’s load-bearing equipment.
• Before lifting loads, ensure that the stated maximum working load is not exceeded.
• When lifting and setting down loads, ensure that they are in a stable position in order
to avoid accidents due to the load toppling or overturning.
• Secure the load if the power is cut.
• Have a damaged hook safety latch repaired.
• Do not kink or crush control cables.
• Choose a safe place from which to operate the hoist.
• Joining or mending ropes, chains or belts is not permitted.
• Never touch metal components that are colder than 0°C or hotter than 55°C without
wearing protective gloves.
• Report damage and defects to the product (abnormal noises, impaired braking
function, deformations, ...) to the person responsible immediately. Do not use the
product until the faults have been eliminated.
• Do not remove information plates from the product. Replace illegible or damaged
plates.
• Never expose control cables to tensile stress. It is strictly forbidden to move the hoist
by pulling on the control pendant.
• Have hoist inspected by the relevant authority before commissioning.
2.11 Attaching load
• Use only tested and approved slings for attaching the load.
• The rope must not be wound around the load.
