Safety feature
Overload protection: equipped self re-setting overload protector, the hoist motion is stopped if overloading occurs,
but lowering is permitted, making the crane safe
Lifting limit switch: adjustable, geared 4-step rotating limit switches, self re-setting, slow down and
stop
Upper and lower limit switch (Hook / Slack chain stop operated)
End stop: energy-absorbing rubber buffers
Wireless anti-collusion limit switch: infra-red type
Overheating protection: equipped with imbedded bi-metallic thermal switch (or thermistors) in the
windings to protect against overheating
Electrical braking is provided in all circumstances and the mechanical brake is used only as a
holding and emergency brake
