Single arm rotary boat/raft davit(with crane)

  Single arm rotary boat/raft davit(with crane) This equipment uses hydraulic drive rotary type,by its own gravity of the boat to make it down to the water,which could make the boat slew to outboard in case of losing of the power supply.While lowering,the sailors in the boat could pull the remote control steel rope,through the pulley around the reel.To lift the winch hammer to control the boat/raft lowering or stop.This also could be operated by sailors on the operation deck.The winch is use of motor-driven winch gear box and gear box with centrifugal speed and manual brake function delegaed.The device is designed and manufacturing according to the latest SOLAS standards and international standards. The single arm rescue boat/raft lowering device and crane main technical specifications type Max working load Hoisting load Hoisting speed Landing speed Rope capacity of the reel Rotation radius SARC21 21KN 14KN is more than or equal to 18m/min 40-60m/min 30m 3600-4500mm SA23-1 23KN 14KN 3600-5400mm SA23-2 23KN 18KN 3600-5000mm  Crane main technical data Max.hoisting load Rope capacity of the reel Maximum rotation angle Landing speed Rotation radius 30KN 30M is less than or equal to 330o 11-15m/min 4100-5000mm 15KN 4100-7300mm 30KN 4100-5500mm 275N CE approval inflatable life jacket  CO2 fire extinguishing system Marine horizontal/vertical oil fired boiler Marine air compressor marine centrifugal pump marine hydraulic steering gear Hydraulic capstan Tunnel thruster/bow thruster
