Operation weight: 51000kgLifting capacity: 70000kgMax. Lifting moment at min. Range of the boom: 836 (686knx1. 22m)  (kn. M) Max. Lifting moment at Max. Range of the boom: 784 (156. 8 knx5m)  (kn. M) Boom length: 7000mmMax. Lifting height of the hook: 5200mmHoisting speed (six times) : 6m / minTime of change range: 60sModel of chassis: pd320y / ty320bEngine: cummins nta855-c360Rated power: 239kw / 2000rpmTrack gauge: 2380mmLength of track on ground: 3620mmTrack shoe width: 760mmRated working pressure of system: 20mpaLifting winch: hydrauliclly driven, planetary transnission, free-fall functionDiameter of wire rope: 22mmRanging winch: hydrauliclly driven, planetary transnissionTemperature of surroundings: -20--- + 40Overall dimension for transport: 5. 4x3. 43x3. 30mDgy series pipelayer use cummins engine and special designed chassis which has rigid structure, longer and wider track and hydraulic-mechanical transmission. Working device use hydraulically drive to carry out 3 actions: up and down of the hook, swing of the boom and up and down of the counterweight. Double independent hydraulic winches are used to drive the boom and hook. Boom is made of dilute alloy and high strength steel, solid welded box-section, moment limiter, height limiter and boom limiter are equipped to inspect and control the working status of the pipelayer. The pipelayer jiggle performance is good and has the emergency free-fall function on load, dgy series pipelayers are important equipments in oil and natural gas pipeline construction which mainly used for the pipe laying, linking and loading.
