Feature of QD100 Derrick Crane 

(1) Special design of separate-settled. Low center weight of gravity in slewing, large lifting capacity and reasonable mechanism design. 
(2) Big luffing range. the slewing radius can reach 24 m. More efficiency will come true by changing luffing range under rated load. 
(3) Three mechanisms-lifting, luffing and slewing, with satisfied performance in shifting and high efficiency, are operated easily. 
(4) with kinds of safety facilities, as limiter for lifting moment, slewing limiter and luffing limiter. Once over load happen, the facilities will turn down power automatically right away. 
Also, an electronic transducer for load is fixed to cut down power when overloading appears. 
(5) Installation and disassembly is convenient. the product can be transferred to other site in short time and maintenance is very easy and convenient. All spare parts satisfy relative standards. 
(6) Electric control box is equipped to the crane which is operated easily and safely.
