Higher demands are also asked for the performance and reliability of the railroad aisle stacking crane. After the synthesis has compared several kind of constructions elevators overall plan, uses the steel wire to hoist the type, its structure simple, the stress is clear about, the users also familiar. The security guards against falling，highly the spacing installment takes the construction elevator the safekeeping of security installment which can avoid the falling of the cage to assure the people and goods safety as soon as the construction hoist meets accident. The security guards which make use of wedge block for brake. This safety anti-falling device have high sensitivity，good reliability，simple configuration and easy to test，which can availably avoid the failing accident of the cage. The Fork trip with a double body is a three-tier telescopic fork, when fork is recovered, the length of its own is far less than the width of roadway, when accessing to goods, the fork is much longer than the width of roadway.
