Each class of cranes has its own basic characteristics must suit to particular application and the job.

Job requirements consistency-Weights and dimension of loads

-Movement of loads: materials lifting methods and working areas

-Work Load: Number and frequency of lifts

-Operational Time: hour per week

-Space available for crane access, erection, operation and dismantling

-Special operational requirement or limitation imposed

TYPE OF CRANES - GENERAL

5.) Portal Leg.

COMMON USE IN THE MARKET - FOUNDATION

-For construction where no undercarriage or cruciform base can be set up due to constricted room

-Safety places the crane above of streets, pedestrian walks etc. > Safe construction works without affection of traffic or other actions

1.) Internal Floor Climbing Crane. (內爬式)

COMMON USE IN THE MARKET – ADJUSTMENT IN HEIGHT

Advantages:-Supporting by ground beam or structural wall-Limit space required only (2.4m x 2.4m; slab opening)-Cost saving on hiring extra tower mast section

Disadvantages:-Backfill the slab opening after climbing-Material cost for fabricate supporting H-beam-More time consume on preparing work; e.g. relocation of collar frame

2.) External Climbing (外爬式)

Advantages:- Less extra work after climbing - Less preparation time

Disadvantages:- Pay for extra tower mast section - Extra cost on transportation - Take longer time on dismantling, more expensive

SELECTION OF CRANE - APPLICATION

The construction site determines the tower crane capacity and crane type -SIZE: What type of material to be conveyed.

-WEIGHT: What is the heaviest weight of material.

-TIME: Logistic of material flow at site.

-WORKING AREA: Location of tower crane.

-SPEED: Hoisting speeds are direct indication of cycle time

-NOISE: Low level of operational noise (dBA) for construction site to apply for

Construction Noise Permits (CNP)
