Construction weight (t)800Structure & Function Hydraulic Static Pile Driver consists of clamping and piling mechanism, lifting mechanism, hoisting mechanism, hydraulic system, electric system, etc, with the functions of hoisting, pressing, walking and steering. Operational Characteristics 1. Civilized construction; Clean; No noise; No vibrations; No construction wastes. 2. Reliable Construction Quality; Piling process is similar to static load testing, where pile bearing force can be displayed. 100% pile success rate is guaranteed. 3. Fast piling and High efficiency; One HSPD can drive piles in total of 600 800m per 8 hours, much faster than other modes. Especially suitable for large-scale or time-constraint projects. 4. Walking and steering freely. Easy to align piles. 5. Compact conformation. Easy to disassemble & assemble. Application Scope 1. No limitation on pile length. Suitable for construction in clay soil, soft soil and sand bed foundation, or in the Karst areas with low earth covering, or by riversides, or in coastal areas with deep bearing stratum. 2. No noise, No pollution during construction, especially suitable for operations in areas with noise control such as schools, social communities, and urban areas. 3. No vibrations. Suitable for vibration-control areas such as subways, overpass, dangerous buildings, precision instrument buildings and those nearby banks. Technology features Except for the general technology performances of the same grade products by domestic HSPD manufacturer, Tali pile driver is of yet some unique original technologies as follows. 1. Unique top-jacking design. Tali HSPD can be applied by not only clamping but also jacking or the two simultaneously. This mode can reduce the clamping stress effectively to avoid damaging the hull, especially of the thin-well pipe piles. (Patent No.: ZL02139875.7) 2. Original structure design of lifting leg.This features has changed the supporter of radial force from the lifting cylinder of pile driver during longitudinal walking. By this way, it is possible to avoid the damage of the lifting cylinder rod and the guide thimble, improving resistance to strain injury, impulsion, and weariness greatly. (Patent No.: ZL01249443.7) 3. Practical clamping mechanism. It can meet the needs of square pile, pipe pile and H-type steel pile only by changing the grippers. The grippers can adjust its orientation according to the pile surface to ensure enough contact to the pile, and to avoid pile damage.(Patent No.:ZL200820210908.5) 4. Ingenious conception in the design of the border and corner pile mechanism. The border and corner piling force can reach 60%-70% of center piling force. (Patent No.: ZL02277982.5) 5.Flexible and adjustable guiding pile unit. Original universal guiding pile mechanism, which can effectively adjust the size of the piling hole, is applicable for various shaped concrete pile.The mechanism can guarantee the safe press of the pile,reducing the labor intensity and improving construction efficiency.(Patent No.: ZL200820210907.0)
